Abstract: A rockshaft is mounted over the front rank of the implement frame and is operated by cylinders located at opposite ends of the rockshaft connected to lift arms extending radially adjacent bearing mounts. Fore-and-aft extending links aligned with the lift arms and mounts operate lift wheel assemblies. A hitch arm connected near the center of the rockshaft is directly connected to a hitch turnbuckle for level lift operation. An aligned arrangement of cylinders, cylinder brackets, links and arms provides minimal torsional loading, particularly when the rockshaft is rotated to fully raise the implement frame for transport and is in the most susceptible shock loading condition. Moment arms are controlled to minimize rockshaft torsional loading during highest stress conditions. The front-mounted rockshaft provides simplicity and advantageous weight distribution.

Abstract: In an electric or hybrid electric vehicle, a voltage monitor (102) is directly coupled to a traction motor (38) and/or generator motor (30) to detect a permanent magnet induced voltage within the motor at a predetermined speed and no load condition (300).
