4. Adjustment / Operation
4.4 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 Double Press should be run with the
chassis level front to rear by extending the
drawbar cylinder to the necessary position.
The cylinder 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 Double Press onto
the transport wheels during headland turns
whether the machine is used independently
or in tandem with a disc cultivator. Normally,
the Double Press should be tilted sufficiently
onto the rear roll for the tines to clear the
ground (at which point the rear axle wheels
will still be clear of ground contact).
