WHY USE "OVER-THE-TIRE" TRACKS?
Traction: If a skid loader is not performing in adverse conditions it is usually because the loader has lost traction. The installation of tracks will greatly restore traction and loader performance.
Flotation: Flotation is a small but important part of loader performance. Tracks increase floatation by contributing to the following factors: (1) Ground Pressure/PSI Rating is reduced by the track laying down a larger footprint than the tire,
effectively reducing the ground pressure of the skid loader by as much as 50%. (2) Traction keeps the loader moving therefore not allowing it to have time to sink. (3) Time: By keeping the loader moving it prevents the loader from staying in one spot long enough to
sink. (4) Too much flotation and performance will disappear due to a loss of traction. This can easily happen
when psi gets down in the range of 3-4 psi.
Wear: Because tracks have less adhesion when turning on hard or abrasive surfaces, they can effectively re- duce tire costs in some conditions. Tracks can also reduce drive train wear by reducing the shock loading caused by the operator spinning the tires and reversing direction to maintain movement when the loader has lost traction.
Ride: Tracks can greatly increase ride comfort in rough terrain as they bridge the rough spots thus smoothing out the ride. The counterbalance weight of the track also helps carry heavy loads smoother and safer.
Cost: Track costs of $1.00 to $4.00 per hour can be very cost effective when considering they allow the loader to do work in conditions where tires cannot. Without tracks, other equipment would have to be brought in or operators would have to wait until conditions improve. The amount of increased production time that tracks return can add up to many times the cost of the tracks. Tracks, for the most part, can be left on year around as performance is increased even in good condi- tions. Tracks need only be removed if surface disturbance or damage is a consideration. These condi- tions can be addressed with the exclusive Grouser Soft Shoe Track.
Tire Protection: Tracks do a very good job of protecting the tender sidewall of the tire. They also have a protective quality at the face of the tire.
Turning: Because tracks create a lower ground pressure they will actually turn easier than tires in many condi- tions.
Conclusion: Tracks are the one attachment that can not only contribute to the performance of the loader but also im- prove the performance of other attachments that one may purchase for the machine and therefore con- tribute to profitability under many job applications.

MARKET PROFILE—OVER THE TIRE TRACKS
Customer profile: Approximately 50% of over-the-tire metal track sales come from the small contractor who uses their skid loader as the primary tool to make money. The second largest track market would be the landscape and nursery market with approximately 30%. The rest of the market would be made up of farmers with poultry or livestock, municipalities, large con- tractors, recycling, foundry, demolition, fertilizer, mining, woods, and other. Rental yards are a fast grow- ing segment in the track market with the introduction of the cost effective EX Combo soft track.
Identifying track customers: There is a potential customer for every loader that is experiencing excessive tire slippage. The most ob- vious conditions are mud and sand but tracks also enhance performance and smooth out the ride even in good conditions. So there are far more potential customers than one would think. Keep in mind if the tires are spinning the loader is not producing and is a potential customer.
Applications in which tracks help sell loaders: Landscaping, spread and level loose material, tree digging and transplanting, mining operations, prepar- ing job sites, moving construction material at job sites, barge and ship unloading, livestock operations, backfilling, working in peat bogs, fencing contractors, demolition, swimming pool installation and any ap- plication that traction, ride, tire protection, and/or floatation is a problem. The soft shoe track is targeted at the market with sensitive areas to work in.
Trends: We see the usage of tracks to continue to be strong with new applications being discovered because of their inherent advantages. Currently about 15% of the new loaders are utilizing tracks and that number is increasing as more people become aware of their advantages. The use of tracks tends to grow rapidly in the areas where the dealer promotes them.
Demonstration tips: Recognize an application to which the benefits of tracks could be appreciated. Many times the dealer thinks the loader doesn’t need any help because after all it is a four-wheel drive unit. He finds out too late that the loader had a poor showing because of a low traction condition, when in fact it was the right piece of equipment but not properly set up for the job. Some dealers have developed a very profitable attachment sale by demonstrating the loader with tracks. Once the customer sees the difference tracks make, they will usually order, even if they feel they will not need them all the time.

GROUSER TRACK—FEATURES / BENEFITS History Grouser over-the-tire tracks were developed over a 12 year period from 1975 to 1987 when the present design was finalized and introduced as the finest track available then and now. Up until 1991 the Grouser track was a hand welded track. In 1991 Grouser installed a robot to do the welding for rea- sons of quality and to keep up with demand. In 1993 Grouser took the ultimate step and switched to a cast pad and link. This improved the product with a better material that is stronger and yields a longer wear life. The Cross-Bar Track has even smoother edges for tire protection and a quality standard that no weldment can match. The Cross-Bar Metal Track is now available for the most popular tire sizes such as 10.00, 12.00, 14.00 and 15.5. In 1999 the Combo Track was introduced for those markets that need the versatility of a track. The Combo Track is an Over-The-Track that has replaceable pads. The re- placeable pads are available as a soft shoe or a steel shoe.
Design The Grouser run loose design was developed to provide maximum performance through flota- tion, traction, cleaning, and low cost per hour to own.
Traction Loss of traction is the number one performance robbing condition encountered by the skid loader. Traction is restored by the segmented design and large cross bars that can sink into the ground effectively controlling ground sheer. The segmented design allows material to squeeze up into the track and tire to prevent spinning by providing the maximum amount of material for the track and tire to push against. Even though the pads that lay between the tires do not significantly contribute to flotation, they play a very important part in maintaining traction by adding to the number of pads that have to be ground sheared.
Flotation The design of Grouser tracks correctly places the most pad area beyond the face of the tire where it belongs and effectively reduces the ground pressure of the skid loader by as much as 50%. Keep in mind that the tire will retain its original ground contact area without any help from the design of the track pad. The area between the tires does not help in reducing ground pressure as can be demon- strated at any time by the ability to pick up the pads between the tires with your hand. Flotation between the wheels can be accomplished only by applying force from the opposite side (such as with rollers). Since there is no down force between the wheels, flotation cannot be accomplished in this area.
Cleaning A high performance track must clean well to perform well. Cleaning is a direct result of the open, segmented pad design that lets material pack in for traction and flotation but allows the material to be ejected by the action of the tire against the material as the tire rotates. The Grouser track utilizes two methods of cleaning. The first is the natural dumping of material as the track sections open and close as they rotate around the tire. The second is the action of the tire against the face of each pad.
Ride Ride is controlled by the equal height and equal spaced pad sections. This ensures that both the front tire that lays down the track and the rear tire that runs over it see the same smooth surface.
Tire Protection and Guidance The track protects the tire sidewall with very large smooth tire guides that will not cut or injure the tire. The tire guides also prevent the track from coming off even though it is run loose.
Rebuildable The nuts, bolts, bushings, links, traction inserts and shoes can all be field replaced using a 3/4” or 9/16” wrench.
Pivot Bushings and Links Bushings for all series of tracks are heat treated to provide maximum wear. The links for all tracks are cast from the same high quality material as the pads. The bushing is locked in the pad so all wear is between the replaceable bushing and link.
Replacement Parts Even though the Grouser track fits small to large tires it was designed with in- ventory and ease of service in mind. Consider that all series A, B, C, D and E tracks produced since 1987 use the same nut & bolt. If replacing links on the older series tracks, one could always upgrade to a 1” size. The E-Series track is now in a class by itself and requires a 1 1/4” bushing and new link de- sign. On the Combo Track the hard and soft shoes are bolt on replaceable as well as the drop in trac- tion inserts.

