Using
Weight-Transfer/Traction
Assistance
A variable hydraulic weight transfer system is provided
for improving tire grip with the grass surface—traction
assistance.
Hydraulic pressure in the cutting units lift system
provides a lifting force which reduces the weight of the
cutting units on the ground and transfers the weight
as a downward force onto the tires of the machine.
This action is known as weight transfer.
To engage weight transfer: The amount of weight
transfer can be varied to suit operating conditions by
rotating the weight-transfer hand wheel
as follows:
1. Release the valve locknut 1/2 turn
counterclockwise and hold
2. Rotate the valve hand wheel

counterclockwise to reduce weight transfer or
clockwise to increase weight transfer.
3. Tighten the nut.
Note:
The recommended setting is to increase
weight transfer until heads start to lift, then back off
1/2 turn, and lock.
