式変速装置。 A forward/reverse gear transmission H 2 equipped with a hydraulic cylinder 11 for operating a transmission shifter, a speed setting gear transmission H 1 , H 3 equipped with hydraulic cylinders 10 and 12 for operating a transmission shifter, and a hydraulically operated friction transmission clutch. C are provided in series in the travel transmission system, and the hydraulic cylinders 10, 11,
12, and pilot pressure operated clutch control valves T1 , T2 for the hydraulic cylinder 13 for operating the clutch C.
, T3 are respectively provided, and the hydraulic cylinder 11 for forward/reverse transmission is operated by using the pressure oil from the transmission control valve V2 as pressure oil for clutch manual operation only in the operating state for the transmission side. T 1 , T 2 ,
In addition , the hydraulic cylinders 10 and 12 for speed setting are configured so that the pressure oil from the speed change control valve V1 is used to control the clutch only when the speed setting hydraulic cylinders 10 and 12 are operated on the transmission side. Valve T 1 , T
2 and T3 are used as switching valves S2 , S3 , and S4 for supplying pilot pressure to switch the clutch engaged state, the hydraulic cylinder 11 for forward/reverse shifting and the clutch between the clutch control valves T 1 , T 2 , T 3 and the clutch operation hydraulic cylinder 13 , and between the speed setting hydraulic cylinder 10 , A pressure sensor (
A hydraulically operated transmission device in which sensors U to U 5 are provided, and alarm devices (P 1 to P 5 ) are separately provided based on the oil sand drop detection results of the respective sensors (U 1 to U 5 ).