Track Tension Over-the-tire tracks require slack just like sprocket driven tracks. The Grouser pad is designed to grip the tire not with tension but with contact with the face of the tire. The design does, how- ever, compensate for different tire sizes by allowing the tire to reposition as it rolls into the track. The loader can be driven forever in one direction and the slack will never leave the top and tighten the track.
Weight For the sake of flotation it would be nice to have a light track but experience has proven that the weight has far more advantages than disadvantages. The weight is a direct result of the track being strong and long wearing. The added weight also provides counterbalance to help carry heavy loads safer and sometimes makes it unnecessary to add optional weight kits.
Track Height Track pad height raises the loader up higher than the tires resulting in a different bucket angle and slightly faster travel speed. Here again experience proves that the bucket angle with tracks in the mud and other soft material is not noticeable and the limiting height in most cases is the clearance required to run the track. To keep the track height to a minimum Grouser utilizes approximately a 1.3- inch high pad to provide the maximum amount of material to be worn away in the smallest possible area.
Length Adjustment All tracks must have a method to adjust for length due to different tire sizes, wheelbase and wear. The Grouser track utilizes a very simple method by having available in every pad a long and short hole. This means that every pad is an adjuster pad and the track can be adjusted for length indefinitely.
Installation The track is easy to mount by laying it out, driving the loader on and bringing the ends together over the top between the tires. The ends are pulled together with the web binder provided. With experience, the tracks can be mounted in 30 minutes and dismounted in 10 minutes.
Wheel Spacers It is just as important to provide the proper clearance to the machine as it is to pro- vide the proper track for the loader. A variety of spacers are available in different thickness and diame- ters to accommodate all of the loaders on the market today. All 6 on 6 and 8 on 8 wheel spacers now include male and female pilots for the axle and rim to set on which relieves the studs from carrying all the weight and thus sometimes coming loose.
Cost To provide the finest product is always our goal and to do it at an acceptable cost to the customer can be even more difficult but due to the very efficient nature of the Grouser design, cast construction and the sales volume, it can be marketed at a cost that is extremely competitive if not the lowest avail- able. For example the cost per pound for the 13234-3E track is only $2.41, with the cost per hour to run averaging between $1 - $2. The soft shoe track can run $3 - $4 per hour.
Distribution Grouser tracks are sold and serviced through authorized dealers and OEM agreements in the US and Canada. Grouser also distributes tracks in other parts of the world through distributors and OEM agreements.
References User and dealer references are available on request.
Literature All literature is available upon request along with sample pads to show customers.
Parts The track comes with two extra nuts, bolts and bushings to replace the occasional lost one. The track generally does not need replacement parts until wear demands it and they are readily available from Grouser on short notice.
Warranty The standard Grouser track limited warranty is 2 years against material and workmanship. Wear, abuse, performance and fit are not covered.

FREQUENTLY ASKED QUESTIONS—TRACKS Sales Information Q: Why should I use tracks? A: Even though skid loaders are a great versatile work horse they frequently loose traction in many condi- tions. Tracks do an excellent job of restoring machine performance especially in the areas of traction, flotation, weight balance, tire life and drive system life. Q: How long should the tracks last? A: To give an exact life of a track is not realistic – soil abrasion –machine weight – and operator tech- niques dictate the length of life. We have reports of tracks running in excess of 3000 hours with minimal bushing and link replacement. Cost per hour on usage is about $1.00 - 2.00 per hr. for Cross-Bar and Hard Shoe Tracks, and about $4.00 per hr. for soft tracks. Q: Can I run metal tracks on a hard surface? A: Yes, The Grouser track was designed to run on a hard surface with minimal scratching. The exception is soft asphalt or other sensitive surfaces. Q: What are the reports from the field on the 1 ¼” bushing introduced in April of 1999? A: The E Series track design has more then exceeded our highest expectations. A: Customers comment of over 1000 hours and bushing replacement not needed. Q: What is the machine ground pressure with tracks? A: Tracks will reduce the ground pressure by about 50%. Example 16 psi with tires equals 8 psi with tracks. Q: Should the tracks be run loose or tight? A: The tracks should never be run tight. Running the tracks with about 1 ½” – 3” of sag is recom- mended. Q: When mounting tracks do I let the air out of the tires, mount track and inflate the tires? A: No, before mounting over the tire tracks, inflate the tire to manufactures recommended pressure and proceed to mount track as stated in the mounting instructions. Q: Will tracks work with solid, Air boss or foam filled tires? A: Loader manufactures do not recommend track use on non-pneumatic tires. For instance if a large object rotates around between the tire and track it can damage the loader due to the fact the tire is more rigid and will not compress like a pneumatic tire. Q: Do you ever need to modify the loader? A: Yes, any interference with the track such as fenders, buckets, and hoses must be addressed at the time of initial installation. Some interferences can be addressed with wheel spacers or boomstops avail- able from Grouser. Correcting some areas of interferences are the responsibility of the customer. Q: My customer is thinking of buying a new machine, will he be able to transfer the tracks from his old machine to the new one? A: Yes, as long as the tire size remains the same you can either add or subtract pad sections to match up to a machine with a different wheelbase. Q: What is the warranty on over the tire tracks systems? A: Two years from date of purchase on material and workmanship. Q: Why did Grouser go to induction hardening? A: Induction hardening will consistently double the life of the wear surface, for customer value and pro- ductivity. Any track that needs to be frequently rebuilt with a welder is time and cost prohibiting. The induction hardened Grouser track will outlast the life of the welded track with no need to do any welding.

