Abstract
The present invention is so designed that a housing of a transmission which can drive front wheels and rear wheels and a power take-off shaft is constructed having a first chamber and a second chamber. A hydrostatic transmission is housed in the first chamber. A gear-type speed changing unit is housed in the second chamber. A hydraulic pump and a hydraulic motor are separately disposed on the inner and outer surfaces of the front wall of the first chamber. A clutch mechanism for engaging or disengaging with or from the front wheels for supplying power thereto is also provided. On the housing is provided a restraint mechanism for restraining rearward acceleration more than a predetermined speed by a speed control lever of the hydrostatic transmission when the gear-type speed changing unit is switched to the high speed setting. Left and right running brake units provided on the vehicle are made independently operable by treading left and right turn brake pedals on a first brake pedal shaft and made simultaneously operable by treading a master brake pedal on a second brake pedal shaft.
