Working depth
Adjust the working depth as follows:
Fully lower the machine using the hydraulic control device on the
tractor and advance approximately 2 metres (7 ft).
Shut off the engine, set the parking brake, remove the ignition key
and secure the tractor against rolling away.
Check the working depth to the ground.
Adjusting the
working depth
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.
• Ten turns of the crank equate to a rotor tine height adjustment
of about 15 mm (0.6 in). The thread is left-handed.
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.
Tines that are set too low will soil the crop. The load on the rotor tines
and the drive is increased.
• If necessary, adjust the working depth to the field again.
\ WARNING
Never set the tines too deep
If the tines are set too deep:
• The tines are overstressed.
• The tines will soil the crop.
• This can result in damage to the machine.
