4. Adjustment / Operation
4.6 Work Settings
In work the wing cylinders should be fully
extended. The gangs are able to float over
any undulations on the ground due to their
floating frames.
Optimum performance has been found
to be achieved when the press roll rings
have worn away the painted finish leaving
a smooth shiny surface. When the press
roll rings are new or rusty, soil may tend to
pick up on the surface and blockage may
occur, this will reduce when the rings are
shiny again.
The CultiPress should be run with the
chassis level front to rear by extending the
drawbar cylinders to the necessary position.
The cylinders should not be over extended
as this will remove the load on the front row
of rings which could lead to reduced drive
and hence blockage of the axles.
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. Normally,
the CultiPress should be tilted sufficiently for
the tines and levelling boards to clear the
ground (at which point the rear axle wheels
will still be clear of ground contact).
General Rules when Setting
the Simba CultiPress
• Run the chassis horizontal to give
even drive on both sets of rings.
• Run slightly tail low to give increased
clod cutting and consolidation in
harder conditions.
• In trashy conditions the use of the
levelling board may be limited due to
raking trash.
• Increase the rake angle of the levelling
board in spring time operation to carry
more soil for levelling.
• Reduce rake angle on levelling board
to hold soil and rub clod against clod in
harder conditions. This will also align
clods with the DD rings facilitating
better cutting.
4.6.1 Levelling Boards
With the chassis set level, lower the levelling
boards until they are carrying soil. The level-
ling boards will need to be set higher during
1st 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 raise and lower the boards
to carry more or less soil when levelling the
headland troughs for example.
When reversing the CultiPress into corners
when working headlands ensure that the
levelling boards are fully raised and the
machine tilted onto the rear set of rings far
enough to allow the lower ends of the sprung
leaves to clear the ground.
