2.2. Intended use of the ORKAN VARIO plough

The ORKAN VARIO plough is designed to plough soils containing few stones. Its purpose is to cut up field’s earth, lift and turn it over in order to cover over crop residue and to loosen the soil. Its working elements are right- and left-hand plough bodies equipped with “18” shares, reversible chisels, and full half-screw or openwork cylindrical mouldboard Table 2. Description of the individual working components of the ORKAN VARIO plough.

Full half-screw mouldboard

Recommended for medium and light soils. Ideal for covering over crop residues and characterized by a low soil loosening intensity. It creates a wide furrow, which allows it to be used in cooperation with tractors having wide tires.

Openwork cylindrical mouldboard

Recommended for heavy (compacted) soils. Ideally loosens the soil and thanks to the mouldboard being of an openwork structure, ploughing resistance is reduced.

Scraper (trash board)

Provides good coverage of crop residues and organic fertilizers. Allows for a large space to be maintained between the plough bodies.

Skim coulter

Recommended for efficient deep ploughing on soils with a large amount of crop residues and stubble (especially corn for medium to shallow ploughing) and organic fertilizers

8

Gauge wheel

Shin

The rolling coulter is mounted on the end pair of plough bodies to ensure a suitable furrow shape. It puts up lower operating resistances compared to the knife cut form of ploughing.

This ensures furrow depth is maintained and longitudinal ploughing to ensure uniform depth of the furrow, regardless of surface irregularities.

This ensures correct arrangement of the furrow especially during the ploughing of stubble and areas covered by sod.

9

Rolling coulter

Alternative to the rolling coulters when reduction of mass is necessary. It is also recommended for large quantities of crop residues, organic fertilizers or stony soils when a rolling coulter would be blocked

WARNING! This plough is exclusively intended for agricultural work - soil cultivation. Using it for other purposes will be construed as improper use and will result in loss of warranty.

WARNING! The manufacturer is not responsible for damage caused by misuse of the machinery. Failure to comply with the instruction manual will also be construed as misuse.

3 General safety precautions The plough can only be started, used and repaired by persons familiar with its

operation and that of the tractor being used and the rules for its safe use and operation.The manufacturer will not be responsible for any arbitrary modifications of the construction of the plough. Only “MANDAM” factory parts should be used during the warranty period.The plough should be operated with caution and in particular:

• Before starting each ploughing operation, check the plough and the tractor whether their condition guarantees safety during operation and travel,

• It is forbidden for the agricultural machinery to be used by a minor, anyone sick, or after drinking alcohol or using other intoxicants,

• During work on this plough, one should use appropriate clothing, footwear and work gloves,

• Do not exceed the permissible axle loads, tire pressures or transport dimensions,• Only original pins and cotters should be used,• Do not approach the plough while it is being lifted or lowered,• Do not stand between the tractor and the plough when the engine is running,• Driving the agricultural machinery, or raising and lowering it must be performed

slowly and gently without violent jerks, making sure that no bystanders are close to the machinery,

• Do not reverse the tractor or make turns when the agricultural machinery is lowered into the operating position,

10

Coulter

• Do not use the tractor’s independent brakes while making turns,• Do not stand on the agricultural machinery or add any additional loads when it is in

operation or being transported,• Take special care when making turns if bystanders are close by,• Do not operate the plough on inclinations greater than 12º,• Only make repairs, lubricate or clean the working parts with the tractor engine

turned off and the plough lowered,• Do not carry out maintenance or replacement of parts beneath the agricultural

machinery without proper protection, as head injuries may occur - use a hardhat,• During breaks in its operation the agricultural machinery should be lowered to the

ground and the tractor engine turned off,• The plough is equipped with a mechanical lock that blocks the plough’s uncontrolled

rotation during transport,• Driving and parking this machine on sloping unstable ground may lead to its slipping,• Maintain the agricultural machinery in a manner that prevents injury to humans and

animals.

3.1. Hitching and unhitching to a tractor

• Make sure that the plough is connected to the tractor in accordance with the instructions, remembering to secure the bolts and that the bolts are secured with cotter pins.

• During towing of the plough by tractor it is forbidden to get between the agricultural machinery and the tractor.

• The tractor working with the plough must be fully operational. It is prohibited to connect this piece of machinery with a tractor with a hydraulic system that is not fully operative.

• One must remember to keep the tractor’s balance with the plough and maintain its steering and braking ability - the front axle load must not fall below 20% of the total axle load of the tractor – use the set of front end counterweights.

• In a resting position, the agricultural machinery should maintain a stable equilibrium and be disconnected from the tractor.

