Dual Marker Speed Adjustment
Crushing and Sharp Object Hazards:
Never allow anyone near the planter when folding or
unfolding the markers. You may be injured if hit by a folding or
unfolding marker. Markers may fall quickly and unexpectedly
if the hydraulics fail.
Refer to Figure 74 and Figure 75
Adjust folding speed for dual markers with hex
adjustment screws on the sequence valve body. The
valve sequence body is located on top of the left wing
frame.
Loosen jam nuts before making adjustments.
There is one adjustment screw for unfolding speed
and one for folding speed
. You can identify adjustment
screws by markings stamped in valve body.
Turn adjustment screws clockwise ( : slower) to
decrease [un]folding speed and counterclockwise
( : faster) to increase [un]folding speed.
With tractor idling at a normal operating speed, adjust
marker folding to a safe speed. Excessive [un]folding
speed could damage markers and void the warranty.
After adjusting the folding speed, tighten jam nuts on hex
adjustment screws to hold settings.
