制御装置。 A clutch oil pressure setting valve is connected to the hydraulic oil path between the hydraulic oil pump and the forward/reverse switching valve, and the hydraulic pressure of the reduction/reversing gear is switched freely between the forward and reverse clutches by switching the forward/reverse switching valve. In the control device, a bypass oil passage is provided in the hydraulic oil passage, a clutch fitting pressure setting valve with a low setting pressure is provided in the bypass oil passage, and a pilot oil passage for opening and closing the fitting pressure setting valve is provided through the pilot valve. A pilot valve opening/closing operating oil passage that is connected to the above hydraulic oil passage and has a restriction is connected to the outlet side of the forward/reverse switching valve, and when the forward/reverse switching valve is in the neutral position, the pilot valve opens and the fitting pressure setting valve is activated. Close the hydraulic oil passage and maintain the high hydraulic oil setting pressure using the clutch oil pressure setting valve, and when switching the forward/reverse selector valve to the forward or reverse position, close the pilot valve just before the clutch is inserted while delaying it with the throttle. A hydraulic control device for a reduction/reversing machine, characterized in that a pressure setting valve is opened.
