Implement Lift Switch Adjustment
A switch on the drill turns seed metering off (via the
electric clutches) when the drill is raised. To adjust the
height at which seed metering stops, follow these steps.
1. Do not place any part of body under implement while
making adjustments.
2. Locate the lift switch on the left hand rockshaft.
3. Lower the implement until it is at a height where
seeding should start (usually just above the ground).
Securely support frame at this height with jack
stands or blocks.
4. Turn off the tractor and remove the key.
5. Loosen the cam clamp on the rockshaft and turn
until the switch roller is just starting to make contact
with the ramp surface .
6. Raise the implement fully and check that the switch
is compressed. If adjustments are made to hydraulic
coulter depth, re-check switch engagement.
If coulter depth is adjusted, re-check lift switch
operation.
