2.6 Preceding & Trailing
Implements
2.6.1 Hitching a Disc Harrow
to the CultiPress
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
CultiPress 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 CultiPress 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 CultiPress drawbar above the
disc drawbar (200mm approx.). Depth
control shims may need to be removed.
6. Raise the disc harrow to the same height
as the CultiPress drawbar then reverse
the disc harrow to couple the two
machines together.
7. Fit the drawbar pin.
8. Operate the hydraulics to lower the rear
axle and drawbar, tilting the CultiPress
onto the road transport wheels. Fully
extend the drawbar cylinders.
9. Fully raise the levelling boards.
10. Operate the hydraulics to fold the wings.
11. Operate the hydraulics to lift the disc
harrow into the transport position.
12. Fit the disc harrow transport straps.
13. Fit the CultiPress wing transport strap
to tie the two wing sections together.
14. Ensure that parking stands are locked
up in their work position.
When the CultiPress is used in tandem with
a disc harrow the disc should be set to the
operators manual i.e. front disc gang to be
50mm closer to the ground than the
corresponding disc blade on the rear gang.
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 CultiPress is applied to the drawbar of
the disc harrow.
The frame may be levelled by altering the
rearward tilt of the CultiPress to increase or
reduce the loading on the disc rear drawbar.
2. Transportation / Installation
2.6.2 Transporting a
CultiPress 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 CultiPress 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
CultiPress is transported up steep gradients