Q: What has been the dealer / customer reaction to the Grouser Track? A: The Grouser Track was introduced in 1987 with 0% of the market and today has 2/3 of the market. Q: What has been the OEM reaction to the Grouser Track? A: Most OEM's have switched to the Grouser track on their skid loader. Track Fitting Q: Why do I need wheel spacers? A: Wheel spacers move the tire out to provide the required clearance so the track will not come into con- tact with the frame, boom or other parts of the loader. Q: How much wider will tracks make my machine? A: Tracks add 3 inches to the width of the machine, but if the machine requires wheel spacers be sure and add the thickness of the spacer. Q: What is the proper clearance needed for tracks? A: We recommend at least 2 inches of clearance around the tire and 2 ½ inches from the tire sidewall to frame of machine. Q: How much side clearance do I need between the tire and track pad? A: Track pad to tire clearance will vary from one tire manufacture to another. For best performance use a tire that fills the pad section well, but never use a tire that is being pinched by the track pad. This can cause premature sidewall tire wear. Parts Information Q: When I replace the bushings do I have to replace the links? A: No, replace the bushings once wear has reached the bolts. Replace links when the ends are worn thin and ready to break. A rule of thumb is you will replace 2 - 3 sets of bushings to each set of links. Q: How many nuts, bolts, bushing and links go into a set of tracks? A: Each pad section contains 4 nuts, 4 bolts, 4 bushings and 2 links Multiply by number of pad sections in track. Example a machine with 36 pads will require 144 nuts, bolts, bushings and 72 links. Trouble Shooting Q: Why are my wheel spacers studs breaking? A: Most likely the rim has come loose from the spacer or the spacer has come loose from the axle. To prevent problem mounting surfaces must be clean and wheel nuts torque to manufactures specifications and re-torque after 3-4 hours use. Properly installed spacers never give any trouble. Q: Why are my bolts worn and the bushings are not? A: The wear should be on the bushing O.D. if the bolt was not tightened properly the bushing will rotate on the bolt. This will cause direct wear to the bolt. This condition is not harmful simply retighten bolts. Q: What should I do when my tires start slipping inside the track? A: Tires should not slip inside the track so check for proper track tension, (1-½ inches of sag) if tension is correct check traction bars for wear and rebuild or replace if necessary. A very worn tire will not grip the tire properly.

GROUND PRESSURE COMPARISON
TRACK ATTACHMENTS
Ice & Traction Pick: The pick is designed to greatly increase traction on ice, frozen ground, hard ground or wherever extra traction is required. Picks can be installed or removed with the track mounted on the loader and need only be bolted to some of the pads.
Flotation Pad: There are some conditions in soft ground or sand that even a track can’t keep the loader from sinking. Because skid loaders are compact machines there is very little room to increase the foot print and reduce the ground pressure. Flotation plates can be bolted to the outside area of the pad to increase the footprint by 70%.

SOFT SHOE TRACK—FEATURES / BENEFITS The Grouser Soft Track was developed for those customers who have applications that require tracks but for various reasons cannot use metal tracks. The soft track will provide increased performance nearly equal to the metal track. Cost: What is most important to understand is that the cost to purchase and maintain the soft track will be much higher than the metal track. The higher cost is due mainly to the replacement of the shoes that are expensive to buy and are subject to rapid wear. Shoe Life: Wear life of the shoe is directly related to how it is used. Running the soft track on rough concrete, blacktop, rock or other abrasive surfaces will wear the shoe out in a very short time. Usually it means tires would not have lasted much longer under the same conditions. To get maximum life out of the track shoes, it is recommended that the tracks be run only when needed and that common sense be used when turning the loader to minimize shoe wear. Experience has shown that operator technique can greatly affect the life of the shoes, with customers reporting shoe life from 100—1000 hours. Under some conditions the shoes will wear uneven and must be rotated like tires to get maximum wear. Because shoe replacement is a major factor in cost per hour of running the soft track, the shoes are bolted on for easy replacement. They can even be replaced with the tracks left on the loader. Grouser is constantly testing new compounds to extend shoe life and bring down the cost of running the soft track. Traction Bar: The soft track cast pad contains two replaceable induction hardened traction bars and therefore may be replaced. Hardening of the traction bar eliminates the need to weld or “build up” the traction bar as is the case with other tracks on the market. Traction bar wear will vary according to con- ditions and operator technique. Space Requirements: Soft tracks take up slightly more space on the face of the tire than the metal track and therefore some loaders may need special consideration. E Series Soft Shoe has a new compound which has shown exceptional wear life and could equal the life of the tire in most conditions. The new shoe could reduce the cost of running the soft shoe track from $5-$6 to $3-$4 per hour. The new shoe is compatible with the older D series pad.

MARKET PROFILE—DOZER BLADE
Customer: The 1300 6 way dozer was designed to be used primarily with the 1500 pound and larger skid loader. The larger loaders are ideally suited with their longer wheelbase and heavier weight. Its primary cus- tomer is the contractor that utilizes the loader through the use of attachments to accomplish jobs that would otherwise require bringing other larger pieces of equipment to the job site. Since its introduction the 1300 dozer has experienced rapid growth as customers have come to realize its potential to save time and money. The dozer has established a high repeat order status, which is an ex- cellent indicator of its performance and acceptance. Application: The dozer is ideally suited to move loose material such as, spread fill material, level sand and gravel, back fill around foundations, back fill trenches, create run off trenches, remove rocks, push and pile snow, push and pile silage, build septic tank mounds, back dragging, and use with a laser for precise work. Equipping the loader with tracks for maximum traction can enhance the dozer performance. When dem- onstrating keep in mind that loose or mellow ground is best. Dozing in hard ground is possible but not as impressive. You also want to practice dozing before demonstrating as it takes some experience to doze effectively. Trends: The 7-foot dozer is the most popular width, with the 8-foot increasing in numbers, and the 6-foot stabiliz- ing. As with all attachments, the dozer is being recognized as a very effective performance tool with more customers finding uses for it. As dealers promote the dozer it will become another necessary attach- ment.

