A working vehicle with an HST in which over-rotation of a hydraulic pump in the HST or the pump input shaft thereof is prevented when a main clutch is disconnected during a run. When a main clutch connection/disconnection detection means (112) detects (S2) the disconnection state of the main clutch (22) during a run, a control means (110) judges (S3) whether a vehicle speed detected by a vehicle speed detection means (116) is at least a set speed or not, and if the vehicle speed is at least the set speed, the movable swash plate (55) of the hydraulic pump (51) in an HST (50) is controlled to sustain it at the current inclination angle (S4).
