A transmission for self-propelled walking lawn mowers, comprising: a casing 17; an input shaft 5 vertically inserted into the casing 17; an output shaft 10 extending horizontally through the casing 17; a small gear 20 fixed on the input shaft 5; a large gear 21 meshing with the small gear; a supporting shaft fixedly spporting the large gear; and first and second intermediate gears 24 and 25 mounted on the supporting shaft and the output shaft 10, respectively, wherein the input shaft 5 is arranged on the side of the. large gear facing opposite to the supporting shaft and is supported by the top and bottom walls of the casing.
