Abstract: PROBLEM TO BE SOLVED: To maintain braking state reliably even when a switch for starting an engine is turned off for stopping a combine vehicle on a slope. SOLUTION: In a transmission system for a crawler vehicle, a transmission unit is provided, wherein hydraulic clutches C1, C2 and C3 are interposed in each of a plurality of transmission passages with different transmission ratios. The transmission unit changes a plurality of speeds by selectively causing one of the hydraulic clutches C1, C2 and C3 to operate so as to make one of the transmission passages in a transmittable condition. Further, the hydraulic clutches C1, C2 and C3 are connected to a switch valve 63 for selecting either thereof so as to configure a hydraulic circuit for speed change operation. In addition, the hydraulic circuit for speed change operation is provided with a pressure decrease means for decreasing the pressure of the pressure oil with respect to the hydraulic clutches C1, C2, C3 by turning off a starting switch 68 for an engine 7. Finally, a hydraulic cylinder 69 is connected to the hydraulic circuit for speed change operation so as to operate a parking brake 19 such that it is applied when hydraulic pressure in the hydraulic circuit becomes lower than a prescribed one.

Abstract: PROBLEM TO BE SOLVED: To prevent different left and right stopping motions by an operator's operation of a command means for decreasing hydraulic pressure so as to disengage a hydraulic clutch thus decoupling driving units for right and left crawlers and a transmission system. SOLUTION: A control unit receives an input signal from an exclusive operating switch for selecting a postion between two to stop running, which is mounted at a drivers section. The control unit outputs an actuation signal to a solenoid of a neutral valve 67 based on an on-signal corresponding to the switch-on operation and decreases hydraulic pressure of a hydraulic circuit 66. As a result, a first to third hydraulic clutches C1 to C3 are disengaged and the running is stopped. In this case, the operating switch composes a command means. Further, with the hydraulic pressure decrease in the hydraulic circuit 66, oil is discharged from a hydraulic cylinder 69, too, and a parking brake 19 becomes under braking condition. As a result, a vehicle body is retained stopped in linkage with crawler driving units.
