Abstract
An improved lawn mower includes a chassis assembly having one or more drive wheels, a ground-following cutter deck assembly attached to the chassis, and rolling mechanism attached to the cutter deck, wherein the chassis and the cutter deck are arranged such that the rolling mechanism and the drive wheels support the chassis for movement over a surface. The ground-following cutter deck thereby reacts to the ground contours independent of the reactions of the chassis, and the combined weight of the chassis and cutter deck keep the cutter deck from bouncing, thus, the ground-following cutter deck follows the ground contours evenly.
