Initial Marker Setup (Option)
Marker Speed Adjustment
You may be injured if hit by a folding or unfolding marker.
Markers may fall quickly and unexpectedly if the hydraulics
fail. Never allow anyone near the planter when folding or
unfolding the markers.
Refer to Figure 173 and Figure 174
Adjust folding speed for dual markers with hex
adjustment screws on the sequence valve body. The
valve sequence body is top left center section, near front.
Loosen jam nuts before making adjustments.
There is one adjustment screw for fold-out speed and
one for fold-down speed . You can identify adjustment
screws by markings stamped in valve body.
Turn adjustment screws clockwise (S: slower) to
decrease folding speed and counterclockwise (F: faster)
to increase folding speed.
With tractor idling at a normal operating speed, adjust
marker folding to a safe 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.
