OPERATION

Ploughing with hydraulic control
So that the hydraulic control functions properly, the following must
be observed.
- Position upper link (1) so that the attachment point (P1) on the
plough during operation is somewhat higher than the attachment
point (P2) on the tractor.
Pinning the upper link
LL, RL = Pinning position for securing lower link
RL = Pinning position for securing upper link
Details see chapter „ATTACHING TO THE TRACTOR“.
- During operation the plough should lie lengthwise as parallel as
possible to the ground surface.
- The working depth is set with the lifting gear via the servo-valve
firstly.
Depending upon the hydraulic control model, varying ground
resistance when ploughing is passed on to the control servo-valve
via the upper link (1) or both the lower links. The relevant impulse
is then converted causing the lifting gear to lift or lower.
An example: Securing upper link
The plough penetrates deeper into the ground.
This causes the pressure on the control servo-valve via the upper
link to become greater.
As a consequence, the control valve remains switched to lift until
the set working depth is reached again.
Note:
Follow the tractor manufacturer’s operating manual also.
