Marker Adjustments
Folding Speed with Needle Valves
Refer to Figure 30
A needle valve controls the folding speed of markers that
are plumbed separately. The needle valve is near the rod
end of the marker cylinder.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Turn adjustment knob
clockwise to reduce folding speed or counterclockwise to
increase folding speed. Excessive folding speed could
damage markers and void the warranty.
Folding Speed with Sequence Valve
Refer to Figure 31
If markers are tied together with a sequence valve,
adjust folding speed with hex adjustment screws on the
sequence-valve body. There is one adjustment screw for
raising speed (1) and one for lowering speed (2). Identify
adjustment screws by markings stamped in valve body.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Turn adjustment screws
clockwise to decrease folding speed and
counterclockwise to increase folding speed. Excessive
folding speed could damage markers and void the
warranty.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.
Marker Disk Adjustment
Changing Disk Angle
Refer to Figure 32
If mark left by marker disk is not clearly visible, adjust
disk angle to make a wider mark. Loosen two 1/2 inch
bolts (1) holding disk assembly (2). Rotate disk assembly
as desired
