4.7 Work Settings
Optimum performance has been found to
be achieved when the DD Light roll rings
have worn away the painted finish leaving
a smooth shiny surface. When the DD Light
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 X-Press should be run with the
chassis level to slightly tail low. In practice
it is possible to use the Simba X-Press on
ground conditions that are unsuitable to
achieve the desired effect, and it is usually
possible to operate the DD Light roll without
regular blockage under such unsuitable
conditions, assuming that the roll assemblies
are tight, the scrapers correctly adjusted and
rings smooth. As such, especially under
wet conditions, it is advisable to check on
the cultivation effect of the Simba X-Press.
The mounted Simba X-Press should be lifted
fully clear of the ground for all headland
turns. Turning with the disc units or roller on
the ground could lead to damage of these
components.
In work, the tractor lower link arms may be
run in float in order to allow the machine to
follow undulations in the soil.
General Rules when Setting
the Simba X-Press
• The lighter the land conditions the less
the disc angle required and the forward
speed can be increased.
• The wetter the land conditions the less
the disc angle required and the forward
speed will need to be decreased.
• Heavier land will require more of a disc
angle and a slower forward speed.
• The more the trash the less the angle
on the discs and forward speed will have
to be decreased.
• On ploughed land reduce the disc angle
to give a cutting/chopping action.
• In hard conditions increase the disc
angle to increase penetration.
