Cutting Unit Removal and Installation
IMPORTANT: When sharpening, setting height-of-
cut, or performing other maintenance procedures
on the cutting units, store the cutting unit reel mo-
tors in support tubes on the frame to prevent dam-
age to the hoses. Do not raise suspension to
transport position when the reel motors are in the
holders in the traction unit frame. Damage to the
motors or hoses could result.
Removal
1. Park machine on a clean and level surface, lower
cutting units completely to the ground, stop engine, en-
gage parking brake, and remove key from the ignition
switch.
2. Remove basket from carrier frame.
3. Loosen flange head screws that secure the hydrau-
lic motor to the bearing housing. Rotate motor clock-
wise, and remove motor (Fig. 36).
4. Place protective plastic cap (see Special Tools) into
the hole in the bearing housing from which the hydraulic
motor was removed.
5. Slide sleeve back on each ball joint receiver. Re-
move receiver from each unit’s ball studs (Fig. 37).
6. For the front cutting units, slide cutting unit lift roller
off the lift arm while siding the cutting unit from the pull
frame (Fig. 37).
IMPORTANT: Do not operate the lift system when
the rear cutting unit is in the service position. Dam-
age could result to the pull frame and clevis assem-
bly.

A. Slide cutting unit lift roller off the lift arm.
B. Lift carrier frame by hand until the anti-scalp roll-
ers clear the brake linkage.