FEATURES / BENEFITS—DOZER BLADE
History: Grouser Products has been making dozers for rubber tire equipment up to 500 horsepower since 1978. The 1300 dozer was introduced in 2000 in response to customer demand for a heavy-duty 6-way dozer for the skid loader. Design: The dozer was designed to quick attach to the loader arms in place of the bucket. Dozing is performed with the loader arms against the stops to properly absorb the loads. The dozer is typically equipped with an electric diverter valve. This allows one set of loader couplers to perform two functions – tilt and angle. The dozer is typically shipped with tilt being the primary function and angle as a secondary function. By utilizing the loader’s electrical system the operator may cross be- tween functions by a simple push of a button while operating the auxiliary hydraulics.. A double crossover relief valve is an available option. which uses pressure to switch functions. When the tilt cylinder bottoms out, the oil is forced over the dozer relief valve and into the angle cylinders. The relief valve offers a unique safety feature in that if the dozer strikes an object hard enough to cause 2000 psi in the angle cylinders the oil will release over the relief valve and enter the tilt cylinder causing the end of the blade to rise and pass over the object. Features: • Exceptionally strong cast components carry limited 2 year warranty hydraulic components carry
a 1 year warranty • Cast design that is very strong and eye appealing • Cast design provides a cavity to protect the electric diverter valve • Cast design provides a full width safety step area • Cast design places the electric valve closer to the cylinders making hose routing efficient and neat • Cast design allows wear areas to be made thicker • Cast design incorporates a flush mounted 6” reversible cutting edge • Cast Female Quick Attach meets new SAE specs • Cast Moldboard has a new skid shoe design that allows vertical and horizontal adjustment Specifications: 1. Dozer quick attaches in place of the bucket. 2. Only one loader valve is needed to control both angle and tilt. 3. Approximate distance of cutting edge ahead of loader quick attach is 31". 4. Completion of both angle and tilt functions with a push of a button with the electric valve option. 5. Built in hydraulic safety tilt trip if pressure exceeds dozer valve setting in the relief valve option 6. Dozer weighs approximately the same as bucket full of dirt to achieve down pressure. 7. Cutting edge is 5/8 X 6 double bevel flat reversible bolt on. 8. Each adjustable skid shoe has 88 sq. in. of contact area. 9. Moldboard—5/16” thick x 24” high 10. Blade angles 0 to 30° left and right 11. Blade tilts 10° 12. Cast Blade widths from 6’, 7’ and 8’ 13. Angle Cylinders—4” x 8” with 2” Rods 14. Tilt Cylinder—4” x 8” with 2” Rods 15. Adjustable, rebuildable skid shoes—standard Parts: The only recommended parts are a seal kit. Keep in mind the all cylinders take the same kit and there- fore only one is needed. All other parts can readily be obtained from Grouser on short notice.

FREQUENTLY ASKED QUESTIONS—DOZER BLADE
Q: Is the 1300 model a heavy duty Six way Dozer? A: Yes, this is a very versatile unit with the tilt and angle functions built into the dozer. For strength the dozer is designed to push with the loader arms down against the stops and the bucket cylinders are used to control the cut (pitch). Q: How tall are the 1300 blade and what widths are available? A: 24 inches tall and 6-7-8-9 ft. available widths. Q: How wide a dozer should I have? A: You need to be about one foot wider then the machine so when the blade is angled it still covers the width of the machine. Remember that when a dozer is angled it moves off to the side the material is moving, this feature keeps the material away from the tire. Q: How does the loaders single hydraulic circuit control both angle and tilt? A: The unit comes standard with a relief valve that allows angle and tilt. The relief valve oil is routed di- rectly to the tilt cylinder. To set angle, the tilt cylinder is run fully in or out (for left or right angle) till it bot- toms out, the oil will be forced through the relief valve into the angle cylinders. This is convenient when the dozer is to be used on different loaders that are not wired for the optional electric valve. Q: Is there an option to the relief valve? A: Yes an optional electric diverter valve is available, which allows angle and tilt functions from one source of oil. This requires wiring the loader with a switch to control the electric valve. With the switch the machines standard controls be they hand, foot or electric control angle and tilt. A: The electric diverter valve option will allow the operator get more productive time out of the skid steer and dozer unit by being able to quickly switch from angle to tilt from the operators seat using familiar con- trols. Q: What types of jobs are best suited for the 1300 skid steer dozer? A: Leveling, piling, or grading dirt, gravel, or sand. It is fair to say that a large skid steer equipped with tracks and dozer can easily compete with a small crawler dozer in loose material. Q: How do I control my depth and level of cut? A: The 1300 dozer comes with adjustable skid shoes 3.5” x 18”. Also the use of the bucket cylinders to control the cut (pitch) provides for a finer adjustment than the boom cylinders can provide. Q: Should I have tracks on my skid steer along with the dozer what will be the benefits? A: The five main benefits are traction, flotation, tire protection, balance, and ride comfort. A: Increase the quantity of material you can push on each pass by providing increased traction. A: Provide ballast for a more stable dozing platform. A: It makes it easier to turn and maneuver. A: The unit will perform much like a small crawler dozer of the same weight. Q: Is the 1300 dozer recommended for pushing snow? A: It can be used for snow very effectively but remember it has no trip mechanism. Q: How long is the warranty on the 1300 dozer? A: 2 years on cast components, 1 year on hydraulic and electrical components. Q: What do I need to know to get the correct electrical hookup? A: The make and model and is there a factory electrical attachment control adapter on the machine.

