Troubleshooting
Problem
Solution
Hydraulic marker functioning
improperly
Check all hose fittings and connections for air and oil leaks.
Check tractor hydraulic oil level.
Check all bolts and fasteners.
If needle valve is plugged; open valve, cycle markers, and reset the needle valve.
Blade does not mark
The maximum marker down float is limited by the slot in the pivot link. If the blade does
not drop down to follow depressions in the field, make sure the marker cylinder is fully
extended.
The blade may be reversed to pull dirt in or throw dirt out depending on soil conditions.
