Abstract
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.
