Disc-O-Mulch settings for firm ground
Tractor 3-point hitch in floating position with no position control
Adjusting the working depth of the 1st row of disks:
Alter the length of the tractor's top link. Shortening the top link increases the depth of the first row of
disks.
Warning:
the working depth apparent when the machine has stopped is often less than when the
machine is in movement. At speed, the machine's pressure on the top link and the percussion effect of
the 3D safety system increases the working depth. You should therefore check the working depth by
examining the profile of the topsoil in an area worked at speed and not at the edge of the field.
Adjusting the working depth of the 2nd row of disks:
The second row of disks is controlled by the rear roller with the help of the multistops.
3.1.5.4.
Disc-O-Mulch settings for soft ground
On soft ground, the pressure of the Disc-O-Mulch on the tractor's top link can make the machine
unstable. You should therefore modify the machine's settings.
Disconnect the tractor's top link from the Disc-O-Mulch.
You must then accurately adjust the
working depth of the 1st row of disks using the tractor's 3-point hitch position control.
When
the required high speed working depth is found, stop the tractor and reconnect the tractor's top link to
the Disc-O-Mulch in the floating position. The coupling pin must be in the centre of the elongated hole.
If the machine is still unstable,
lateral stabilising wheels
must be fitted. These wheels will prevent the
machine from rocking from left to right and going into vertical resonance. These are stabilising wheels
and not position control wheels. They must be adjusted to approximately 2 cm above the ground.
