9.1 TRACTION CONTROL PEDAL ________________________________________
The LPV transmission pump has an internal neutralising
mechanism which cannot be adjusted. If the machine does
however creep carry out the following.
1. Lift and support both front and rear wheels.
2. Remove ball joint from pump lever to allow pump to
neutralise.
3. Start engine, manually move the pump control lever
and release to ensure wheels stop rotating.
4. Operate foot pedal to ensure cable is free.
5. Reattach ball joint to pump lever.
6. Move the foot pedal in forward & reverse directions to ensure there is no creep in neutral position.
9.2 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. The centre unit will have to
be swung out of the way.
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. 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.
3. Tighten locknut A. whilst holding the threaded shaft still with the Allen Key B.
