The working depth is controlled hydraulically:
•
Check that the hoses are properly connected (+/–). Connect the
hoses marked with the same colour to the same tractor valve.
•
Fully retract the cylinder piston rods of the wheel hydraulics with
the wheel circuit valve A–. The line is indicated in red in the figure.
•
Select the control valve for the depth control circuit (the line
indicated in blue in the figure) and fully retract the piston rods
with valve B–. Then run the piston rods out with valve B+ until
the desired working depth is reached. You can check the
working depth from the working depth indicator.
•
The working depth is now set. You do not need to use the depth
control valve B-B unless you want to adjust the working depth.
The cultivator is lifted and lowered with the wheel circuit valves
A+ and A–. The line is indicated in red in the figure
.
Hose markings: Red = A-A = Wheel hydraulics
Blue = B-B = Depth control
The working depth must be measured from harrowed soil behind the cultivator and
adjusted separately for each field and crop.
The working depth can be adjusted with valve B-B when driving.
The actual depth must always be checked by measuring
harrowed soil behind the cultivator.
Take measurements for each section.
