If the cutting unit drive shaft tube and shaft were separated, ensure
that the slip shaft yoke and slip tube yoke are aligned when the tube
and shaft are assembled. Misalignment of the yokes will result in
shortened drive shaft life and will cause unnecessary vibration when
the cutting unit (or implement) is operated.
1. Apply antiseize lubricant to the splines of the center gear box shaft (4),
cutting unit drive shafts (3) and cutting unit gear box (1).
Support the drive shaft (weighs approximately 16 Kg (36 lb)) to
prevent it from dropping and causing personal injury when installing.
2. Position the cutting unit drive shaft (3) to the main gear box (4). Ensure that
the slip tube yoke is toward the cutting unit gear box.
A. Align the splines on the main gear shaft (4) to the cutting unit drive shaft
and press the quick release pin (2) and slide the cutting unit drive shaft
onto the main gear shaft.
B. Release the quick release pin (2) and check the locking of drive shaft (3)
by slightly pulling backward.
3. Position the cutting unit drive shaft (3) to the cutting unit gear box shaft (1).
