Using the Grass Deflectors

The rear grass deflectors must always be correctly fitted. The
deflectors should be set as low as possible to deflect grass
discharge to the ground (Figure
Adjusting the Center
Cutterhead Height-of-Cut
Correction
With all cutterheads set at the same HOC via the indicator
rings, it may be noticeable that the center unit produces a
higher cut finish compared to the wing units. The center
unit is pulled and the wing units are pushed; this presents
marginally different cutting angles relative to the ground. The
amount of HOC variation which results from this will be
influenced by the terrain, but satisfactory results can usually
be achieved by setting the center cutterhead HOC indicator
ring lower than the wing unit settings.
Controlling the Position of the
Individual Cutterheads
The cutterheads may be raised or lowered independently
using the bank of 3 lift control switches.
1. To lower the cutterheads, operate the lift control
switches in a downward direction and release.
The cutterhead drive switch must be on (forward) to do
this, the cylinder drive will engage when the cutterheads
are approximately 150 mm (6 inches) above ground
level. The cutterheads are now in 'float' mode and will
follow the ground contours.
2. To raise the cutterheads, operate the lift control
switches in an upward direction and hold in position 3.
If the cutterhead drive switch is in the On position the
cylinder drive will disengage immediately.
3. Release the lift control switches when the cutterheads
are at the required height.

The control switches will automatically return to
position 2 (neutral) and the arms are hydraulically
locked into position.
Adjusting the Cutterhead Auto
Limited Lift
To activate, press the Auto Limited Lift switch to the On
position (Figure 35).
To deactivate, press the Auto Limited Lift switch to the Off
position (Figure 35).
Manual limited lift using the 3 lift control switches is always
available regardless of the position of the Auto switch.
To raise the cutterheads to the limited lift position:
momentarily operate the switches in an upward direction.
The cylinder drive will disengage immediately and the
cutterheads will stop raising, approximately 150 mm (6
inches) above ground level.
This operates with the cutterheads lowered and rotating.
Auto limited lift in reverse causes the cutterheads to rise
automatically to the limited lift position when reversing. They
will return to the floating position when returning to forward