• The plough’s support stand should rest on stable ground. It is forbidden to use pads under the support as this may cause instability.

3.2. Tyres

• The tyre pressure must not exceed the tyre manufacturer’s recommended tyre pressure rating (as indicated on the tyre wall).

• Badly damaged tyres (especially damage to the profile) must be replaced immediately.

• Repair work on wheels or tyres should be carried out by trained and authorized personnel. These jobs should be carried out using appropriately selected tools.

11

lock lever

3.3. Hydraulic system

The hydraulic system works under high pressure. All precautions must be taken and in particular:

• Do not connect or disconnect hydraulic lines when the hydraulic system of the tractor is under pressure (hydraulics set to neutral).

• Regularly check the condition of connections and hydraulic lines,• When repairing any hydraulic breakdown, the plough should be disconnected from

its power source.

3.4. Transport on public roads

For transporting the plough, it should be turned to the middle position (the frame should be on the same axis as the tractor), then locked with the bolt. Prior to being rotated, lift the plough to a level where it will not come into contact with the ground. During transportation, the clearance under the lowest part of the plough should prevent it from coming into contact with the ground during transportation on uneven surfaces. When taking the plough onto public roads, it is mandatory to use driving lights, a distinctive warning sign and side reflectors.Do not exceed the appropriate speed limits during transportation, which are:

• up to 20 km/h on roads with smooth asphalt surfaces • 6-10 km/h on country roads or cobblestones • not more than 5 km/h on bumpy roads

The driving speed must be adjusted to the road conditions and conditions prevailing on the road so that the plough does not jerk the tractor’s suspension system and there is no excessive load on the plough’s frame or tractor’s suspension.Take special precautions when passing other vehicles, overtaking, and turning. The permissible width of the agricultural machinery moving on public roads is 3.0 m.It is forbidden to transport the plough over any area where the inclination of the slope transversely to the plough exceeds 7º.Be aware of the length of the plough. On sharp turns the plough turns in the opposite direction to the direction of the turn. This may result in a collision with obstacles or other road users.

During transport the plough is to be secured with the lock that keeps the plough on the same axis as the tractor, reducing its transport width and increasing the stability of the vehicle during transport. For locking, use the lever that you need to turn so that it jumps out of its slot and so that the pin holds the tow bar head in the locked position. Once locked, the plough cannot be turned because damage to it may occur. To unlock, turn the lock lever so that it falls back into its slot.

12

support standsafety pin

When the plough is parked, the support stand must be secured to stop the plough overturning. To this end, pull the safety pin, then take hold of the support stand’s handle and pull it toward you. Turn the support stand to the support position (a 90º rotation) and release the handle.

WARNING! Take care when transporting the plough. It is forbidden to travel on public roads without appropriate additional warning signs.

Thoroughly clean the agricultural machinery of all crop residues and earth before travelling on a public road. Portable warning lights and a distinctive warning sign for slow-moving vehicles (according to current traffic regulations) should be mounted on the end of the plough’s frame.

During transportation the plough should be raised to such a height that the minimum clearance under the agricultural machinery is a minimum 25 cm.

WARNING! Moving this plough on public roads without warning signs and lights required by the traffic regulations may be dangerous and cause an accident.

WARNING! Warning signs and lights are not part of the plough’s equipment. You can purchase them at points of sale for agricultural machinery.

Warning! Failure to adhere to the above may present a risk to the operator and bystanders, as well as cause damage to the agricultural machinery. Any damage resulting from non-compliance with these rules is the responsibility of the user.

13

3.5. Description of residual risk

MANDAM sp. z o.o. makes every effort to eliminate the risk of accident. However, there is a degree of residual risk that may cause an accident. The greatest danger occurs when:

• using the agricultural machinery for purposes other than those described in the instruction manual,

• the agricultural machinery is used by minors without permission, by anyone that is sick, or under the influence of alcohol or other intoxicants,

• people or animals come too close to the agricultural machinery,• insufficient care is taken when transporting and manoeuvring with the tractor,• anyone gets between the agricultural machinery and the tractor while the tractor’s

engine is running,• the plough is in operation or when its instruction manual are ignored,• travelling on public roads.

3.6. Residual risk assessment

Residual risks can be minimized by following the recommendations below:• careful operation of the agricultural machinery without undue haste,• careful reading of the instruction manual, • maintaining a safe distance from hazardous areas,• adhering to the rule about not riding on the agricultural machinery or coming too

close to the moving parts of the agricultural machinery while the tractor engine is running,

• performing all maintenance work in accordance with the safety precautions,• using protective clothing and, if any work needs carried out beneath the agricultural

machinery, wearing of a hardhat,• preventing unauthorized access to this piece of machinery, especially children.

