Setting Up Your Machine
Height
To alter the height of cut; raise the machine so the wheels are clear of the ground,
remove pin
a
(Fig. 3) adjust the wheel arm, replace pin
a
(Fig 3) and gently lower the
machine until the wheel contacts the ground. Fine adjustment can be made by
moving the spacers on the wheel fork above or below the wheel arm, spacer
b
(Fig
3). Now adjust the height of the tractor link arms so the front of the mower is 25mm
(1”) higher at the front
c
.
The top link must be adjusted to ensure the wire ropes are slack, so the machine can
follow undulating ground fore and aft, but still allow the machine to lift when the
tractor link arms are fully raised.
Wings
Unfolding the wings if the machine is in the transport position, first pressurise
hydraulic rams before releasing locking bar (Fig 4), lower both wings by releasing
hydraulic pressure, leaving tractor spool in float position (Fig, 5).
Levelling the wing cutting height LH & RH
With the wings lowered, adjustable skids alter cutting height, these should be set to
maintain minimum cutting height 12mm (1/2”) above the centre blades. When fitted
with optional wheels to the wings, the skids should be raised above the ground and
the cutting height controlled by the height of these wheels.
Note
To achieve a level cut with the wing wheels, they need to set lower than the centre
wheels.
