When operating in Draft Control, draft signals are
transmitted via the top link and hydraulic lift rocker to the
control valve within the hydraulic system. The draft
signal transmitted may be varied by adjustment of the lift
rocker connections.
The lift rocker has three holes for attachment of the top
link as shown in figure 8.2
SWINGING DRAWBAR
The E-marked Swinging Drawbar which is retained by a
single pivot pin at the front, may be allowed to swing the
full width of the hanger or be retained in a fixed position
by the insertion of pins through holes in the hanger.
The Swinging Drawbar is fully adjustable for projection
relative to the P.T.O. output shaft.
To vary the height of the drawbar / implement hitch point,
invert the drawbar and/or reposition the clevis straps
shown in Figure 8.4.

The right-hand lift rod is adjusted by means of a crank
handle on the leveling box. See Figures 8.1
The leveling box as shown in Figure 8.1 is fitted on
tractors in territories where ROPS is also installed.
Turn the crank handle clockwise to shorten the lift rod or
turn anti-clockwise to lengthen the lift rod.
8.2 Hydraulic Lift Rocker
The locking handle should be turned away from the top
link to unlock the top link before adjusting it. The sleeve
can be adjusted by rotating it in clockwise or
anticlockwise direction with the help of the locking
handle itself. Always ensure that the top link is locked
after the adjustments are carried out.
Rocker Hole Selection
The top link length is adjusted by turning the sleeve by
means of a locking handle. See Figure 8.2. Most
equipment will operate at the correct depth/height if the
top link is set to a nominal 27 in. (685 mm) measured
between the centers of the attaching pins.
IMPORTANT : When attaching mounted or semi-
mounted equipment to the three-point linkage or when
oupling trailed equipment to the drawbar, ensure that
there is adequate clearance between the implement
and the tractor. The clearance in the raised position
should be checked by raising the implement carefully in
Position Control. Check the swing clearance by
performing a series of left and right-hand turns with the
tractor and implement combination. Ensure that the
stay bar are adjusted to prevent damage to the tractor.
In some territories, top link with lockable handle is also
provided. See figure 8.2.
