Working depth
Before making the adjustment:
Fully lower the machine using the hydraulic control device on the
tractor and advance approximately 1 metre.
Measure the working depth to the ground.
Adjust the working depth as follows:
Use the tractor's hydraulic control device to lower the machine to
the work position.
Switch off the tractor and secure it.
Basic working depth
setting
The working depth is set using the crank on the rotor.
Release the crank retainer on the rotor chassis and adjust the
working depth by turning the crank.
•
Basic setting: the tines lightly touch the ground.
After adjusting, secure the crank against turning using the retainer.
Adjust the working width on the second rotor in the same way.
Readjust the working depth to suit the field conditions if necessary.
Ten turns of the crank equate to a height adjustment of approx. 15 mm
on the tines.
After making the adjustment, use the retainer to secure the working
depth crank against turning.
The working depth can now be set at the rear rotor in the same way.
Further influencing factors for the working depth are:
•
The soil condition and stubble length.
•
The type and quantity of crop.
Tines that are set too low will soil the crop. The load on the rotor tines
and the drive is increased.
