4. Adjustment / Operation
4.5 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 X-Press should be run with the chassis
level to slightly tail low. 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 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 X-
Press.
The mounted 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 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.
