4.10 Starting Settings
This section details the recommended start-
ing settings for the Solo. These settings can
then be used as a base for further adjustment
in order to get the optimum performace from
your machine.
Ensure all settings from the left and right hand
sides of the machine mirror each other.
4. Adjustment / Operation
4.9 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 Solo 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 Solo 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 Solo.
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.
In normal operation the machine should be
hydraulically drawn onto the drawbar shims,
however, it is permissibleto operate the lift
circuit in float in order to allow the implement
to follow contours as the tractor drawbar drops
(eg. over the brow of a hill).
Drawbar Cylinder
The drawbar cylinder shim set-
tings 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.
