The YP3025A Planter includes a sensing switch that
signals the seed monitor (and activates the optional
hydraulic meter drive), when the planter is lowered for
planting. The switch is located at the rear cross tube on
the planter’s left side.
Although factory-preset for typical planting conditions,
Great Plains recommends adjusting this switch for your
exact field conditions and planting depth.
Crushing Hazard:
Exercise extreme caution when adjusting the switch.
1. Lower the planter to the height at which seed deliv-
ery is to begin.
2. Loosen bolt holding switch bracket to plate .
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.