0-10 cm greater than the rear tyres

4 Plough and tractor settingsThe tractor selected for use with this plough should have the characteristics described in the following paragraphs. The hydraulic system must be efficient and have two pairs of hydraulic couplings in accordance with ISO 7241-1 A, controlled by a twin distributor. The pressure in both rear tyres of the tractor should be the same value to avoid the formation of uneven ridges.

Recommendations for the tractor:• The recommended distance between the far inner

points of the rear tyres (without the use of a furrow extender) should be 120 - 160 cm,

• The recommended distance between the far inner points of the front tyres should be 0 - 10 cm greater than for the rear tyres

WARNING! The permissible loads on the axles and tyre load capacities must not be exceeded. The front axle load may not be less than 20% of total axle loads.

4.1. Preparing the plough

The plough is usually delivered ready to be used. Due to transport limitations, it may also be at times delivered partially dismantled. Check the technical condition of the plough, especially the moving parts and all bolt connections, before commencing work.

4.2. Selection of the hitching bar

In order to obtain a first ridge of a stable width, the theoretical line of intersection of the lower connectors of the tractor’s suspension system should be at the distance of 1/3 of the tractor’s wheelbase behind the front axle. Failure to do this may cause the plough to “slew”. In such a case, a hitching bar of a different length must be used.

4.3. Hitching the plough to the tractor

The TUZ lower connectors should be at the same height, spaced apart by a distance corresponding to the space between the lower plough suspension points. When hitching the plough to the tractor, the agricultural machinery should stand on a hard and level surface. When hitching the two pieces of machinery together the following must be carried out:

• Suspend the hitching bar on the lower connectors of the TUZ and secure with cotter pins,• Switch the hydraulic system of the tractor to the positioning adjustment,,• Carefully reverse and hitch the agricultural machinery onto the hitching bar and then

secure it with the bolts,• Connect the tractor’s upper connector (when the plough is in operation the fixing

point of the upper connector on the plough should be positioned higher than the fixing point of that connector on the tractor),

• Check the raising, lowering and overall operation of the plough’s hydraulic system.

Connection of upper connector:• Oval (longitudinal) holes allow for better

longitudinal ploughing of the terrain. Use for 4-5 furrow plough, in extreme cases 3-furrow plough.

• A fixed hole prevents the plough from rising up on heavy and stony soils. Use for 2-3 furrow ploughs.

4.4. Adjustment of the hitching bar height

The hitching bar can be set at the height of 64.5 cm and 57 cm from the ground depending on the type of tractor operating the plough. In order to change the position of the hitching bar, first remove the hitching bar from the plough’s suspension system. Then turn the hitching bar handle to the appropriate holes.

4.5. Adjustment of the furrow width

The ORKAN VARIO plough is equipped for an infinitely adjustable furrow width. Changing the furrow width is possible thanks to the use of a hydraulic actuator. The furrow width can be smoothly adjusted, i.e. without steps, anywhere from 30 to 50 cm. The arrow in the photo below shows the position of the furrow width adjustment actuator and its view as seen from above.

18

bolt for adjustment of the width of the �rst ridge

Setting the optimum furrow width is of particular importance for reducing the working resistance of the agricultural machinery and minimizing the degree of soil clumping after ploughing. The operating width of a plough body must be adjusted according to the weather conditions, terrain and the capabilities of the farm tractor. Indicated above is the position of the actuator within the agricultural machinery and the direction of its movement. Extension of the actuator reduces the furrow width, while the maximum position of the actuator corresponds to the maximum furrow width.

4.6. Adjusting the first ridge

The width of the first ridge should correspond to the width of the remaining ridges, but one should also take into account: • resultant compensation of the plough’s operating resistance,• with wide tractor tyres, the width of the first ridge should

be reduced to ensure proper alignment of the front ridges,• For a plough equipped with a furrow widener, the width of

the first ridge should be reduced by 13 cm compared to the width of the remaining ridges.

After altering the working width of the first ridge, one may need to adjust the width of the furrow.

19

transverse levelling adjustment bolt

wheel adjustment crank

4.7. Levelling

The plough is longitudinally levelled by means of the upper connector. The plough frame should always be parallel to the ground. The upper connector bolt should be in the middle of the longitudinal hole.

The plough is transversely adjusted using the bolts with handles. There is separate adjustment for the left and right sides. Looking at the plough from behind, the plough’s beams should be positioned perpendicular to the ground. With any change in the depth of the furrow, a transverse levelling adjustment must be made

4.8. Adjusting the furrow depth.

When attaching the upper connector to the longitudinal holes, it is necessary to set the furrow depth by means of the tractor’s hydraulic (actuator/positional) regulation.

