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 (
)
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.

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.
2.
Support the weight of the upper frame while
removing the R-clips and pins from the pivot
brackets (
).
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.
