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 markers do not alternate, check tractor flow controls and set to maximum oil
flow. If problem still exists:, disassemble valve and check for contamination or
spool damage.
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 cylin-
der is fully extended.
The blade may be reversed to pull dirt in or throw dirt out depending on soil condi-
tions.
