Planter is shown in raised position for clarity of height
switch. 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 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.
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 U-bolt holding switch bracket to link .
3. Move bracket forward or rearward so that switch
toggle arm
makes contact with tool bar .
4. Tighten nuts.
Note: Switch is in “Neutral” position when planting.
Switch is “Activated” when raised.
