An axle (6) drivingly connected to left and right drive wheels (7) extends through the hollow change shaft. One end of the change shaft is spaced from an inner wall surface of the transmission casing for disposing therebetween an auxiliary clutch (13) which is operable between the change shaft and axle. Both of the main and auxiliary clutches are operated together. The transmission mechanism is provided for a plurality of variable speeds of a mower in a compact fashion owing to a co-axial arrangement of the hollow change shaft and the axle passing therethrough. The auxiliary clutch which is provided also in a compact fashion permits to shift the transmission mechanism lightly and to pull the mower for retreating same with ease.
