2.6 Preceding & Trailing
Implements
2.6.1 Hitching a Disc Harrow
to the X-Press
1. Remove the transport straps from the
disc harrow, exercise great CARE
when extending the axle cylinder.
2. Reverse the disc harrow up to the X-
Press drawbar ensuring that the two
drawbars are aligned allowing a slight
clearance to enable the machines to be
coupled together.
3. Lower the disc harrow to the ground.
4. Connect the four hydraulic hoses from
the X-Press into the disc harrow rear
outlets ensuring that the two wing hoses
are together and the two drawbar
cylinder hoses are together. Ensure that
the folding circuits and lift drawbar
circuits are coupled correctly.
5. Raise the X-Press drawbar above the
disc drawbar (200mm approx.).
6. Raise the disc harrow to the same height
as the X-Press drawbar then reverse
the disc harrow to couple the two
machines together. A pair of additional
taps (P00774) may be required in the
lift circuit of the disc harrow or the X-
Press. This will isolate the drawbar
circuit.
7. Operate the hydraulics to lower the rear
axle and drawbar, tilting the X-Press
onto the road transport wheels. Fully
extend the drawbar cylinders.
2. Transportation / Installation
2.5.3 Following Harrow
Operation
Into Work:
1. Arrive in field and unfold machine
according to operating instructions
2. Whilst at rear of machine closing axle
taps move Pins (qty 2) from front most
holes (by lug) to rear hole.
3. Remove pin on outer quadrant plate and
re-position in the highest possible hole
for storage.
4. Driving forward will flip the harrow out
into a work position
5. When turning in work, tip the machine
rearwards into the roll. Reversing the
machine in this position allows the
harrow to flip temporarily into the
transport position. Driving forwards
again flips the harrow back into work.
Turning in work must only be on the
rear roll. Attempting to lower the
transport axle with the harrow in the
work position will seriously damage
the following harrow components.
Into Transport:
1. Tilt the X-Press onto the rear roll and
reverse the machine slightly as if
performing a headland turn.
2. Whilst at the rear of the machine opening
the transport axle taps, move the harrow
clamp pins (qty 2) from the front holes
to the rear holes by the lugs.
3. Use the pin in the outer quadrant plate
to the lowest position permitted that it
will lock the harrow arm down.
4. Continue folding the X-Press in
accordance with the operating
instructions.
