4.13 Transport wheel
adjustment
If when in work the center of the machine
begins to dip or the machine enters a wet
spot it is possible to support weight on the
middle transport wheels.
4.13.1 Adjusting the Transport
Wheel Height
Operate the main tilt circuit (red) to extend
the cylinders and support the weight of the
machine on the rear roll, continue to extend
the cylinders until all tines/discs are out of
work. Now, operate the wheel cylinder circuit
(blue). This will push the wheel cylinders
open (the rear roll cylinders will also extend
at the same time). Add/remove the required
number of shims from the wheel cylinders
then operate the circuit in the opposite
direction to close the wheel cylinders. NOTE:
ensure the shims on the wheel cylinders and
the rear roll are clamped up tight. Making
sure no one is near the machine lower the
machine back into the work position. As long
as the power to the limit switch is still on then
the pressure will return to the previously set
pitch.
4.11 Out-Rigger Wheel
Adjustment
When in work these units are designed to
help support the wing tips. After making
any adjustment to the working depths it is
important to check that both of these units
are still in light contact with the soil surface.
Adjustment is made by tilting the machine
back onto the rear roll and extending or
contacting the top link bar. Add or remove
shims to give a solid lock. The side mounted
link bar should be tight at all times.
4.12 Levelling Boards
(if
fitted)
With the press set level rotate the levelling
boards until they are carrying soil. The
levelling boards will need to run slightly
higher during first pass operations especially
on ploughed land where large clods may
not be able to pass under or between the
sprung leaves.
The boards need to carry a certain amount
of soil to effect a levelling operation and also
to give a clod to clod crushing action. Use
the hydraulics to rotate the levelling boards
to carry more or less soil when levelling the
headland troughs for example.
When reversing the press into corners
ensure that the levelling boards are fully
rotated (fully meshed into DD’s) and the
machine is tilted fully onto its rear roll so
all ground engaging elements are clear of
the ground. Failure to do so could result in
serious damage.
