A portable livestock apparatus has a frame, removable transport wheels situated on a wheel axis located intermediately between opposing front and rear ends of the frame, and a front lifting jack mechanism disposed forwardly of the wheel axis. Transition of the apparatus between a ground-seated field-use position and a wheel-carried transport position is performed using only the front lifting jack mechanism, without requiring a separate rear lifting jack mechanism behind the wheel axis to enable installation and removal of the transport wheels. Full extension of the front lifting jack mechanism raises the front end far enough to provide sufficient ground clearance at the wheel axis for installation and removal of the transport wheels. A singular lift-lower operation by the singular jack thus enables both hitch connection/disconnection and wheel installation/removal.
