See “Cleaning Out Meters” on page 56.
4. Set planting rate. See “Planting Rate” on page 38.
5. Set tractor 3-point hitch control for depth control

hitch movement may cause changes in row unit
depth resulting in uneven depth control.
6. Set tongue height with planter lowered, to 46in. See
“Leveling Frame Side-to-Side” on page 17.
7. Turn on fan. Set tractor hydraulic flow control to

ends and for other short-radius turns. Planting will
stop automatically as planter is raised.

tor 3-point.
