Refer to Figure 66
The YP4025A 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
delivery is to begin.
2. Loosen bolt holding switch bracket to plate .
3. Move bracket forward or rearward so that switch
toggle arm
makes contact with rear cross tube .
4. Tighten nuts.
Note: Switch is in “Neutral” position when planting.
Switch is “Activated” when raised.
