4. Adjustment / Operation
4.10 Adjusting Tine Depth
(CultiPress models only)
Crowd the machine rearwards until the
weight of the machine is on the rear DD
roll. Continue to extend the tilt rams until
they are at full stroke. Stop the tractor and
TURN OFF THE SHUT OFF TAPS AT THE
RAM PORTS. This will then allow access
under the machine. Once all tine have been
adjusted, ensure none is under or near the
machine open the shut off taps on the ram
ports and then lower the machine until the
working elements are on the ground.
4.10.1 Placing Tines Deeper
into Work
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 whilst at the same time extend the rear
roll cylinders. Remove the required number
of shims from the rear roll cylinders, if weight
is being support on the transport wheels it
may be necessary to add shims to the wheel
cylinders. Once the required amount of
shims have been removed from the rear roll,
pressure the circuit in the opposite direction
to draw the roll cylinders closed and then
draw the wheel cylinders closed. NOTE: it is
important to pressure the hydraulics until all
shims, with special note being made to the
wheel cylinders, are clamped tight. Making
sure there is no one 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 press will return to the previously
set pitch.
4.10.2 Lifting the Tines Out of
Work
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 whilst at the same time extend the rear
roll cylinders. Add the required number of
shims to the rear roll cylinders, if weight is
being supported on the transport wheels it
may be necessary to remove shims from the
wheel cylinders. Once the required number
of shims have been added to the rear roll,
pressure the circuit in the opposite direction
to draw the roll cylinders closed and draw the
wheel cylinders closed. NOTE: it is important
to pressure the hydraulics until all shims,
with special note being made to the wheel
cylinders, are clamped tight. Making sure
none 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.
4.9 Depth Control
With the wing cylinders fully extended and
the machine tilted back onto the rear roll the
machine is ready for setting.
On CultiPress models there are two main
methods of adjustment.
• Coarse adjustment can be made by
lowering or lifting the tines within the
mounting plates, this will give a +/-
25mm depth change per hole.
• Fine adjustment can me made by
adding or removing shims on the rear
roll cylinders.
On the X-Press models depth adjustment
is made in the same way as the FINE
adjustment method mentioned above.
