Position the machine and cutting unit on a level surface and
lower the cutting unit. Remove the dipstick/fill plug from
the top of the gear box (Fig. 17) and make sure that the
lubricant is between the marks on the dipstick. If the
lubricant level is low, add SAE 80–90 wt. gear lube until
the level is between the marks.

Separating the Cutting Unit
from the Traction Unit

1. Position the machine on level surface, lower the cutting

unit to the floor, shut the engine off, and engage the
parking brake.

2. Remove the self-tapping screws securing the shield to

the top of the cutting unit and set the shield aside.

3. Drive out the roll pin securing the drive shaft yoke to

the input shaft of the gear box (Fig. 18). Loosen the
capscrews and locknuts and slide the yoke off of the
input shaft. If the traction unit will be used without the
cutting unit, drive the roll pin out of the yoke at traction
unit PTO shaft and remove the entire drive shaft from
the traction unit.
