Abstract
A transmission for self-propelled walking lawn mowers comprising a casing (23); an input shaft (10) extending within the casing (23); an output shaft (13) penetrating the casing (23) and connected to drive wheels; an intermediate shaft (25) connected to the input shaft (10) via a transmission gear mechanism (24); a plurality of drive gears (26) and a plurality of driven gears (28) mounted on the output shaft (13) to mesh with each other; connecting means for connecting a gear selected from the plurality of driven gears (28) to the output shaft (13); and a clutch (27) mounted on the intermediate shaft (25) to engage or disengage the drive gear set (26) with or from the intermediate shaft (25). According to the present invention, the load imposed on the clutch is effectively reduced, thereby increasing the service life of the obtained product.
