Actuator for setting a seed depth for a row unit on a planter

Abstract:

An agricultural planter row unit has a gauge wheel supported by a gauge wheel arm, to control planting depth. An actuator drives movement of a mechanical stop that bears against a gauge wheel support arm to position the gauge wheel support arm to obtain a desired planting depth. A seed depth control system receives an operator input, from an operator compartment of a towing vehicle, and automatically controls actuation of the seed depth actuator.
