A lawnmower comprising a chassis and a mower deck movable with respect to the chassis. A cylinder assembly is mounted to the chassis, and includes an actuating cylinder, and a piston shaft selectively extendable and retractable with respect to the cylinder under the influence of fluid pressure within the cylinder. A deck lift assembly is interconnected to the chassis and the mower deck for adjusting the height of the mower deck with respect to the chassis. The deck lift assembly includes a pivot member pivotally connected to the chassis. A jack is removably coupled to the pivot member, such that the chassis is raised and lowered in response to movement of the piston shaft with respect to the cylinder. The jack utilizes the existing hydraulic system and cylinder assembly of the lawnmower to raise the lawnmower with respect to the ground.

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.
