SEPARATING THE CUTTING UNIT FROM
TRACTION UNIT
1.
Position the machine on a level surface, lower the cutting unit
to the shop 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 the roll pin out of the yoke and input shaft of the gear
box (Fig. 9). Also, loosen the capscrews and locknuts. Slide the
yoke off the input shaft. If the traction unit will be used with-
out the cutting unit, drive the roll pin out of the yoke at the
PTO pivot shaft and remove the entire universal shaft from the
traction unit.
Do not start the engine and engage the PTO lever when the
PTO shaft is not connected to the gear box on the cutting
unit. If the engine is started and the PTO shaft is allowed to
rotate, serious injury could result.
4.
Disconnect the spring from the lift cylinder cotter pin. Remove
the cotter pins and clevis pins securing the lift chains to the lift
arm.
Since the right hand push arm is springloaded to about 100
pounds (445 N ) and left hand push arm is spring-loaded to
about 150 pounds (667 N), a helper is needed to release
push arms from the cutting unit. Sudden release of the push
arms could cause injury.
5.
Have a helper push down on the right push arm while you
remove the capscrews, flatwashers, lockwashers and nuts
securing ball joint mount to the caster arm on the cutting unit
(Fig. 9). Now the helper can carefully allow push arm to move
upward, which will gradually release the spring load.
6.
Have a helper push down on the left push arm while you
remove the capscrews, flatwashers, lockwashers and nuts
securing ball joint mount to mount bracket on the cutting unit
(Fig. 10). Now the helper can carefully allow push arm to
move upward which will gradually release the spring load.
