WORKING VEHICLE, CONTROL DEVICE FOR WORKING VEHICLE, AND CONTROL METHOD FOR WORKING VEHICLE
An object of the present invention is to improve working efficiency of a working vehicle. A working vehicle (1) in which an output from an engine (101) is distributed to a traveling system (103) and a hydraulic device system (104) includes a loading operation detection unit (211) that detects whether a loading operation using a work equipment (51) is being performed, a clutch (110) contained in the traveling system (103) and connected to a distributor (102), a maximum output characteristic control unit (2203) that selects a second engine maximum output characteristic from among first and second maximum output characteristics when it is detected that the loading operation is being performed, and a hydraulic oil amount control unit (212) that decreases a clutch pressure of the clutch (110) when it is detected that the loading operation is being performed. In the first engine maximum output characteristic, a maximum output torque in a predetermined engine revolution speed range is lower than that in the second engine maximum output characteristic.
