Figure 39
1. On 2. Off
The cutting unit drive can be engaged only when the
operator is seated correctly, refer to
Checking the
Operator-Presence-Seat Switch (page 47) .
Cutting unit drive engagement: Press the top of the
cutting-unit-drive switch to the on position ( Figure 39 ).
All cutting unit drives disengagement: Set the switch to
the off position ( Figure 39 ).
To lower the cutting units: The cutting unit drive switch
must be set to the on position. Operate the lift-control
switch(s) in a downward direction. The machine drives when
the cutting units are approximately 150 mm (6 inches) above
ground level.
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 (
Figure 40 ) as follows:
1. Release the valve locknut 1/2 turn counterclockwise
and hold (
Figure 40 ).
2. Rotate the valve hand wheel ( Figure 40 )
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.

Folding the ROPS
You can fold the ROPS frame down to allow access into areas
of restricted height.
WARNING
The machine does not have a Rollover Protection
System when the ROPS is folded down and should
not be considered as Rollover Protection System.
Do not wear a seatbelt when the ROPS is lowered.
1. Park the machine on a level surface, engage the parking
brake, and shut off the engine.
2. Support the weight of the upper frame while removing
the R-clips and pins from the pivot brackets (
Figure 41 ).
3. Carefully lower the frame downwards until it rests on
the stops.
4. Insert the pins in the lower holes and secure with
the R-clips to support the upper frame in its lowered
position.
5. To raise the frame, follow these instructions in reverse
order.
