WEIGHT TRANSFER ADJUSTMENT

The weight transfer bias can be adjusted on the lift
valve. The valve is accessible from the front of the
machine and is situated under the right hand side of
the footplate when facing the machine (left hand side
when viewed from the operating position).
To adjust:
Loosen the locknut A whilst holding the
1.
threaded shaft still with the Allen Key B.
Using an Allen key B rotate the threaded
2.
shaft clockwise in direction D to increase
weight onto the drive wheels when the
traction control switch is operated on the
control panel. This improves slope climbing
performance. To reduce weight on the
drive wheels when the traction control
switch is operated on the control panel,
rotate the threaded shaft counter clockwise
in direction C. This increases the ground
weight of the cutting unit and will reduce the
possibility of cutting unit "bounce" when
working at high speed on undulating
ground. It is recommended that the Allen
key is turned a 1/4 turn at a time and the
weight transfer tested.
Tighten locknut A. whilst holding the
3.
threaded shaft still with the Allen Key B.
