WARNING!
Do not place any part of body under implement while making
adjustments.
A height switch turns seed metering off when the imple-
ment is raised. The switch is on the left-hand, dual gauge-
wheel-arm pivot tube. Seed will be metered if the switch is
extended (off cam). Metering will stop when the switch is
compressed (on cam). To adjust the height at which seed
metering is turned off, follow these steps.
1. Lower the implement until it is at a height where you
want seeding to start (usually just above the ground).
2. Turn off the tractor and remove the key.
3. Loosen the cam clamp on the pivot tube and turn until
the roller is just starting to make contact with the ramp
surface. See Figure 3-9.
4. Tighten the clamp securely.
5. Raise the implement fully and check that the switch is
compressed as shown in Figure 3-10.
