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.
Marker Extension
Marker extension needs to be adjusted once for the initial
YP825AR planter setup, and later only if changing row
spacing (including row shut-off for single-row operation
on a twin-capable planter).
1. Move the planter to a location where both markers
may be safely unfolded.
2. Lower the planter. Pull forward and lower rows into
ground.
Note: Due to the relatively steep arm angles of short
markers, extension measurements are likely to be
incorrect if the main tool bar is not at normal
operating height (26 inches).