E-Series Track &
Hard Shoe Track
Soft Shoe Track
WHY USE "OVER-THE-TIRE" TRACKS?
Traction: If a skid loader is not performing in adverse conditions it is usually because the loader has lost traction. The installation of tracks will greatly restore traction and loader performance.
Flotation: Flotation is a small but important part of loader performance. Tracks increase floatation by contributing to the following factors: (1) Ground Pressure/PSI Rating is reduced by the track laying down a larger footprint than the tire,
effectively reducing the ground pressure of the skid loader by as much as 50%. (2) Traction keeps the loader moving therefore not allowing it to have time to sink. (3) Time: By keeping the loader moving it prevents the loader from staying in one spot long enough to
sink. (4) Too much flotation and performance will disappear due to a loss of traction. This can easily happen
when psi gets down in the range of 3-4 psi.
Wear: Because tracks have less adhesion when turning on hard or abrasive surfaces, they can effectively re- duce tire costs in some conditions. Tracks can also reduce drive train wear by reducing the shock loading caused by the operator spinning the tires and reversing direction to maintain movement when the loader has lost traction.
Ride: Tracks can greatly increase ride comfort in rough terrain as they bridge the rough spots thus smoothing out the ride. The counterbalance weight of the track also helps carry heavy loads smoother and safer.
Cost: Track costs of $1.00 to $4.00 per hour can be very cost effective when considering they allow the loader to do work in conditions where tires cannot. Without tracks, other equipment would have to be brought in or operators would have to wait until conditions improve. The amount of increased production time that tracks return can add up to many times the cost of the tracks. Tracks, for the most part, can be left on year around as performance is increased even in good condi- tions. Tracks need only be removed if surface disturbance or damage is a consideration. These condi- tions can be addressed with the exclusive Grouser Soft Shoe Track.
Tire Protection: Tracks do a very good job of protecting the tender sidewall of the tire. They also have a protective quality at the face of the tire.
Turning: Because tracks create a lower ground pressure they will actually turn easier than tires in many condi- tions.
Conclusion: Tracks are the one attachment that can not only contribute to the performance of the loader but also im- prove the performance of other attachments that one may purchase for the machine and therefore con- tribute to profitability under many job applications.

MARKET PROFILE—OVER THE TIRE TRACKS
Customer profile: Approximately 50% of over-the-tire metal track sales come from the small contractor who uses their skid loader as the primary tool to make money. The second largest track market would be the landscape and nursery market with approximately 30%. The rest of the market would be made up of farmers with poultry or livestock, municipalities, large con- tractors, recycling, foundry, demolition, fertilizer, mining, woods, and other. Rental yards are a fast grow- ing segment in the track market with the introduction of the cost effective EX Combo soft track.
Identifying track customers: There is a potential customer for every loader that is experiencing excessive tire slippage. The most ob- vious conditions are mud and sand but tracks also enhance performance and smooth out the ride even in good conditions. So there are far more potential customers than one would think. Keep in mind if the tires are spinning the loader is not producing and is a potential customer.
Applications in which tracks help sell loaders: Landscaping, spread and level loose material, tree digging and transplanting, mining operations, prepar- ing job sites, moving construction material at job sites, barge and ship unloading, livestock operations, backfilling, working in peat bogs, fencing contractors, demolition, swimming pool installation and any ap- plication that traction, ride, tire protection, and/or floatation is a problem. The soft shoe track is targeted at the market with sensitive areas to work in.
Trends: We see the usage of tracks to continue to be strong with new applications being discovered because of their inherent advantages. Currently about 15% of the new loaders are utilizing tracks and that number is increasing as more people become aware of their advantages. The use of tracks tends to grow rapidly in the areas where the dealer promotes them.
Demonstration tips: Recognize an application to which the benefits of tracks could be appreciated. Many times the dealer thinks the loader doesn’t need any help because after all it is a four-wheel drive unit. He finds out too late that the loader had a poor showing because of a low traction condition, when in fact it was the right piece of equipment but not properly set up for the job. Some dealers have developed a very profitable attachment sale by demonstrating the loader with tracks. Once the customer sees the difference tracks make, they will usually order, even if they feel they will not need them all the time.

GROUSER TRACK—FEATURES / BENEFITS History Grouser over-the-tire tracks were developed over a 12 year period from 1975 to 1987 when the present design was finalized and introduced as the finest track available then and now. Up until 1991 the Grouser track was a hand welded track. In 1991 Grouser installed a robot to do the welding for rea- sons of quality and to keep up with demand. In 1993 Grouser took the ultimate step and switched to a cast pad and link. This improved the product with a better material that is stronger and yields a longer wear life. The Cross-Bar Track has even smoother edges for tire protection and a quality standard that no weldment can match. The Cross-Bar Metal Track is now available for the most popular tire sizes such as 10.00, 12.00, 14.00 and 15.5. In 1999 the Combo Track was introduced for those markets that need the versatility of a track. The Combo Track is an Over-The-Track that has replaceable pads. The re- placeable pads are available as a soft shoe or a steel shoe.
Design The Grouser run loose design was developed to provide maximum performance through flota- tion, traction, cleaning, and low cost per hour to own.
Traction Loss of traction is the number one performance robbing condition encountered by the skid loader. Traction is restored by the segmented design and large cross bars that can sink into the ground effectively controlling ground sheer. The segmented design allows material to squeeze up into the track and tire to prevent spinning by providing the maximum amount of material for the track and tire to push against. Even though the pads that lay between the tires do not significantly contribute to flotation, they play a very important part in maintaining traction by adding to the number of pads that have to be ground sheared.
Flotation The design of Grouser tracks correctly places the most pad area beyond the face of the tire where it belongs and effectively reduces the ground pressure of the skid loader by as much as 50%. Keep in mind that the tire will retain its original ground contact area without any help from the design of the track pad. The area between the tires does not help in reducing ground pressure as can be demon- strated at any time by the ability to pick up the pads between the tires with your hand. Flotation between the wheels can be accomplished only by applying force from the opposite side (such as with rollers). Since there is no down force between the wheels, flotation cannot be accomplished in this area.
Cleaning A high performance track must clean well to perform well. Cleaning is a direct result of the open, segmented pad design that lets material pack in for traction and flotation but allows the material to be ejected by the action of the tire against the material as the tire rotates. The Grouser track utilizes two methods of cleaning. The first is the natural dumping of material as the track sections open and close as they rotate around the tire. The second is the action of the tire against the face of each pad.
Ride Ride is controlled by the equal height and equal spaced pad sections. This ensures that both the front tire that lays down the track and the rear tire that runs over it see the same smooth surface.
Tire Protection and Guidance The track protects the tire sidewall with very large smooth tire guides that will not cut or injure the tire. The tire guides also prevent the track from coming off even though it is run loose.
Rebuildable The nuts, bolts, bushings, links, traction inserts and shoes can all be field replaced using a 3/4” or 9/16” wrench.
Pivot Bushings and Links Bushings for all series of tracks are heat treated to provide maximum wear. The links for all tracks are cast from the same high quality material as the pads. The bushing is locked in the pad so all wear is between the replaceable bushing and link.
Replacement Parts Even though the Grouser track fits small to large tires it was designed with in- ventory and ease of service in mind. Consider that all series A, B, C, D and E tracks produced since 1987 use the same nut & bolt. If replacing links on the older series tracks, one could always upgrade to a 1” size. The E-Series track is now in a class by itself and requires a 1 1/4” bushing and new link de- sign. On the Combo Track the hard and soft shoes are bolt on replaceable as well as the drop in trac- tion inserts.

