A variable height-of-cut system for a ground working vehicle including a cutting deck, ground engaging members, and the height-of-cut system. The ground engaging members are rotatably attached to the cutting deck and operable to support the deck relative to a ground surface. The height-of-cut system is adapted to alter a height of the cutting deck relative to the ground surface. The height-of-cut system includes an adjustment plate and a lever. The adjustment plate defines a slot and a plurality of notches extending therefrom. Each notch is adapted to receive the lever and corresponds to a different height of the cutting deck relative to the ground surface when the lever is received therein. The adjustment plate is adapted to move along a longitudinal axis such that the plurality of notches are shifted.
