Circuit Operation - All Marker Types
The marker cylinders are connected to one tractor remote
hydraulic circuit.
NOTE: On models with lift assist wheels, the circuit
operates both the marker and planter lift assist
functions.
The markers alternately raise and lower each time the
planter is raised and lowered.
If both markers must be lowered, lower the first marker to
the ground. When the first marker is all the way down,
move the hydraulic lever to the RAISE position. Hold the
hydraulic lever in the RAISE position just until the marker
cylinder for the first marker begins to move. Shift the lever
to the LOWER position to lower the second marker.
NOTE: If a marker begins to raise, it cannot be lowered
until after it is fully raised.
On tractors with pressure detent remote valves,
the control lever will have to be held until marker
is fully raised or lowered.