Setting the furrow depth on the gauge wheel is carried out using a screw crank. The setting is the same for left and right-hand side. Bumpers (screws with a counter nut) allow the angle of the gauge wheel arm to be changed relative to the ground. This allows you to change the distribution of forces acting on the gauge wheel moving over difficult terrain. Changing the angle of the gauge wheel arm also results in the change to the depth of the furrow.

4.9. Rolling coulter

Properly set, rolling coulters should work:

• up to half the depth of the furrow made by a plough body,

• at the distance of 1 - 3 cm from the skid,• up to the maximum 1/3 of their diameter,• at the minimum distance of 5 cm before

the edge of the first ridge, the mould-board and the share,

• without interfering with the gauge wheel.

All rolling coulters should be uniformly aligned.

To change the operating depth of the rolling coulter:

• support the cutting arm so that it does not drop down,

• loosen the operating depth adjustment bolt, • turn the frame on the rack to the desired

position, • tighten the bolt. The distance from the skid is set: • by loosening bolts A and B, • turning A bolt on it axis in the longitudinal

hole of B bolt to the desired position, • tightening A and B bolts.

4.11. Skim coulter

The plough share is bolted to a bracket that is mounted on the mouldboard. This bracket has two holes (A) - for shallow and deep ploughing. There are two longitudinal holes in the bracket to be adjusted according to conditions.The front edge of the optimally set plough share should be against the mouldboard, and the rear edge should be adjusted according to the depth of the furrow.

The skim coulter set consists of a bracket bolted to the plough body holder. This bracket supports the skim coulter standard to which the working components are bolted – the plough share and mouldboard. The operating depth of the skim coulter is set using the holes of the bracket by turning the bolts holding the standard. The lower bolt securing the components against overload has a circumferential groove that allows the bolt to be cut. The shear bolt should always be mounted as shown in the drawing above. The distance of the plough share from the chisel is set in two positions: 0 mm and 70 mm. This is set by turning the skim coulters’ bracket 180°.

• The roller protection actuator is connected to the tractor’s external hydraulics. At the end of the field, the operator must free the roller and then raise the plough. Then it should push the pin in using the actuator. During travel, the hook will point itself towards the bolt.

4.13. Assembly and dismantling of the end pair of plough bodies

Ploughs marked with the 3+ and 4+ symbol have the ability to take on an extra beam together with a pair of plough bodies. Before assembling/dismantling, the plough should be secured on a level / hard surface. A means of lifting and transporting the unit should be used. The weight of the complete unit ranges from 210 - 265 kg depending on the equipment bolted to it. Before beginning to bolt on elements, remove the plastic cap. Beams are bolted together with six M20x65 bolts. The complete set includes M20 nuts and Z 20.5 spring washers.

5 Operating the ORKAN VARIO plough

Daily maintenanceAt the end of the each ploughing session, the plough should be cleaned of soil and

plant residue. Check all bolted and pinned connections and the condition of the working components and other parts. In case of damage or wear, such parts need to be replaced. All loose bolt connections should be tightened and any damaged pins and cotters should be replaced. Before operation and after each wash, lubricate the grease points (chapter 5.1). Never direct a stream of liquid at bearings.

Seasonal maintenanceAfter the ploughing season has ended, the plough must be cleaned, any damage

done to the paint coating must be touched up and scratched surfaces thoroughly cleaned and protected. In addition, complete lubrication must be carried out. It is recommended to keep the agricultural machinery under shelter during any longer interval in its operation. However, if this is not possible, check the condition of the protection periodically and, if necessary, make up for any lubricant rinsed off by the rain

5.1. Lubrication

Before lubrication, grease nipples should be thoroughly cleaned. The following grease points should be lubricated depending on the intensity of use:

• plough rotation axles (2 pieces) - 10 hours,

24

• actuator pins (2 pieces) - 10 hours,• connector pin at the head (1 piece) - 10 hours,• connector bolt on the frame beam (1 piece) - 50 hours or once a week,• gauge wheel rotation axle (rotation depending on operation), (1 piece) - 10 hours,• actuator pins for the infinitely adjustable plough width - 10 hours.

Lubricate all lubrication points until bearings or friction surfaces are filled with grease. Remove any grease residue. An excessive amount of grease causes dust and soil particles to cling and clog. Markings indicate the points on the plough requiring regular maintenance, i.e. lubrication.

5.2. Worn out components

All cutting parts (chisel, share, and mouldboard breast) should be used to the maximum until where the cutting piece becomes level with the supporting component (coulter standard shoe). In practice, these components should be replaced early on due to the quality of the work done. The cutting parts (mouldboard, shin, skid) should be used until their thickness is down to 5 mm.

