Adjusting the Cutting Unit
Auto-Limited Lift
Note:
You enable the cutting-unit Auto Limited Lift
feature in the settings menu of the InfoCenter.
•
Manual limited lift uses the 3 lift-control switches,
and is always available regardless of auto-limited
lift setting in the InfoCenter.
•
When cutting-unit Auto Limited Lift is enabled,
driving the machine in reverse causes the cutting
units to automatically raise to the limited-lift
position.
•
The cutting units return to the floating position
when driving the machine forward.
To raise the cutting units to the limited-lift position,
momentarily pull the lift-control switches.
Note:
The cutting-unit drives disengage immediately,
and the cutting units raise to approximately 150 mm
(6 inches) above ground level.
Auto-limited lift operates with the cutting units lowered
and rotating.
Cutting Unit Drive
The cutting unit drive engages only when you sit in
the operator’s seat; refer to

Adjusting the Weight
Transfer/Traction
Assistance
A variable hydraulic weight transfer system provides
improved tire grip with the grass surface—traction
assistance.
Hydraulic pressure from the cutting-unit lift system
provides a lifting force that reduces the weight of the
cutting units on the ground and transfers the weight
downward to the tires. This action is known as weight
transfer.
Note:
Adjust the amount of weight transfer to suit
operating conditions.
