2.7.4 Hitching a Rear Roll to
the X-Press
Follow procedure 2.4 (page 16) to couple a
tractor to the X-Press. Once the tractor is
safely connected to the implement and in its
folded setting, raise the machine fully clear
of the ground.
1. Reverse the X-Press up to the roller.
2. Align the X-Press and roller drawbars,
lower the X-Press to the ground and
depressurise the lift hydraulics.
3. Raise / lower the axle as required
to align the respective machines‘
drawbars and couple together.
4. Couple the rear roll to the lift circuit of
the X-Press, ensuring that the hoses
are connected to the corresponding
circuit on the trailing machine.
5. Couple the rear roll wing (fold) circuit
to the wing (fold) circuit of the X-Press.
6. Fully raise the X-Press and the roll
clear of the ground.
7. Check that all transport straps / devices
are fitted.
2.7.2 Transporting an X-Press
Towed Behind a Disc Harrow
With both machines in the transport position
i.e. raised and folded, the top frame of the
disc harrow should be slightly nose down
or horizontal even when the downward load
from the X-Press is applied to the drawbar
of the disc harrow. The top frame should
NEVER be tail low in transport as this will
give a high negative loading on the tractor
which could lead to loss of traction to the
rear wheels.
Extreme caution must be taken when the
X-Press is transported up steep gradients
and across side slopes. On the wide models,
higher drawbar loading can be achieved by
shortening the drawbar cylinder.
Prior to leaving the field to travel on a public
highway ensure that any clods of soil are
removed from the machine to prevent them
from fouling the road.
MAXIMUM ROAD TRANSPORT SPEED 16
MPH (25 KPH).
2.7.3 Changing from Work
to Road Transport (X-Press
Towed Behind a Disc Harrow)
1. Remove the disc harrow wing locking
bolts.
2. Operate the hydraulics to raise the disc
and X-Press.
3. Operate the hydraulics to fold the
wings on both the disc harrow and the
X-Press.
4. Fit the transport straps to both
machines.
It may be necessary to shorten the levelling
springs until the top frame of the disc harrow
is horizontal or slightly nose down before
moving the machines.
Shortening the X-Press drawbar
cylinder will increase the loading
on the rear of the disc frame. If
necessary this can be used to
level the disc top frame for road
transport.
