31 X-Press
Operating Instructions
4.9 Work Instructions
Driving speed
The X-Press can be driven at speeds of up
to 12 km/h.
This depends on the field conditions (type
of soil, surface trash, etc.).
Drive more slowly if the conditions are diffi-
cult or a firmer finish is required.
Turning:
Before turning, on machines fitted
with a standard DD700 roll, the
machine should be eased out of
work onto the rear roll while driving
and should be eased back into work
once the turn has been completed.
On machines fitted with a DD Light
roll the machine should be eased
out of work onto the transport
wheels before turning. Under no
circumstances should the DD Light
roll be in contact with the soil whilst
turning the machine.
4.10 Checks
The working quality depends on the
adjustments and checks made prior to and
during work, as well as on regular servicing
and maintenance of the machine.
Before beginning work it is therefore
important to carry out any necessary
servicing and to lubricate the machine as
required.
Checks prior to, and during
work:
• Is the machine correctly hitched up and the
coupling device locked?
• Have the hydraulic lines been connected
according to the colour coding?
• Is the machine in a level operating position
and the working depth set correctly?
Working Elements
• Are the discs and other cultivation tools in
a serviceable condition?
• Are the scrapers still operable, so that the
rolls do not jam?
4.8 Adjusting Disc Frame
Depth
Adjustment of the disc frame depth is
achieved by lengthening or shortening the
adjusters as required in combination with
raising or lowering the disc frames relative
to the DD roller by adding or removing
drawbar shims (for example, to increase
disc depth remove drawbar shims and adjust
the turnbuckle as required). Once set, the
adjusters should be locked by adding shims
to the lower end thread and tightening.
To change the settings it is advisable to lift
the disc frames just clear of the ground so
that the adjusters can be lengthened enough
to fit the amount of shims required. When
the shims have been fitted the machine can
be lowered, making it easier to tighten the
adjuster against the shims.
Parking the Machine
In order to avoid damage as a result of
moisture, the machine should be parked, if
possible, indoors or under cover.
When manoeuvring the machine,
pay attention to your surroundings.
Ensure that nobody (children!) is
in the manoeuvring area.
•Park the machine on level and solid ground.
•Fit wheel chocks.
• With the machine raised move the parking
stands into position.
• Lower the machine onto the parking stands
ensuring that it is stable.
• Remove the drawbar pin and drive forward
slowly until hitch is clear of tractor drawbar.
• Lower the drawbar to the ground.
• Switch off the tractor.
• Disconnect hydraulic lines from the tractor.
