Optional Rollers and Bearing Available:

Some customers in specialized applications have requested an option be made available thatwould allow them to use rollers with round shafts and bearings with open housings. If the customerspecifically request this, the parts that will be needed are as follows:

Part No. Qty Description107178 1 a/r Roller with Round Shaft 88"107177 1 a/r Roller with Round Shaft 74"702485 2 Bearing and Housing Asy, for 74" or 88" (bearing Only P/N 703574)

These parts will bolt up in place of the current parts. There are no plans for a whole good optionfor the round shaft rollers and bearings

NOTE:This is for information only. There is no allowance for warranty, labor or shipping charges to make

this change. This option should only be used for customers that consider roller bearings as "throw away",expendable items and that have an exceptional maintenance program. These are typically high usagemachines such as turf farms. It is believed that other applications would benifit by using the currentstandard hex shaft design.

Models: All Flail Cuttershafts Date:May 8, 1995

Bulletin No:050895-1(old # 5895-1)


Cutter Shaft Material Wrapping, Causes and Effects:

Wrapping is a condition where the grass or other growth being mowed will wrap around thecuttershaft instead of being cut and mulched. This condition is caused by the cuttershaft speed beingtoo slow.

Different grasses, vines etc. cut differently and require different minimum speeds of thecuttershaft to keep it clear and free from wrapping. Tough fibrous growths are the hardest to cut withoutencountering wrapping and in some instances may require more than the normal cuttershaft speed of2000 RPM. Usually 2000 RPM cuttershaft speed is enough to cut cleanly without wrapping.

The cuttershaft speed may be too slow just because the tractor engine speed (in case of the self-powered models) is being operated throttled back. The solution in such situations is to increase thethrottle to recommended settings and drop to a lower ground speed gear. (See operating instructions forthe particular model involved)

The Cuttershaft speed may also be too low if not enough power is available to do the job. If themower is taken into a cut too tough for the power available, the cuttershaft speed will drop. If the speedgets too low, the material will start to wrap. The wound up grass will form a big wad at the end of thecuttershaft pressing against the cutter housing end plate. This wad will act like a big friction brake. It canbecome so tight that it will be impossible to turn the cuttershaft without first cutting away the wad. Sucha wad naturally causes the mower to pull hard. This is a situation where a lack of power is actually causinga need for more power.

So much heat can be generated by a wad wrapped around the end of the cuttershaft that thebearing will actually turn blue from the heat. Naturally, such heat will destroy the bearings and seals andresult in bearing failure. Even if the bearing does not fail it may get hot enough to melt the grease in thebearing housing. Once the grease is gone (it can happen as little as 15 minutes), there is nothing to keepthe bearing from burning up due to a lack pf lubrication even though the bearing was just greased. Thetype grease recommended for hammer Knife mower bearings has a high temperature (Bulletin No. 3dated 7/21/56) has a high temperature melting point and will stay with bearing under adverse conditionslonger than ordinary greases. Bearings which fail because of above mentioned conditions are notdefective in material or workmanship, and are not covered by warranty.

Models: All Flails Mowers using Mott Flail Knives Date:May 8, 1995

Bulletin No:050895(old # 5895-2)

Electric Flail Knife Grinder:The Mott (Alamo Industrial) Knife grinder P/N 702321, will sharpen all Mott Knives. The

Grinder is shipped complete and ready to use. A word of caution about electrically powered tools:Never use this grinder or any other power toll while standing on a wet surface, even though thegrinder has a grounded plug. Always wear and use all Safety Equipment when using power tools.

The grinder is easy to use. Following is suggested method to use when sharpening MottFlail Knives with the Mott Flail Knife Grinder/Sharpener.1. Support all Heads with stands, Do Not get under any object only supported by hydraulic

system or a hoist. Secure Tractor so it cannot be started by anyone.2. Position the mower so knives are easily accessible and mower is well supported by stands.3. Prevent the Cuttershaft from rotating, this can be done by clamping a bar to knife lugs and

other end of bar to deck.4. Determine which edges should be sharpened, top or bottom. Forward rotation mowers cut

with the rear (Bottom) edge of the knife. Reverse rotation mowers cut with the front (Top)edge of knife. It is necessary to sharpen the edge that is used.

5. Choose proper end and side of grinder. Match the illustration on the grinder with thedirection the knife tip points, as you face it. Note: Keep in mind which edge is to besharpened. If the tip points left, hold the grinder in the left hand, If the tip points right, holdthe grinder in the right hand. Note: Refer to Figure 2 for steps 5 & 6.

6. Use your free hand to hold the knife out away from the cuttershaft. Move the grinder so thatthe knife is inserted into the curved slot. Move the grinding wheel to put light pressure onthe knife edge. Move the grinder back and forth, grinding more at the tip of the knife. Note:Refer to Figure 2 for steps 5 & 6.

7. Sharpen the knives in that row which faces the same direction. Note: after severalsharpenings the knife should be tapered not notched.

8. Reverse the grinder to the use other slot to sharpen in same row which face the oppositedirection.

9. Rotate cuttershaft and repeat procedure for other rows of knives until all knives aresharpened.

Bulletin No: 032300

Alamo Industrial current production cuttershafts and bearings of all Interstater and Versa Flailmowers now utilize a slightly extended shaft and external locking outer bearing which utilizes twosetscrews.

This is an update to the previous bearing arrangement which provided one locking setscrewbehind the bearing located in a keyway machined in the cuttershaft stub (shaft end). This update wasinitiated in an effort to improve the maintenance procedures and ensure positive retention of the bearingto the cuttershaft.

The Old style Bearing (P/N 002315) one setscrew - bearing insert will be available for a limitedtime as supplies last. Replacement of the old (shorter) cuttershaft will require an updated to the longer

shaft and the replacement of thecuttershaft bearings to the new de-sign bearing (P/N 002530). Futurecuttershaft production will eliminatethe keyway required for the old bear-ing design. All cuttershaft part num-bers will remain unchanged.

When installing the newbearing it is important that the set-screws are designed to grip ontothe radius of the shaft. DO NOTinstall the setscrews onto a flat por-tion or machined groove which maybe on the shaft surface. Some up-dated longer shafts may incorpo-rate a keyway groove. When install-ing the new bearing on these shafts,the keyway should be ignored. Thenew bearing will not fit on an oldshaft at all, the shaft is to short. Figure 1

Possible Bearing Greaseability Problem: (Flail Head Only)Subject:

Roller bearing assembly; Seal Master brand Bearings Only. Correct possible greaseabilityproblem.Service Required:

Remove roller assembly from mower head. Check to see that the set screws are secure andholding the bearing assemblies to the roller. Check to see that the locking pin is holding bearing race inplace. This is done by pivoting the bearing housing to the left and right while attached to the roller.Excessive play indicates that the race is not being held in place. Rotate grease fitting into bearing housinguntil fitting bottoms out. Check bearing again for excessive play. Check to see if bearing will acceptgrease. If both test are passed the locking pin is holding the race in place. Position the grease fitting asshown in figure 1. If grease fitting must be loosened in order to achieve this, it should not exceed 1/2 turn.If you have any questions contact Alamo Industrial technical service dept.
