Abstract
An actuating cylinder assembly includes a cylinder adapted to contain a fluid, such as hydraulic fluid or air, a piston shaft movable with respect to the cylinder in response to the removal of fluid from the cylinder and the injection of fluid into the cylinder, and a cylinder stop including a handle portion and a clamping portion releasably engaging the piston shaft, the clamping portion resisting movement of the piston shaft with respect to the cylinder past a selected point. The actuating cylinder assembly used, for example, on a riding lawnmower to set a selected minimum cutting height. Once the cylinder stop is set on the piston shaft, the cutting deck may be raised to avoid obstacles and then quickly lowered to the selected cutting height.
