Abstract
A lawn mower has drive wheels which are independently spring-suspended from the chassis. In one embodiment two rear wheels are independently driven for directional control, two front wheels are mounted at opposing ends of a center pivoting front axle, and the cutter deck is suspended between the front and rear wheels. In another embodiment the front wheels are drive wheels, the rear wheels are steerable, and the cutter deck is cantilevered from the front of the chassis. Wheel assemblies are attached to the chassis by a suspension system comprised of upper and lower link assemblies and a coil spring, preferably one in which the link assemblies are parallel and of equal length.
