Maintenance
To Pivot (Tilt) the Cutting Unit Upright:
1. Position the front cutting unit so the rear castor
wheels just clear the floor, set the parking brake and
shut off the engine.
2. Remove the deck tilt link from the tool box under
the traction unit floor (Fig. 53) and klik pins from
the weldments on the traction unit frame and
cutting unit lift arm.
3. Remove the hairpin cotters and clevis pins from the
(2) rear castor assemblies (Fig. 57). Set the left-
hand clevis pin aside and insert the right-hand clevis
pin into the most forward holes in the castor wheel
arm on the right side of the unit (Fig. 58). The
castor arm and pin should be resting on top of the
unit.

position (Fig. 56).

lifting or lowering the unit. Always use proper
lifting techniques and hold unit securely when
pivoting it up or down.
To Pivot the Cutting Unit down into Operating Position:
1. With the help of an assistant, hold the unit upright,
remove the klik pin securing the link end and
remove link end from the weldment.
2. Pivot (tilt) the cutting unit downward.
