发明名称 WORKING VEHICLE
摘要 PROBLEM TO BE SOLVED: To provide a working vehicle which can prevent unstable turning caused by allowing a braking force of a running portion to give effect to a drive force of the running portion inside the turning, and can prevent advancing of a running machine body to a direction unexpected by an operator.SOLUTION: A working vehicle includes: right and left side clutches that allow each of the driving forces to right and left running portions to be intermitted while operating the right and left running portions by an engine; a side clutch operating tool 14 that intermittently operates each of the right and left side clutches; and a drive force reducing means 84 that transmits the drive force smaller than the drive force generated when the side clutches are continued to be in operation. In the working vehicle, the running portion inside the turning where the side clutches are disconnected is configured to be driven by the drive force smaller than that of the running portion outside the turning where the side clutches are not disconnected in such a state that both parking brake for simultaneously braking the right and left running portions while the side clutches are continued to be in operation and side brake that separately brakes the right and left running portions while the side clutches are disconnected, are not in braking operation.
