ASSEMBLY INSTRUCTIONS
Mower assembly must be completed by a qualified technician using safe
work practices and proper tools.
REAR MOWER DECK
The center rear mower deck, lift arm and drive belt are placed on a temporary rack for shipping
purposes. The RH wing deck can be used as an assembly reference.
1. Remove the deck and the lift arm assembly from the rack. A chain hoist or lift truck and straps
will be necessary (deck assembly weight
– approx. 250lb).
2. Remove both of the center shields of the main drivetrain by extracting (8)
3/8” bolts in order to
install deck drive belt on to the gearbox.
3. Remove (2)
5/8” bolts and bushings that are installed in the lift arm yoke mounts.
4. Roll the deck assembly into position at the center-rear of the mower and remove the rear deck
shields by extracting (2)
3/8” X 3 3/4” bolts.
5. The rear deck belt is then installed by starting at the drive pulley (rear of gearbox), down behind
the frame and twisting it 1/4 turn to ride on the idlers (both fixed and moveable) and then onto
the deck spindle pulley
6. Position the lift arm so that the 5/
8” bolt and bushings can be attached to the frame. Some
alignment of the deck will be necessary to thread both bolts into the frame.
7. Attach hydraulic hoses to a hydraulic power source. Stroke the center cylinder out completely.
Remove the cylinder pin by loosening the 3/8” bolt that holds it in place. Relieve any residual
hydraulic pressure and disconnect from power source.
8. The rod end bushing is placed between the slotted plates on the lift arm. Push the pin through
one slot, through the bushing and through the other slot. Tighten the bolt being sure the bolt
end rests in the indent in the pin at its center. .The pin is now locked in place.
9. The shock absorber is then installed in the threaded hole located on the side of the lift arm near
where the end of the shock rests. Use the fasteners shipped on the loose end of the shock.
10. Re-install the shields on the main drive train and the center deck.
11. There are two rectangular plastic plugs taped to the frame of the mower. They serve to fill the
tube ends on the frame where the temporary transport frame was installed.
