4.8 Starting Settings
This section details the recommended
starting settings for the Simba SLD. These
settings can then be used as a base for
further adjustment in order to get the
optimum performance from your machine.
Ensure all settings from the left and right
hand sides of the machine mirror each other.
4.7 Work Settings
In work the wing cylinders should be fully
extended. A simple pressurised hydraulic
circuit automatically sets itself as the wings
are unfolded.
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 Simba SLD should be run with the
chassis level by extending the drawbar
cylinder to the necessary position and
adding shims as appropriate. In practice it
is possible to use the Simba SLD on ground
conditions that are unsuitable to achieve
the desired effect, and it is usually possible
to operate 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 Simba SLD.
Generally a forward speed of 5-7 mph
(8-11 kph) will achieve optimum results,
maximising inversion and burial. Speeds
in excess of those stated above will tend
to give a deterioration in the quality of the
work. This may be seen as a ridge and
trough effect across the work surface due
to soil being thrown too far by the leading
discs, the rear discs then are unable to turn
enough soil back.
Drawbar Cylinder
The drawbar cylinder shim
settings are subject to the
tractor drawbar height. As such,
the shim settings shown above
are intended as a suggestion
only. The machine should be
set to run with the chassis level.
