Hydraulic marker functioning improperly Check all hose fittings and connections for air and oil leaks.
Check that the chain on the folding marker is slack when the marker is both
fully folded and unfolded. Add chain slack as necessary. Refer to Marker
Adjustments, “Adjustments,” page 34.
Check tractor hydraulic oil level.
Check all bolts and fasteners.
Check if needle valve is plugged; open valve, cycle markers, and reset the
needle valve if necessary.
Check that switches on control console are set properly. Refer to Field Oper-
ation, “Operating Instructions,” page 17.
Marker disk blade does not mark Check if the marker folding linkage and chain have enough slack to allow the
marker disk to drop in low spots. Maximum down float should be limited by
the slots at the rod end of the marker cylinder–not by the chain. Add chain
slack as necessary. Refer to Marker Chain, “Adjustments,” page 34.
Reverse blade to pull dirt in or throw dirt out depending on soil conditions.
Refer to Disk Adjustment, “Adjustment,” page 35.
An optional smooth blade is available through your Great Plains dealer.
