Tillage apparatuses and related methods

An apparatus comprising:

• a frame;
• a front wheel assembly mounted to the frame, the front wheel assembly having a front wheel and a front leg support assembly, the front leg support assembly operable to provide variable height positioning of the front wheel relative to the frame;
• a rear wheel assembly mounted to the frame, the rear wheel assembly having a rear wheel and a rear leg support assembly, the rear leg support assembly operable to provide variable height positioning of the rear wheel relative to the frame;
• a drive device connected to both the rear wheel assembly and the frame, the drive device operable to adjust and hold the height between the rear wheel and the frame;
• and
• a force transfer mechanism operable to translate a generally vertical force applied to the rear wheel assembly by the drive device into a torque acting on the front wheel assembly such that the front wheel leg support assembly pivots relative to the frame about a forward portion of the frame to adjust a height between the front wheel and the frame.

• a drive device connected to both the rear wheel assembly and the frame, the drive device operable to adjust and hold the height between the rear wheel and the frame;
• a mechanical linkage mechanism operable to translate movement of the rear wheel relative to a rearward portion of the frame to movement of the front wheel relative to a forward portion of the frame;
• and
• an offset drive device operable to adjust a position of the front wheel assembly relative to a coupling between the mechanical linkage mechanism and the front wheel assembly.
