Height Switch Adjustment
s/n B1003V+
Refer to Figure 134
The YP3010HDP/3020P/3025 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 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 rear cross tube .
4. Tighten nuts.
Note: Switch is in “Neutral” position when planting.
Switch is “Activated” when raised.
Note: 30in single-row planters do not have Y-tubes. Go
meter to meter, open clean-out door and blow out
seed.