Track Tension Over-the-tire tracks require slack just like sprocket driven tracks. The Grouser pad is designed to grip the tire not with tension but with contact with the face of the tire. The design does, how- ever, compensate for different tire sizes by allowing the tire to reposition as it rolls into the track. The loader can be driven forever in one direction and the slack will never leave the top and tighten the track.
Weight For the sake of flotation it would be nice to have a light track but experience has proven that the weight has far more advantages than disadvantages. The weight is a direct result of the track being strong and long wearing. The added weight also provides counterbalance to help carry heavy loads safer and sometimes makes it unnecessary to add optional weight kits.
Track Height Track pad height raises the loader up higher than the tires resulting in a different bucket angle and slightly faster travel speed. Here again experience proves that the bucket angle with tracks in the mud and other soft material is not noticeable and the limiting height in most cases is the clearance required to run the track. To keep the track height to a minimum Grouser utilizes approximately a 1.3- inch high pad to provide the maximum amount of material to be worn away in the smallest possible area.
Length Adjustment All tracks must have a method to adjust for length due to different tire sizes, wheelbase and wear. The Grouser track utilizes a very simple method by having available in every pad a long and short hole. This means that every pad is an adjuster pad and the track can be adjusted for length indefinitely.
Installation The track is easy to mount by laying it out, driving the loader on and bringing the ends together over the top between the tires. The ends are pulled together with the web binder provided. With experience, the tracks can be mounted in 30 minutes and dismounted in 10 minutes.
Wheel Spacers It is just as important to provide the proper clearance to the machine as it is to pro- vide the proper track for the loader. A variety of spacers are available in different thickness and diame- ters to accommodate all of the loaders on the market today. All 6 on 6 and 8 on 8 wheel spacers now include male and female pilots for the axle and rim to set on which relieves the studs from carrying all the weight and thus sometimes coming loose.
Cost To provide the finest product is always our goal and to do it at an acceptable cost to the customer can be even more difficult but due to the very efficient nature of the Grouser design, cast construction and the sales volume, it can be marketed at a cost that is extremely competitive if not the lowest avail- able. For example the cost per pound for the 13234-3E track is only $2.41, with the cost per hour to run averaging between $1 - $2. The soft shoe track can run $3 - $4 per hour.
Distribution Grouser tracks are sold and serviced through authorized dealers and OEM agreements in the US and Canada. Grouser also distributes tracks in other parts of the world through distributors and OEM agreements.
References User and dealer references are available on request.
Literature All literature is available upon request along with sample pads to show customers.
Parts The track comes with two extra nuts, bolts and bushings to replace the occasional lost one. The track generally does not need replacement parts until wear demands it and they are readily available from Grouser on short notice.
Warranty The standard Grouser track limited warranty is 2 years against material and workmanship. Wear, abuse, performance and fit are not covered.

FREQUENTLY ASKED QUESTIONS—TRACKS Sales Information Q: Why should I use tracks? A: Even though skid loaders are a great versatile work horse they frequently loose traction in many condi- tions. Tracks do an excellent job of restoring machine performance especially in the areas of traction, flotation, weight balance, tire life and drive system life. Q: How long should the tracks last? A: To give an exact life of a track is not realistic – soil abrasion –machine weight – and operator tech- niques dictate the length of life. We have reports of tracks running in excess of 3000 hours with minimal bushing and link replacement. Cost per hour on usage is about $1.00 - 2.00 per hr. for Cross-Bar and Hard Shoe Tracks, and about $4.00 per hr. for soft tracks. Q: Can I run metal tracks on a hard surface? A: Yes, The Grouser track was designed to run on a hard surface with minimal scratching. The exception is soft asphalt or other sensitive surfaces. Q: What are the reports from the field on the 1 ¼” bushing introduced in April of 1999? A: The E Series track design has more then exceeded our highest expectations. A: Customers comment of over 1000 hours and bushing replacement not needed. Q: What is the machine ground pressure with tracks? A: Tracks will reduce the ground pressure by about 50%. Example 16 psi with tires equals 8 psi with tracks. Q: Should the tracks be run loose or tight? A: The tracks should never be run tight. Running the tracks with about 1 ½” – 3” of sag is recom- mended. Q: When mounting tracks do I let the air out of the tires, mount track and inflate the tires? A: No, before mounting over the tire tracks, inflate the tire to manufactures recommended pressure and proceed to mount track as stated in the mounting instructions. Q: Will tracks work with solid, Air boss or foam filled tires? A: Loader manufactures do not recommend track use on non-pneumatic tires. For instance if a large object rotates around between the tire and track it can damage the loader due to the fact the tire is more rigid and will not compress like a pneumatic tire. Q: Do you ever need to modify the loader? A: Yes, any interference with the track such as fenders, buckets, and hoses must be addressed at the time of initial installation. Some interferences can be addressed with wheel spacers or boomstops avail- able from Grouser. Correcting some areas of interferences are the responsibility of the customer. Q: My customer is thinking of buying a new machine, will he be able to transfer the tracks from his old machine to the new one? A: Yes, as long as the tire size remains the same you can either add or subtract pad sections to match up to a machine with a different wheelbase. Q: What is the warranty on over the tire tracks systems? A: Two years from date of purchase on material and workmanship. Q: Why did Grouser go to induction hardening? A: Induction hardening will consistently double the life of the wear surface, for customer value and pro- ductivity. Any track that needs to be frequently rebuilt with a welder is time and cost prohibiting. The induction hardened Grouser track will outlast the life of the welded track with no need to do any welding.

