Planter is shown in raised position for clarity of height
switch. The YP3025A Planter includes a sensing
switch
that signals the seed monitor (and activates the
optional hydraulic meter drive), when the planter is low-
ered for planting. The switch is located at the front of the
right link connecting the rockshaft and rear axle.
Although factory-preset for typical planting conditions,
Great Plains recommends adjusting this switch for your
exact field conditions and planting depth.

1. Lower the planter to the height at which seed deliv-
ery is to begin.
2. Loosen U-bolt holding switch bracket to link .
3. Move bracket forward or rearward so that switch tog-
gle arm
makes contact with tool bar .
4. Tighten nuts.
Note: Switch is in “Neutral” position when planting.
Switch is “Activated” when raised.
