A system includes a tractor comprising a lifting hitch, and an implement comprising an implement frame carried by the lifting hitch. The implement frame has an integrated elongate toolbar carrying at least one row unit. A sensor is configured to sense a position of the at least one row unit relative to the ground. A control system is configured to receive a signal related to the sensed position of the at least one row unit relative to the ground and cause the lifting hitch to raise or lower a portion of the implement frame connected to the lifting hitch relative to the tractor based at least in part on the signal. Control systems and related methods are also disclosed.

Systems comprising agricultural implements connected to lifting hitches and related control systems and methods

An implement includes an implement frame having an integrated elongate toolbar carrying at least one row unit, at least one wheel coupled to the implement frame and defining an axis of rotation, a sensor configured to sense a position of the at least one row unit relative to the ground, and a control system. The control system is configured to receive a signal related to the sensed position of the at least one row unit relative to the ground and cause a lift system to raise or lower a portion of the implement frame connected to the lift system to rotate the implement frame about the axis of rotation of the at least one wheel based at least in part on the signal. Control systems and related methods are also disclosed.