25

shear bolt

5.3. Securing bolts

Chisels can be rotated. Once these are worn down on one side, the bolts are unscrewed and the chisel is turned 180 degrees.

Skids worn down to 5 mm at their ends can be rotated to extend their service life. To this end, turn the skid around 180°. Then the skids on the left-hand plough bodies should be transferred to the right and from the right to the left, according to the drawing.

If the plough body meets an obstacle, the securing bolt is cut off. After lifting the plough to replace the bolt, the body will not return on its own to its original position. It needs to be turned and adjusted accordingly. The tightening torque of the sheared bolts should oscillate between 70 and 79 Nm.

5.4. Gauge wheel

Regularly control the pressure in the gauge wheel. In case of significant air loss, the air valve should be checked for leaks. The next step is to return the gauge wheel to a specialized workshop for locating and repairing the defect. Badly damaged tyres (especially damage to the profile) should be replaced immediately.Setting the axial play of the bearings.This should be checked and adjusted every 2 years. It is recommended that this opera-tion be performed by a specialized workshop. The recommended clearance is 0.12 - 0.15 mm. Procedure:

• Disassemble the hub cover and spring loaded cotter securing the crown nut.

26

gland

control valve

• At the same time as spinning the hub, press and tighten the crown nut,• Cease tightening when a vigorous push of the hand causes no more than half a turn

of the hub.• Partially loosen the nut until the hub is free to rotate and repeat the tightening.• After the repeated locking of the hub, loosen the nut a maximum 30º until the

closest possibility to secure the nut with a cotter pin is found. Mark the position with a line by a felt marker.

• From the marked position unscrew the nut a half turn, and slightly tapping on the hub press the hub onto the nut as far as possible.

• Tighten the nut to the position marked with the line by a felt marker.• Refit the hub cover.

WARNING! During maintenance work the plough should rest firmly on the ground and be protected against tipping over.

5.5. Hydraulic system

Maintenance of the hydraulic system involves visual inspections for its leak tightness. Be sure to put plugs on the quick connectors. If there is any leakage on the hydraulic connections - tighten the connector. If this does not fix the problem, replace the component or line with a new one. Mechanical damage also requires replacement of the subassembly. It is recommended to replace the hydraulic lines every 5 years.If any ingress of oil is found on the hydraulic actuator’s cylinder, the nature of the leak must be checked. When the piston rod is fully extended, check the seals. Minor leaks, recognizable by the appearance of a light film of oil on the piston rod are acceptable (damaged sealing ring). In the event of significant “sweating” or the appearance of droplets, switch off the agricultural machinery until the defect is removed (damaged seal). The hydraulic system controlling rotation is equipped

with a gland that controls the speed of rotation depending on the performance of the tractor’s hydraulic system. During its first start-up, the gland should be twisted to a degree that makes rotation almost impossible. Then gradually unscrew the gland until a satisfactory rotation speed is obtained. The control valve is factory set for proper rotation. Do not tamper with or disassemble this valve. In case of malfunction please contact the service agents.

6 Storing the ORKAN VARIO plough The plough should be stored out of the weather. In the absence of a covered space,

the agricultural machinery may be stored outdoors. The plough should be stored in a location where it is not hazardous to people and the environment. In the event of long-term storage of the agricultural machinery outdoors, maintenance of its working parts should be repeated if its maintenance layer becomes washed off. After its disconnection from the tractor, the agricultural machinery should be support on hard and level ground to maintain a stable balance. All working parts should rest on the ground. The plough should be lowered gently to avoid working parts impacting with the hard ground. After the agricultural machinery has been laid up, its suspension should be disconnected and disengaged from the tractor.

7 Dismantling and disposal The agricultural machinery, if used in accordance with the instructions given in the

manual, will remain serviceable for many years, but any worn or damaged parts must be replaced. In the event of damage (cracks in or deformation of the frame) that compromises the quality of the agricultural machinery and poses a danger if it continues to be operated, the agricultural machinery must be scrapped. Disassembly of the agricultural machinery should be carried out by persons who are familiar with its construction. Such dismantling operations must be performed after the agricultural machinery has been set on a level and hard surface. Dismantle all the metal parts to be scrapped and send any plastic parts to a disposal facility. Oil should be poured into a sealed container and sent to a recycling facility

Warning! Take all necessary precautions when dismantling the agricultural machinery and use proper tools for the job as well as personal protection clothing and equipment. Dismantled parts should be disposed of in accordance with environmental protection requirements.
