4.5 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. 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 X-Press should be run with the
chassis slightly nose high by extending the
drawbar cylinders to the necessary position.
In practice it is possible to use the X-Press
on ground conditions that are unsuitable to
achieve the desired effect, and it is usually
possible to operate the press 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 machine.
On machines fitted with a DD700 roll it is
not necessary to tilt the X-Press onto the
transport wheels during headland turns
whether the machine is used independently
or in tandem with a disc harrow. The X-Press
can be tilted onto the DD700 roll until the
discs clear the ground (at which point the
rear axle wheels will still be clear of ground
contact). On machines fitted with a DD Light
roll the machine should be turned on the
transport wheels to avoid damage to the roll
(ensure that the DD Light roll is clear of the
ground when turning).
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.
