all lift levers are in the float position and stop the
engine.
4.
Connect the wire harness and (3) hydraulic lines
couplers at the rear of the deck.
Separating the Cutting Unit From
the Traction Unit
1.
Lower the center and wing cutting units to the
ground; then raise the center cutting unit slightly,
until the rear deck straps hang freely on the lift arm
brackets. Stop the engine after the cutting unit is
raised. Set the parking brake.
2.
Remove the hairpin cotters and height-of-cut pins
securing the rear deck straps to the height-of-cut
brackets on the deck. Start the engine and lower
the center cutting unit completely to the floor. Stop
the engine after the cutting unit is lowered.
3.
Disconnect the (3) hydraulic lines (quick couplers)
and the wire harness at the rear of the deck.
4.
Remove the socket head screws securing the drive
shaft yoke to the gear box input shaft. Slide the
yoke off the shaft.
5.
Remove the (4) capscrews, flatwashers and flange
nuts securing the ball joint mounts to the castor
arms on the cutting unit.

Alternate Method
1.
Lower the center and wing cutting units to the
ground, set the parking brake and stop the engine.
2.
Disconnect (3) hydraulic lines (quick couplers) and
wire harness at the rear of the deck.
3.
Remove the socket head screws securing the drive
shaft yoke to the gear box input shaft. Slide the
yoke off the shaft.
4.
Remove (2) capscrews and locknuts securing the
cutting unit carrier frames to the traction unit lift
arms (Fig. 68).

5.
Slowly back the traction unit away from the cutting
unit.
Mounting the Cutting Unit to the
Traction Unit
1.
With the cutting unit on a level surface, move the
traction unit into position, aligning the drive shaft
yoke with the gear box input shaft and lift the arm
ball joints with the mounting holes in the castor
arms. Shut the engine off.
2.
Secure the ball joint mounts to the castor arms with
capscrews, flatwashers and flange nuts. Tighten the
capscrews and flange nuts to 136–149 Nm (100-
110 ft-lb.).
3.
Line up the holes in the yoke and the input shaft of
the gear box. Slide the yoke onto the shaft and
secure them together with socket head screws.
