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).
