Implement Lift Switch Adjustment
Refer to Figure 41
A switch on the drill turns seed metering off when the drill
is raised. To adjust the height at which seed metering is
turned off, follow these steps.
1. Do not place any part of body under implement while
making adjustments.
2. Locate the lift switch at the right rear lift assist
parallel arms.
3. Lower drill completely and set drill valve to Field
position.
4. Loosen switch bracket bolts and slide switch
assembly up or down until actuator makes contact
with the lift arm and switch is reliably toggled on (up).
5. Tighten bolts.
Note: If adjustments are made to hydraulic coulter depth,
re-check switch engagement.
Note: For reference, the ADC2350 lift switch wiring is:
Black (switch COM) to black (extension)
Red (switch N.C.) not connected
Green (switch N.O.) to red
Circuit open when drill is raised.
