Troubleshooting/FAQ
Hydraulic control is not working:
•
Check that there is no pressure in the hoses before
connecting them to the tractor.
•
Check that the hoses are connected to the tractor.
•
Check that the hoses are connected to the correct
connectors in pairs.
•
Check that the wheel circuit shutoff valve is open.
•
Check that the tractor's valve block is in a double-acting
position.
The lifting and lowering functions of the frontboard and wing sections
work simultaneously:
•
Check that the change valve control rod is connected
and that it is not bent.
•
Check the control rod adjustment.
The working depth is creeping:
•
Balance the wheel cylinders by extending the piston
rods fully and keeping the pressure on for 15 seconds
for a couple of times with the wheel circuit hydraulics.
•
Fully extend the piston rods of the wheel cylinders and
disconnect the hoses from the tractor. If the cultivator lowers
over 10 mm, there is an internal leak in the cylinders. If this
is the case, please contact the manufacturer.
The frontboard/rearboard is not moving in line:
•
Balance the cylinders (see above). They must move in line.
If not, check the end pieces of the cylinders and adjust.
•
If the alignment is lost again, there is an internal leak
in the cylinders. If this is the case, please contact the
manufacturer.
•
The frontboard/rearboard is creeping during harrowing.
Connect the hose pair to another coupling pair in the tractor.
If the problem persists, please contact the manufacturer.
