WEIGHT TRANSFER ADJUSTMENT_____________________________________
The weight transfer bias can be adjusted on the lift valve. The valve is accessible from under the mower on the
left hand side behind the front axle.
To adjust:
1.
Loosen the locknut A whilst holding the threaded shaft still with the Allen
Key B.
2.
Using an Allen key B rotate the threaded shaft clockwise in direction D
to increase weight onto the drive wheels when the traction control
button is operated on the control pod. This improves slope climbing
performance. To reduce weight on the drive wheels when the traction
control button is operated on the control pod, rotate the threaded shaft
counter clockwise in direction C. It is recommended that the Allen key is
turned a 1/4 turn at a time and the weight transfer tested.
3.
Tighten locknut A. whilst holding the threaded shaft still with the Allen Key B.

WHEEL AND STEERING ALIGNMENT/ADJUSTMENT ______________________
The rear wheels axle stops are set as follows.
1.
Park the machine on a flat and level surface, turn the steering wheel to the centre position, fully lower all
the cutting units/decks to the ground, engage the parking brake, stop the engine and remove the key from
the ignition switch.
2.
Turn the steering wheel so that the steering ram shafts are equal on both sides of the ram
Note: The rear motor mounts "A" and "B" must be
parallel to each other and the machine. The steering ram
shaft must be equal ("C" and "D") on both sides of the
steering ram.
3.
Loosen the four wheel nuts on both rear wheels.
4.
Jack the rear axle up and support it close to both
wheel motors with appropriately rated axle stands.
5.
Remove both rear wheels.
6.
Using two wheel nuts (with flat sides towards plate) fasten an alignment tool plate (Part number
4390586) to each rear wheel hub.
7.
Take the measurement between the fronts of the
left hand and right hand alignment tool plates and
compare this with the measurement between the
rears of the alignment tool plates.
8.
The measurements should be equal, i.e. there is a
0mm to 3mm (1/8") of toe-in.
9.
If the measurements are not equal, hold steering
link "F" and undo locknut "E".
