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).
