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. 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 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 disc and X-Press combination.

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. Normally,

the X-Press should be tilted sufficiently for the

discs to clear the ground (at which point the

rear axle wheels will still be clear of ground

contact).

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.
