An agricultural machine has a linkage system for hitching of an implement and an additional axle mounted to the linkage system. The linkage system includes at least one lift arm adjustably mounted to the chassis at an inner end and carrying a fastening device at an outer end. The additional axle is connected to at least one lift arm inboard of the fastening device. The linkage assembly may be a three-point linkage assembly having two lower lift arms, the additional axle being mounted between the lower lift arms.

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.
