Working depth
When working, the machine is raised and lowered hydraulically. The
machine is lowered as far as the preadjusted depth. The basic setting
for the working depth is adjusted using an adjusting screw on the
chassis cylinder.
Checking the
working depth
Check the preset working depth as follows:
Fully lower the machine using the tractor's hydraulic control device.
Switch off the tractor and secure it.
Check the working depth to the ground.
The ideal working depth depends on several factors. Decisive, among
others, are:
•
The soil condition and the stubble length.
•
The type and quantity of fodder
If the tines are positioned too low, the crop is contaminated and the
stress and wear on the tines, and thus on the drive, increases.
If necessary, adjust the working depth to the field again.
Adjusting the
working depth
The chassis cylinder is used to adjust the chassis end stop in the work
position. Start with a horizontal chassis basic setting at a hitch height
of 400 mm. The chassis pitch depends on the ground conditions and
the crop. Adjust the working depth as follows:
Use the tractor's hydraulic control device to move the machine into
the headland position.
Switch off the tractor and secure it.
Close the ball valve.
Release the adjusting nut below the chassis using the catch and
use the adjusting nut to adjust the working depth.
Use the catch to prevent the adjusting nut from moving.
Switch on the tractor.
Lower the machine.
Switch off the tractor and secure it.
Check the working depth and readjust it if required.
Two turns of the adjusting nut change the height by 15 mm on the
tines.
