Machine Operation
ROw MARKER SPEED ADJUSTMENT
Flow control valves located in the marker sequencing/flow
control valve assembly control lowering and raising speed of
markers. One flow control valve sets lowering speed of both
markers and one sets raising speed of both markers. To adjust
marker speed, loosen jam nut and turn control(s) clockwise,
or IN to slow travel speed and counterclockwise, or OUT, to
increase travel speed. Flow control(s) determine amount of oil
flow restriction through valves, therefore varying travel speed of
markers. Tighten jam nut after adjustments are complete.
NOTE: Backing flow control valve out too far can cause the o-ring seal on valve to fail when hydraulics are operated.
NOTICE
The flow controls should be properly adjusted before the marker
assemblies are first put into use. Excessive marker travel speed can
damage the marker assembly.

To avoid serious injury or death, care must be taken when operating
row markers around overhead power lines.
NOTE: when oil is cold, hydraulics operate slowly. Make sure all adjustments are made with warm oil. Do not
overtighten lock nut.
NOTE: On a tractor where oil flow can not be controlled, the rate of flow of oil from tractor may be greater
than rate at which the marker cylinder can accept oil. Tractor hydraulic control lever will have to be held until
cylinder reaches end of its stroke. This occurs most often on tractors with open center hydraulic systems. On
tractors with closed center hydraulic systems, the tractor’s hydraulic flow control can be set so the tractor’s
detent will function properly.

Always stand clear of marker assemblies and blades when planter
is operating.

The single valve marker system uses a sequencing valve which directs hydraulic flow to operate the markers
alternately. Each time a marker is raised, the sequencing valve will direct flow to lower the opposite marker.
Both markers can be used at the same time if desired. To do this, lower the planter and the marker that has been
selected. Move the tractor SCV control to the raise position and immediately return it to the lower position. This will
shift the marker control valve and the remaining marker will be lowered.
