Abstract: A power lawn mower has a drive which includes a pair of pulleys affixed to a shaft which is rotatably supported on a pair of arms which are each mounted at one end for pivotal movement about the axis of the engine power takeoff shaft. The arms are also supported intermediate their ends by rods which are pivotally supported at the lower ends on the rear wheel axles. A belt and a pair of pulleys couple the power takeoff shaft to the pulley shaft. A second pair of belts and pulleys couple the pulley shaft to pulleys affixed to each of the rear wheels.
