3 POINT LINKAGE SYSTEM
The tractor is equipped with a 3 Point (3P) Linkage
System, Category 2 (CAT-II). To make sure that the
tractor runs smoothly, check if the equipment is
suitable for three point linkage and hydraulic lift.
3P linkage system consists of the parts shown in
"Figure 17".
1. Center Arm:
Links the top of the equipment frame to the top
point and conveys the sensitivity data from the
equipment to the hydraulic valve.
i. The center arm has two stabilizing holes
for tractor linkage.
ii. The center arm pipe is movable and can
be turned clockwise and counterclockwise
to adjust the equipment angle according
to the ground; it is fixed with the lock nut
at the end of the pipe.
2. Linkage Arms:
There are two linkage arms with one on each side
and they link the lifting arms to drawbars. They are
used to adjust the position of the equipment
according to the ground. Turn them clockwise or
counterclockwise to adjust their position according
to the level of drawbars. Once the adjustment is
completed, you can fix them with the lock nut at
the end of the pipe.
3. Stabilizer Chains
These chains can be adjusted to limit the side-to-
side movement of lower drawbars of the three
point linkage system.
For plough and similar equipment, adjust the
length of the chains to give a 5 to 6 cm free play.
While carrying equipment in 3 point linkage
system, restrict the lateral movements completely.
To increase or decrease the lateral movements
turn it clockwise or counterclockwise, when you
make the desired adjustments tighten the lock nut.
4. Drawbars
It is used for linkage to the lower points of
implement frame and it is fixed. The arms that
draw the equipment are these two drawbars.
The drawbars have a play that allows the lateral
movement of it and to balance this, it is supplied
with a spring on it, part (5) shown in “Figure 17”.
With the implement disengaged this spring should
be installed, thereby, it prevents drawbars to hit
the tires particularly when the tractor is adjusted
to small track width.
While driving on the road ensure that the stabilizer
chain slack is took up and the springs have been
placed on the arms if the implement is not
engaged.
After mounting and dismounting the equipment,
be sure that you safely hitch the equipment by
using safety pins.
Pay special attention while mounting an
implement to the tractor.
