Patent attributes
A frame control system for an agricultural implement includes a first sensor configured to be coupled to a sub-frame of the agricultural implement and directed toward a soil surface. The first sensor is configured to emit a first output signal toward the soil surface and to receive a first return signal indicative of a first height of the sub-frame above the soil surface. The frame control system also includes a first sub-frame actuator configured to be coupled to the sub-frame and to a main frame of the agricultural implement. The first sub-frame actuator is configured to control a first position of the sub-frame relative to the main frame along a vertical axis. In addition, the frame control system includes a controller configured to control the first sub-frame actuator such that a difference between the first height and a target height is less than a threshold value.
