4.7 Pitch Control
Pitch control on the Simba CultiPress is
governed by the quantity of shims fitted to
the depth stops attached to the drawbar
cylinders. Increasing the number of shims
will lift the front of the chassis when lowered
into the work position. Ensure that equal
quantities of shims are added or removed
from each cylinder.
Running the CultiPress level allows the
front and rear press rings to give an even
consolidation and clod crushing action, with
the sprung leaves of the levelling board
aiding the clod crushing action, aligning the
clods for the front row of rings.
Running the machine significantly nose
down or raised will reduce the load on the
rear axle leading to loss of drive of the axle
and then blockage, together with a reduced
consolidation effect.
If any roll axle starts to block regularly, this
is generally an indication that the roll axle
is not tight. Failure to keep the axles tight
results in loss of drive between each pair of
rings allowing rings to turn individually on
the axle. Should this occur the axle must
be tightened immediately to prevent any
damage occurring to the axle shaft.
If the roll axles start to block regularly this
may also be an indication that the ground
conditions are too wet for the CultiPress to
be effective.
In practice it is possible to use the CultiPress
on ground conditions that are unsuitable to
achieve the desired effect, and it is usually
possible to operate the machine without
regular blockage under such unsuitable
conditions, assuming that the axles are tight
and rings smooth.
As such, especially under wet conditions,
it is advisable to check on the cultivation
effect of the CultiPress. Often the use of the
press 12 - 24 hours after the disc or longer
following the plough gives a far superior
surface consolidation effect.
When the CultiPress is used tilted onto the
rear row of rings the loading on the disc
cultivator or tractor drawbar is increased.
This will cause the rear of the disc to dig
deeper moving the rear gang to the right.
Shortening disc harrow levelling springs
should allow allow a disc harrow to pull
straight again. Equally, increased tractor
drawbar loadings will deepen wheelings
requiring more effort to eradicate these.
It is not necessary to tilt the CultiPress onto
the transport wheels during headland turns
whether the machine is used independently
or in tandem with a disc cultivator.
Fully extending the drawbar
cylinders and then reversing into
the headland furrow could lead to
damage of the cylinders.
