You can adjust the amount of travel for the contact wheel
by loosing the jam nuts and lengthening or shortening
the threaded rod.
Note: This adjustment controls the timing of the seed
meter drive when raising and lowering the planter.
Increasing the gap between the tires causes seed
flow to start and stop with the planter at a lower
height. Decreasing the gap will cause seed flow to
start and stop at a higher position.
Note: Be sure to check for springs bottoming after making
this adjustment.
