ABSTRACT:
A belt-driven transmission designed particularly for self-propelled, walking lawn mowers is provided. The transmission is mounted on a deck of a mower between a front pair or a rear pair of wheels and is driven through a pulley on the engine drive shaft and a pulley on the transmission connected by a belt. With this arrangement, the engine requires no special power take-off shaft to drive the mower. Consequently, the transmission can be universally applied to many different self-propelled lawn mowers. The new transmission can also be equipped with a deadman's clutch. Further, it can be provided with a manually-adjustable pulley of variable diameter to provide different speeds and torque for the drive shaft of the driven wheels. Also, in accordance with the invention, the drive shaft has a ratchet coupling device near each driven wheel to provide a differential effect for the wheels when the mower is being turned.
