Cutting Unit Installation
Cutting unit models 03854 and 03856 can be installed
at any of the five mounting locations on the traction unit.
Figure 17 shows the orientation of the hydraulic drive
motor for each of the five locations. For any of the loca-
tions requiring the motor to be mounted on the right end
of the cutting unit, install a counter weight on the left end
of the cutting unit. For the locations requiring the motor
to be mounted on the left end, install a counter weight on
the right end of the cutting unit.
NOTE: Counterweights with speed sensors must be on
cutting units to be mounted in the front center and left
rear positions on the tractor.

1. Lubricate and install a large O–ring into bearing hous-
ing groove on each end of cutting unit (Fig. 28 & 30).
Note: Before installing cutting unit motors or counter-
weights with speed sensors, lubricate internal splines of
cutting unit reels shafts with grease.
2. Install a counter weight onto appropriate end of each
cutting unit with capscrews provided (Fig. 28 ).
3. Install shims as required on pivot shaft of each cutting
unit carrier frame (Fig. 29). Use enough shims (0 to 2)
to remove any vertical play, but still allow free rotation
when lynch pin (5) is installed.
4. Insert the pivot shaft of the carrier frame into the
mounting hole at the end of the pivot knuckle (Fig. 29).
5. Guide the pivot knuckle in place between the two rub-
ber centering stops on the carrier frame (Fig. 29).
6. Insert the lynch pin into the cross hole on the pivot
shaft (Fig. 29). (If pin does not fit, remove one of the
shims from the pivot shaft.)
