2.5 Folding and Unfolding
2.5.1 Unfolding into the Work
Position
1. Ensure that the taps on the rear axle
cylinder (Fig. 2.01, taps A and B) are in
the open position (ie. in line with flow).
2. Remove the transport strap from the
rear wing cylinders. Do not climb on
the machine to remove the transport
strap.
3. Lift the machine clear of the ground
ready for unfolding.
4. Operate the hydraulics to fully unfold
the wings.
When wings are fully lowered
they will appear to be lower at
the wingtips. This is to enable
the machine to ‘float’ over uneven
ground in work and is normal.
5. Ensure that the parking stands are in
the fully raised position.
6. Lower the machine to the ground until
the drawbar cylinders touch the depth
stops.
7. Retract the rear axle cylinders
completely.
8. Close the taps on the rear axle to lock
the wheels clear of the ground during
work.
9. Check the wing pressure on the
gauge (shown in Fig. 2.02). If this is
above or below the desired value then
pressurise the wings to fold which will
zero the setting. Increase the pressure
on the cylinder side by adjusting the
valve (Fig.2.02, valve 3) clockwise.
By rotating anticlockwise the pressure
will be reduced (see page 34 for more
details). Pressurise to unfold until the
required pressure is achieved.
10. Draw the X-Press into work then
set the desired pitch of the machine
by adding or removing shims from
the drawbar cylinder or disc frame
adjusters. The chassis should ideally
be set to run slightly nose high. The
drawbar hydraulics may be worked in
float if desired.
2.5.2 Folding into the
Transport Position
1. Open the axle taps (Fig. 2.01, taps A
and B).
2. Operate the hydraulics to fully raise the
machine.
3. Fold the machine fully.
4. Lower the machine to maximise
stability while ensuring adequate
clearance for road transport.
5. Close the taps on the rear axle. Fit
the transport strap for transport safety.
The strap should be fitted from the
ground. Do not climb on the machine.
6. The machine is ready for transport. If
the X-Press is to be unhitched from
the tractor in the folded position the
parking stands should be lowered.
