2. Raise planter to fully raised position. With cam positioned as shown, adjust detent lever (lowering control) valve
in its mounting slots so there is 1/16" gap between stainless bushing and cam. Lower edge of cam must be above
pivot point of stainless bushing.
nOTe: while lowering planter, center cylinders should begin to retract while wing cylinders stay extended.
when toolbar becomes level, large radius of cam should cause arm to depress plunger on detent lever valve
allowing wing cylinders to start retracting.
3. Lower planter. If center of planter drops lower than wings, loosen set screws and rotate cam clockwise. If wing
cylinder begins to retract too early and wings drop lower than center of planter, rotate cam counterclockwise.
Adjust cam with planter in raised position.
4. After final adjustment, remove one set screw and drill a depression in cam activator shaft with a ¼" drill bit.
Reinstall set screw and repeat with second set screw. This prevents cam from slipping on pivot shaft.
1. Raise planter to field turn around position and check toolbar height is 39"-41". Adjust following procedure for
stroke limiter valve adjustment. Stroke limiter (height stop) valve must be correctly adjusted prior to adjusting
detent lever (lowering control) valve.