Q: What has been the dealer / customer reaction to the Grouser Track? A: The Grouser Track was introduced in 1987 with 0% of the market and today has 2/3 of the market. Q: What has been the OEM reaction to the Grouser Track? A: Most OEM's have switched to the Grouser track on their skid loader. Track Fitting Q: Why do I need wheel spacers? A: Wheel spacers move the tire out to provide the required clearance so the track will not come into con- tact with the frame, boom or other parts of the loader. Q: How much wider will tracks make my machine? A: Tracks add 3 inches to the width of the machine, but if the machine requires wheel spacers be sure and add the thickness of the spacer. Q: What is the proper clearance needed for tracks? A: We recommend at least 2 inches of clearance around the tire and 2 ½ inches from the tire sidewall to frame of machine. Q: How much side clearance do I need between the tire and track pad? A: Track pad to tire clearance will vary from one tire manufacture to another. For best performance use a tire that fills the pad section well, but never use a tire that is being pinched by the track pad. This can cause premature sidewall tire wear. Parts Information Q: When I replace the bushings do I have to replace the links? A: No, replace the bushings once wear has reached the bolts. Replace links when the ends are worn thin and ready to break. A rule of thumb is you will replace 2 - 3 sets of bushings to each set of links. Q: How many nuts, bolts, bushing and links go into a set of tracks? A: Each pad section contains 4 nuts, 4 bolts, 4 bushings and 2 links Multiply by number of pad sections in track. Example a machine with 36 pads will require 144 nuts, bolts, bushings and 72 links. Trouble Shooting Q: Why are my wheel spacers studs breaking? A: Most likely the rim has come loose from the spacer or the spacer has come loose from the axle. To prevent problem mounting surfaces must be clean and wheel nuts torque to manufactures specifications and re-torque after 3-4 hours use. Properly installed spacers never give any trouble. Q: Why are my bolts worn and the bushings are not? A: The wear should be on the bushing O.D. if the bolt was not tightened properly the bushing will rotate on the bolt. This will cause direct wear to the bolt. This condition is not harmful simply retighten bolts. Q: What should I do when my tires start slipping inside the track? A: Tires should not slip inside the track so check for proper track tension, (1-½ inches of sag) if tension is correct check traction bars for wear and rebuild or replace if necessary. A very worn tire will not grip the tire properly.

GROUND PRESSURE COMPARISON
TRACK ATTACHMENTS
Ice & Traction Pick: The pick is designed to greatly increase traction on ice, frozen ground, hard ground or wherever extra traction is required. Picks can be installed or removed with the track mounted on the loader and need only be bolted to some of the pads.
Flotation Pad: There are some conditions in soft ground or sand that even a track can’t keep the loader from sinking. Because skid loaders are compact machines there is very little room to increase the foot print and reduce the ground pressure. Flotation plates can be bolted to the outside area of the pad to increase the footprint by 70%.

SOFT SHOE TRACK—FEATURES / BENEFITS The Grouser Soft Track was developed for those customers who have applications that require tracks but for various reasons cannot use metal tracks. The soft track will provide increased performance nearly equal to the metal track. Cost: What is most important to understand is that the cost to purchase and maintain the soft track will be much higher than the metal track. The higher cost is due mainly to the replacement of the shoes that are expensive to buy and are subject to rapid wear. Shoe Life: Wear life of the shoe is directly related to how it is used. Running the soft track on rough concrete, blacktop, rock or other abrasive surfaces will wear the shoe out in a very short time. Usually it means tires would not have lasted much longer under the same conditions. To get maximum life out of the track shoes, it is recommended that the tracks be run only when needed and that common sense be used when turning the loader to minimize shoe wear. Experience has shown that operator technique can greatly affect the life of the shoes, with customers reporting shoe life from 100—1000 hours. Under some conditions the shoes will wear uneven and must be rotated like tires to get maximum wear. Because shoe replacement is a major factor in cost per hour of running the soft track, the shoes are bolted on for easy replacement. They can even be replaced with the tracks left on the loader. Grouser is constantly testing new compounds to extend shoe life and bring down the cost of running the soft track. Traction Bar: The soft track cast pad contains two replaceable induction hardened traction bars and therefore may be replaced. Hardening of the traction bar eliminates the need to weld or “build up” the traction bar as is the case with other tracks on the market. Traction bar wear will vary according to con- ditions and operator technique. Space Requirements: Soft tracks take up slightly more space on the face of the tire than the metal track and therefore some loaders may need special consideration. E Series Soft Shoe has a new compound which has shown exceptional wear life and could equal the life of the tire in most conditions. The new shoe could reduce the cost of running the soft shoe track from $5-$6 to $3-$4 per hour. The new shoe is compatible with the older D series pad.

MARKET PROFILE—DOZER BLADE
Customer: The 1300 6 way dozer was designed to be used primarily with the 1500 pound and larger skid loader. The larger loaders are ideally suited with their longer wheelbase and heavier weight. Its primary cus- tomer is the contractor that utilizes the loader through the use of attachments to accomplish jobs that would otherwise require bringing other larger pieces of equipment to the job site. Since its introduction the 1300 dozer has experienced rapid growth as customers have come to realize its potential to save time and money. The dozer has established a high repeat order status, which is an ex- cellent indicator of its performance and acceptance. Application: The dozer is ideally suited to move loose material such as, spread fill material, level sand and gravel, back fill around foundations, back fill trenches, create run off trenches, remove rocks, push and pile snow, push and pile silage, build septic tank mounds, back dragging, and use with a laser for precise work. Equipping the loader with tracks for maximum traction can enhance the dozer performance. When dem- onstrating keep in mind that loose or mellow ground is best. Dozing in hard ground is possible but not as impressive. You also want to practice dozing before demonstrating as it takes some experience to doze effectively. Trends: The 7-foot dozer is the most popular width, with the 8-foot increasing in numbers, and the 6-foot stabiliz- ing. As with all attachments, the dozer is being recognized as a very effective performance tool with more customers finding uses for it. As dealers promote the dozer it will become another necessary attach- ment.

