Agricultural implements having row unit position sensors and a rotatable implement frame, and related control systems and methods

A control system for an implement having at least one wheel coupled to an implement frame, the implement frame having an integrated elongate toolbar carrying at least one row unit, the control system comprising:

• a sensor configured to sense a position of the at least one row unit relative to ground;
• and
• a controller configured to receive a signal from the sensor indicating the position of the at least one row unit relative to the ground and cause a lifting system to raise or lower a portion of the implement frame to rotate the implement frame about an axis of rotation of the at least one wheel based on the sensed position of the at least one row unit.

A computer-implemented method for operating a tractor and an implement having a frame coupled to the tractor, the frame supported by at least one wheel and having an integrated elongate toolbar carrying at least one row unit, the method comprising:

• receiving an indication of a position of the at least one row unit relative to ground sensed by a sensor;
• and
• causing a lift system to raise or lower a portion of the implement frame relative to the tractor to rotate the implement frame about an axis of rotation of the at least one wheel based at least in part on the indication of the position of the at least one row unit.
