ング機構。 Skid steering is applied to a transmission equipped with a hydraulic clutch type transmission using a hydraulic pump P1 as a hydraulic power source, hydraulic steering clutch devices 8L and 8R, and hydraulic steering brake devices 9L and 9R using a hydraulic pump P2 as a hydraulic source. In a configuration in which a skid steering valve 40, a skidded hydraulic clutch device 5, and a bevel gear device are attached to enable skid steering, pressure oil from the hydraulic pump P1 side is introduced to the cutting-side cylinder 8a of the hydraulic steering clutch device 8L, 8R. Position steering levers 55L and 55R that communicate with the oil passage.
Pressure oil switching valves 16L and 16R are provided, which are equipped with pressure oil switching valves 16L and 16R that switch to block the hydraulic pump P1 side just before the end of the operation, and instead guide the pressure oil from the hydraulic pump P2 side. A skid steering mechanism characterized in that a skid hydraulic clutch device 5 is connected via the skid steering valve 40 in the middle of the oil path leading to the cutting side cylinder 8a on the secondary side of the switching valves 16L and 16R.
