The cutting unit drive can be engaged only when the operator
is seated correctly, refer to
Seat Switch (page
44).
Forward rotation cutting unit drive engagement: Press
the top of the cutting unit drive switch to the forward position
(Figure
32).
Reverse rotation cutting unit drive engagement: Press
the bottom of the cutting unit drive switch to the reverse
position
(Figure
32).
All cutting unit drives disengagement: Set the switch to
the middle position
(Figure
To lower the cutting units: The cutting unit drive switch
must be set to forward. Operate the lift control switch(s) in a
downward direction. The reel drives when the cutting units
are approximately 150 mm (6 inches) above ground level.
Clearing the Cutting Units
WARNING
Never attempt to rotate the cutting units by hand.
There may be some residual pressure in the
hydraulic system, which could cause injury through
sudden movement of the cutting unit(s) when the
blockage is released.
• Always wear protective gloves and use a suitable
strong wooden instrument.
• Ensure that the wooden instrument will fit
between the blades and through the reel and is
long enough to provide sufficient leverage to
release the blockage.
1. Park the machine on a level surface, lower the cutting
units to the ground or securely lock them in the
designated transport positions, engage the parking
brake, shut off the engine, and remove the key from
the ignition switch.
2. Release all stored energy devices.
3. Check that all moving parts are stationary.
4. Using a suitable strong wooden instrument, remove
the blockage. Ensure that the wooden instrument is
properly supported in the cutting unit and avoid the
use of excessive force to prevent damage.
5. Ensure that the wooden instrument is removed from
the cutting unit before restarting the power source.
6. Repair or adjust the cutting unit if required.

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 unit 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
1. Release the valve locknut 1/2 turn counterclockwise
and hold
(Figure
2. Rotate the valve hand wheel
counterclockwise to reduce weight transfer or
clockwise to increase weight transfer.
3. Tighten the nut.

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 (ROPS) when the roll bar is folded down
and should not be considered a ROPS.
Do not wear a seatbelt when the roll bar is lowered.
1. Park the machine on a level surface, shut off the engine,
engage the parking brake, and remove the key from
the ignition switch.
