    摘要: A working vehicle has improved operability and working efficiency during loading. A loading operation detector detects the start of a loading operation based on at least two of the following: whether a boom lever has been operated in its raise direction; whether a boom is in an attitude set in advance; whether the boom angle is less than an upper limit; whether a speed ratio when a brake is OFF is greater than or equal to a predetermined value; whether a predetermined speed stage is set; whether the traveling range has been changed from reverse to forward; and whether the angular velocity of the boom is greater than or equal to a predetermined value. By increasing the discharge amount of a loader pump, and/or by supplying hydraulic fluid to a boom cylinder from a switch pump, a hydraulic fluid amount increase controller supplies more hydraulic fluid to the boom.
