Connecting the Lift Arms to
the Cutting Unit
No Parts Required
Procedure
1. Move the cutting unit into position in front of the
traction unit.
2. Measure the distance from the end of each lift
arm to the center of the ball joint (grease fitting).
The distance should be 57 mm (2-1/4 inches)
(
Figure 6 ).
Note:
If the distance is not 57 mm (2-1/4
inches), loosen the jam nut that secures the ball
joint to the lift arm and rotate the ball joint in or
out until you attain the distance. Do not tighten
the jam nuts at this time.
