2. USAGE INSTRUCTIONS
2.1 BEFORE USE & ADJUSTMENTS
1. Before mounting of disc harrow make sure that all nuts & bolts are properly
secured.
2. Also determine soil and trash conditions of the field and make the preliminary
adjustments. e.g.
a) Disc gang angle adjustment :-
Gang angle (Angle between two gangs) ranges between 40
0
to50
0
. The
angle can be increased for better penetration in dry soil while it should be
reduced to avoid plugging in wet soil.
b) Disc harrow leveling: - To eliminate uneven penetration and side draft, leveling
is done by means of top link. While tractor pulls to right the rear gang should be
lowered a little. When the tractor pulls to the left the rear gang should be raised.
c) Scrapper adjustment:-
The scrapper can be adjusted by loosening the bolts at the scrappers clamp.
d) Depth control:-
The depth at which the implement is required to work is controlled
hydraulically by raising or lowering the control lever on the tractor.
e) Disc harrow penetration :-
Factors affecting disc harrow penetration are:-
Angle of the gang
Weight of the harrow
Disc diameter
Disc sharpness
(Blunt disc increases the draft considerably, check the disc sharpness)
Angle of hitch
2.2 ATTACHING THE HARROW TO THE TRACTOR
1. Place the harrow duly leveled on the flat piece of land.
2. Reverse the tractor to the harrow ( Do not drag the harrow up the tractor)
3. Attach the left arm of the tractor to the harrow first.
4. Attach the central arm to the harrow. To attach, turn the screws on both sides to
an equal length. If the arm is too short or too long, turn the screw to adjust both
at the same time until aligned with the hole on the central arm.
8
5. Attach the lower right arm, turn the screw until the mounting pin is at the same
level as the hole on the tractor arm. If the gap between the hole and mounting
pin is too close or too distant, turn the control arm in or pull it away to an
appropriate distance. You may have to adjust both height and distance at the
same time. When the hole at tractor arm and mounting pin are even, insert the
pin in the hole and lock it with the lynch pin.
6. After attaching the harrow, lift it and adjust the control arm parallel to the
ground. When you look from both rear or sideways, the discs should all be
touching the ground uniformly.
2.3 WARNING FOR THE DRIVER
Before harrowing check all nuts & bolts of the disc harrow.
Be vigilant about the tree roots and stones. Don’t harrow on stony soil.
Tractor should be in first high or fourth low gear.
Don’t allow anyone to come across the harrow.
Lift the disc harrow on every turn.
Lift the harrow before approaching the road.
1.4 SAFETY
Understanding the Machine Safety Labels

1. If the soil has entered the grease nipple, then change the nipple.
2. If disc harrow is new after initial working of first two hours, tighten all nuts &
bolts.
3. After every fifty hours grease all greasing points with grease gun and tighten all
nuts & bolts.
4. After fifty hours, open the bracket spool of Disc harrow & cleanse with diesel oil
& pump in new grease.
3.2 STORAGE OF MACHINE AFTER WORK
1. Wash the Disc harrow after work.
2. Replace the worn out nuts & bolts.
3. If disc harrow has to remain unused for long time then clean it & apply a layer of
used oil for rust prevention.
These steps will enhance the life of your Disc harrow.
In order to protect yourself always wear adequate
clothes and shoes during the operations.
Never allow riders on the tractor or implement unless
on additional seat is available.
Be careful whe
n moving around steep graders to avoid
over turn.
Never transport the implement on rough roads during
the night. When operating, avoid to make sharp turns
that may contact with the implement

3.3 LUBRICATION
Please take care that high quality grease is used in spools.
3.4 INSTRUCTIONS FOR DRIVER
1. When Disc harrow is ready for use don’t stand between disc harrow & the
Tractor.
2. Properly fit the three point linkage as mentioned above & lock with lynch pin.
3. In case of scrapper touching the discs, loosen the scrapper bolt and readjusts the
scrapper.
4. Never turn the tractor to the right or left when the harrow is engaged in the soil.
5. Never reverse the tractor when the harrow is engaged in the soil.
6. To get good results from the harrow, disc should be replaced when its diameter
is reduced by 5”from its original size.
4. OPERATIONAL GUIDELINES FOR HARROW
1. Lift the harrow on turning for effective independent breaking of soil.
2. Adjust internal /external check chains to obtain implement swing range with in 50
mm (2”) when raised.
3. Always maintain the correct tyre pressure to avoid wheel slippage.
4. Adding of wheel weights/water ballasting or combination of both is recommended
when excessive rear wheel slippage is experienced.
5. Always set hydraulic levers correctly for draft and position control operation.
The following settings are necessary to ensure that uniform working depth is
maintained:-
a.) Side draft:-
The offset disc harrow will trail correctly behind the tractor provided the side thrust of
the front gang is equal to that of rear. In case it is different there will be side draft. To set
it correctly, the gang angle should be changed.
b.) Severe Side Draft:-
In case of severe side draft the cutting depth of rear disc gang should be increased or
decreased with the help of tractor top link. For instance when tractor pulls to right, lower
the rear gang and when tractor pulls to left, raise the rear gang.
Precautions during transportation:-
1. When transporting the harrow, shorten up top link to minimum length.
2. Set hydraulic levers in top raised position and lock levers.
3. Maintain the speed to avoid jumps.
4. Watch while overtaking on road.
5. Always use SMV (Slow Moving Vehicles) symbols.
