Connecting the Lift Arms to the
Cutting Unit
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 2-1/4 in. (57 mm) (Fig. 4). If distance is not
2-1/4 in. (57 mm), loosen the jam nut securing the ball
joint to the lift arm and rotate the ball joint in or out
until the distance is attained. Do not tighten the jam nuts
at this time.

3. Move the lift lever to the Float position. Push the lift
arms down until the holes in the ball joint mounts line
up with the holes in the castor arms.
Note: On the Groundsmaster 3280–D and 3320 the engine
must be running to lower the lift arms.
4. Secure the ball joint mounts to each castor arm with 2
capscrews (7/16 x 3 in.) and flange nuts (7/16 in.)
(Fig. 5).
Note: The ball joint mount should be above the castor arm
when it is assembled.
5. Tighten the large jam nut securing the ball joint to the
lift arm (Fig. 5). When tightening the jam nut, hold the
ball joint straight to permit proper oscillation during
raising and lowering of the cutting unit.
