PRECAUTIONS
 Keep all safety shields in place and in good repair. Rotating shafts cause
severe injury in a matter of seconds by entangling loose or dangling
clothing. Keep a safe distance from all cutting or moving parts. Do not allow
anyone to lean, push or stand on diggers to aid in penetration.
 When repairing or working on an implement, make sure it is lowered to the
ground. It should be blocked securely if you have to work on it in the raised
position, don’t depend on hydraulic cylinders to support the implement
alone.
 Always turn off power source and wait for all moving parts to stop before
working on the implement.
 Make sure the operator knows how to operate the machine
 Cutting equipment should handle properly.
 Integral ploughs are transported completely raised and all weight is carried
by the tractor 3 point hitch. Adequate tractor front-end weights are required
to offset the plough weight.
 When the transporting on a road or highway, always display SMV emblem
and use lights and reflectors as required by state and local regulations.
 Semi-integral plough are quite long and caution must be used when turning
to prevent swinging the plough in to fences or irrigation ditches.
 Reduce speed when transporting over rough ground and avoid quick, sharp
turns at high speeds.
 When transporting semi-integral or drawn plough, always Install cylinder
locks to prevent accidental lowering of the plough. Relieve the load on
hydraulic cylinders before starting to transport.
 Lower the plough to the ground or install hydraulic cylinder locks when the
plough is not in use.
 Watch for other people when raising, lowering or indexing the plough.
 Never permit anyone to ride on the plough and allow only the driver on the
tractor. Do not permit children to play on or near the plough either when
parked or in operation.
 Lower the parking stand and securely pin it in place before detaching
integral or semi-integral plough on the tractor.

PREPARATION ON TRACTOR
2.1 Fuel and Lubrication
Fuel oil should be checked in the fuel tank. If it is not adequate, fuel oil
should be added to the tank.
Transmission oil should and Lubricating oil should be checked by a dipstick
and if necessary it should be topped up.
Greasing point should be checked, to see whether they have been greased or
not.
2.2 Cooling System and Air Cleaner
Water in the radiator should be checked, if necessary it should be topped up.
Air cleaner should be checked to see whether it is clean or blocked. If
blocked, it should be cleaned.
2.3 Tyres
The air pressure must be identical, particularly on the rear tyres under
difficult conditions, addition wheel weight should be used or the tyres topped up
evenly with water. See operating instruction of the tractor manufacturer
2.4 Fan Belt and Important Nut Bolts
Fan belts and Important Nuts and bolts should be adjusted, if any of them is
too tight or loosened
2.5 Lifting Roads
The lifting rods should be adjusted so they are as short as possible and if
equal length. See operating instruction of the tractor manufacturer

MAHINDRA A PP L I TR AC
2.6 Top Link
Where there are alternative fitting positions at the tractor for the top link, fit
the top link tractor-sided as high as possible.
2.7 Chain and stabilizer of the three-way linkage
The chain or stabilizers must be adjusted so that they ensure adequate lateral
moments at the lower link of the tractors during work
 They must be laterally locked if the lower links are raised and are in the
transport position.
 Some makes of tractor equipped with automatic side structs, it must be
specially adjusted.
If the tractor suddenly pulls to one side implement works with different
widths on the right and left, this may cause by the side struts not having
been released. The function of the locking device of the automatic side
should be checked and readjusted if necessary. See the operating manual
provided by the tractor manufacturer.
2.8 Hydraulic
For work the tractor hydraulic must be set to draft or mixed control. See
manufacturer instruction.
2.9 Hydraulic Equipment Required
The implement is supplied at standard with separate hydraulic coupling for
each consumer. The protecting caps on the hydraulic couplings are colored and the
hydraulic couplings themselves are marked alphanumerically.
In order to operate the hydraulic devices, the tractor must be equipped with a
double acting spool valve.

Operating MB Plough
 Field Operation
 Before field operation:
 Apply grease at all the greasing points
 Make sure nut bolts for discs; scraper and coulter wheels are properly
tightened.
 Lift MB Plough and remove the stand and fix the stand at upper position.
 Operating Instructions:
 Attach the MB Plough as per instructions given. See section “Attaching and
detaching MB Plough”
 Maintain the forward speed of 3 to 5 kmph and rated ERPM to get the
optimum output.
 Lift the plow while turning the tractor and engage again once the turn is
completed.
 Do not make sharp turns or attempt to back up while MB Plough is in the
ground.
 Periodically check the weeds or soil or trash is blocked in between the
scrapers and remove them after stopping the tractor and removing ignition
key.
 Before starting plowing, select one of the tillage patterns and follow the
same to get the field leveled.
 Operating the hydraulic controls
 I. Position Control (PC) Lever: Position control lever (A) controls the lifting
and lowering of implement.
 Make sure that all the discs of the plow are touching the ground and
parallel to ground surface. This will help in getting uniform depth of
plowing.
 Adjust the hydraulic depth control lever to get the desired depth of plowing.
 Make sure the current position of the coulter so get plowing in straight line.
 This lever should be used for transport of implement, turn around at the end
of the field and constant depth of operation. Before setting PC lever to get
constant depth, move the Draft Control (DC) lever to its most forward
position. Place the PC lever at desired depth.
 II. Draft Control (DC) Lever: This lever is moved forward to deepen the
implement and rearward to shallow it. This lever is used for keeping the

MAHINDRA A PP L I TR AC
draft on the implement constant and is useful while using it on leveled field
with constant soil texture. Please refer tractor Operator manual for using the
position and draft control levers.
 Do not transport or attach equipment when the hydraulic system is in Draft
control. Always lower the implement to ground level before stopping the
tractor. Do not use Draft control lever to lift implement to its uppermost
position.
Adjustments for MB Plough
Adjusting the Width of Cut
This adjustment should be used for
increasing or decreasing the width of
cut. If the tractor is working under
high load condition, decrease the
width of cut.
1. Loosen the bolt (A) and four bolts
of Bolt (2 on either side B).
2. Rotate the hinge bar (C), so that
the bolt A should fix to the next
screw seat on the shaft.
3. For decreasing the width of cut
(by 25 cm) the plow rotate the
hinge bar / shaft (C) in clock wise
direction as shown above.
4. For increasing the width of cut
(by 25 cm) the plow rotate the
hinge bar / shaft (C) in counter
clock wise direction.

Adjustments for deeper ploughing:
The depth of the plough can be obtained by the position and draft control
levers of the tractor hydraulic system. However more depth can be obtained by:
a. Adding extra weight to the plough.
b. Reducing the tilt angle. A correctly tilted plough tends to penetrate
better.
c. If the ground is covered with trash, set the Plough in almost vertical
position and add weight to the plough. In such soils notched Plough gives
better results.

increases. Please follow these rules to get the best results:
1. If M.B. plough is new then after first two hours of working tightened all nut
bolts.
2. Check the plough adjustments if the steering is hard.
3. After every fifty hours tighten all nuts and bolts.
4. Constantly check for loose nuts and bolts.
5. Sharpen the Bar Point and Blades if the blades are dull. Blunt blades increase
the draft considerably.
