  • Actuator for setting a seed depth for a row unit on a planter
    Patent number: 10827663
    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.
    Type: Grant

  • Calibrating an actuator for setting a seed depth for a row unit on a planter
    Patent number: 10779462
    Abstract: A planter row unit is positioned so a gauge wheel and an opener are in a known position relative to one another. A planting depth actuator that travels along an extent of travel to change a relationship between the gauge wheel and opener is positioned at one end of its extent of travel, out of engagement with a gauge wheel arm and is then moved to an engagement position where it engages the gauge wheel arm. The location of the engagement position is identified as a calibration point.

  • Actuated seed depth setting for a planter row unit
    Patent number: 10537055
    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 generates a force estimate indicative of a force to make a planting depth adjustment. The control system automatically controls actuation of the seed depth actuator to exert the estimated force.
