ABSTRACT:
A transmission for a working vehicle has a power takeout transmission mechanism for connecting an input shaft of a hydraulic stepless speed change device with a power takeout shaft. The power takeout transmission mechanism includes a clutch and a speed change device. A driving transmission mechanism is connected to an output shaft of the hydraulic stepless speed change device and is for driving wheels of the working vehicle. The driving transmission mechanism includes a speed change device and differential gear. The input shaft and output shaft of the hydraulic stepless speed change device are vertically juxtaposed in the front of the transmission. The clutch of the power takeout transmission mechanism and the speed change device of the driving transmission mechanism are vertically juxtaposed in a center of the housing. The speed change device of the power takeout transmission mechanism and the differential gear of the driving transmission mechanism are vertically juxtaposed in a rear of the housing. The clutch is capable of changing the speed change device of the power takeout transmission mechanism without intermittent driving of the vehicle. Accordingly, the clutch and the speed change device of the power takeout transmission mechanism, and the speed change device and differential gear of the driving transmission mechanism are disposed such that a compact transmission applicable to a small-sized vehicle can be provided with low manufacturing costs.
