US Patent 7716906 Single lever mower deck height-of-cut control

A single lever mower deck height-of-cut control provides a hand control connected to a depth stop cam that is movable to a plurality of cutting height positions. A push button switch on the hand control may be actuated to extend a hydraulic lift mechanism against a lift arm to raise the mower deck. The mower deck descends while the push button switch is not actuated until the lift arm engages the depth stop cam at a specified cutting height position.
