Driving speed

The Press can be driven at speeds of up to
14 km/h.

This depends on the field conditions (type of
soil, surface trash, etc.).

Drive more slowly if the conditions are difficult
or a firmer finish is required.

Turning:

Before turning, the machine should
be eased out of work while driving.
Likewise, it should eased back into
work once the turn has been
completed.

When reversing the (ie. into the
corner of a field) the machine should
be tilted onto its rear roll. On
machines fitted with levelling boards
it is imperative that the levelling
board cylinders are fully extended
(intermeshing the sprung leaves with
the DD roll) before reversing.
Serious damage can occur if the
levelling board leaves are in contact
with the soil when reversing the
machine.

4.14 Adjusting Disc Angle

(X-Press model only)

If the machine is fitted with levelling boards
you first turn the divert tap to the angle setting.

When stationary crowd the machine onto the
rear roll to ease the working elements from
work. Operate the hydraulics (orange/green)
so that the disc angle rams open to full stroke.
Add/remove shims as required. Once the
shims are set reverse the hydraulics to nip
the shims tight. This has now set the maximum
cut angle of the discs. In work it is possible to
relieve this angle (straighten the cut) if a
blockage occurs and return to this setting.
NOTE: It is not possible to operate both the
levelling boards and gang angle on the move.