FEATURES / BENEFITS—DOZER BLADE
History: Grouser Products has been making dozers for rubber tire equipment up to 500 horsepower since 1978. The 1300 dozer was introduced in 2000 in response to customer demand for a heavy-duty 6-way dozer for the skid loader. Design: The dozer was designed to quick attach to the loader arms in place of the bucket. Dozing is performed with the loader arms against the stops to properly absorb the loads. The dozer is typically equipped with an electric diverter valve. This allows one set of loader couplers to perform two functions – tilt and angle. The dozer is typically shipped with tilt being the primary function and angle as a secondary function. By utilizing the loader’s electrical system the operator may cross be- tween functions by a simple push of a button while operating the auxiliary hydraulics.. A double crossover relief valve is an available option. which uses pressure to switch functions. When the tilt cylinder bottoms out, the oil is forced over the dozer relief valve and into the angle cylinders. The relief valve offers a unique safety feature in that if the dozer strikes an object hard enough to cause 2000 psi in the angle cylinders the oil will release over the relief valve and enter the tilt cylinder causing the end of the blade to rise and pass over the object. Features: • Exceptionally strong cast components carry limited 2 year warranty hydraulic components carry
a 1 year warranty • Cast design that is very strong and eye appealing • Cast design provides a cavity to protect the electric diverter valve • Cast design provides a full width safety step area • Cast design places the electric valve closer to the cylinders making hose routing efficient and neat • Cast design allows wear areas to be made thicker • Cast design incorporates a flush mounted 6” reversible cutting edge • Cast Female Quick Attach meets new SAE specs • Cast Moldboard has a new skid shoe design that allows vertical and horizontal adjustment Specifications: 1. Dozer quick attaches in place of the bucket. 2. Only one loader valve is needed to control both angle and tilt. 3. Approximate distance of cutting edge ahead of loader quick attach is 31". 4. Completion of both angle and tilt functions with a push of a button with the electric valve option. 5. Built in hydraulic safety tilt trip if pressure exceeds dozer valve setting in the relief valve option 6. Dozer weighs approximately the same as bucket full of dirt to achieve down pressure. 7. Cutting edge is 5/8 X 6 double bevel flat reversible bolt on. 8. Each adjustable skid shoe has 88 sq. in. of contact area. 9. Moldboard—5/16” thick x 24” high 10. Blade angles 0 to 30° left and right 11. Blade tilts 10° 12. Cast Blade widths from 6’, 7’ and 8’ 13. Angle Cylinders—4” x 8” with 2” Rods 14. Tilt Cylinder—4” x 8” with 2” Rods 15. Adjustable, rebuildable skid shoes—standard Parts: The only recommended parts are a seal kit. Keep in mind the all cylinders take the same kit and there- fore only one is needed. All other parts can readily be obtained from Grouser on short notice.

FREQUENTLY ASKED QUESTIONS—DOZER BLADE
Q: Is the 1300 model a heavy duty Six way Dozer? A: Yes, this is a very versatile unit with the tilt and angle functions built into the dozer. For strength the dozer is designed to push with the loader arms down against the stops and the bucket cylinders are used to control the cut (pitch). Q: How tall are the 1300 blade and what widths are available? A: 24 inches tall and 6-7-8-9 ft. available widths. Q: How wide a dozer should I have? A: You need to be about one foot wider then the machine so when the blade is angled it still covers the width of the machine. Remember that when a dozer is angled it moves off to the side the material is moving, this feature keeps the material away from the tire. Q: How does the loaders single hydraulic circuit control both angle and tilt? A: The unit comes standard with a relief valve that allows angle and tilt. The relief valve oil is routed di- rectly to the tilt cylinder. To set angle, the tilt cylinder is run fully in or out (for left or right angle) till it bot- toms out, the oil will be forced through the relief valve into the angle cylinders. This is convenient when the dozer is to be used on different loaders that are not wired for the optional electric valve. Q: Is there an option to the relief valve? A: Yes an optional electric diverter valve is available, which allows angle and tilt functions from one source of oil. This requires wiring the loader with a switch to control the electric valve. With the switch the machines standard controls be they hand, foot or electric control angle and tilt. A: The electric diverter valve option will allow the operator get more productive time out of the skid steer and dozer unit by being able to quickly switch from angle to tilt from the operators seat using familiar con- trols. Q: What types of jobs are best suited for the 1300 skid steer dozer? A: Leveling, piling, or grading dirt, gravel, or sand. It is fair to say that a large skid steer equipped with tracks and dozer can easily compete with a small crawler dozer in loose material. Q: How do I control my depth and level of cut? A: The 1300 dozer comes with adjustable skid shoes 3.5” x 18”. Also the use of the bucket cylinders to control the cut (pitch) provides for a finer adjustment than the boom cylinders can provide. Q: Should I have tracks on my skid steer along with the dozer what will be the benefits? A: The five main benefits are traction, flotation, tire protection, balance, and ride comfort. A: Increase the quantity of material you can push on each pass by providing increased traction. A: Provide ballast for a more stable dozing platform. A: It makes it easier to turn and maneuver. A: The unit will perform much like a small crawler dozer of the same weight. Q: Is the 1300 dozer recommended for pushing snow? A: It can be used for snow very effectively but remember it has no trip mechanism. Q: How long is the warranty on the 1300 dozer? A: 2 years on cast components, 1 year on hydraulic and electrical components. Q: What do I need to know to get the correct electrical hookup? A: The make and model and is there a factory electrical attachment control adapter on the machine.
