PROBLEM TO BE SOLVED: To secure a high rotating speed sufficient to supply operating oil required to operate a working device, as the rotating speed of a hydraulic pump, without application of an excessive load on an engine.SOLUTION: The working vehicle includes: a target rotating speed arithmetic unit 38 which determines a target rotating speed of the engine 5 according to the operation of an accelerator operation unit 37; an increase rotating speed setting unit 40 capable of setting an increase rotating speed with respect to an engine rotating speed; an engine rotating speed control unit 46 which controls the engine rotating speed; and a manually operational command unit 44 which gives an increase command of engine rotating speed. The engine rotating speed control unit 46 performs accelerator control, when no increase command is given by the increase command unit 44, to adjust the engine rotating speed to the target rotating speed, and performs increase control, when the increase command is given by the increase command unit 44, to adjust the engine rotating speed to the high rotating speed-side rotating speed of the target rotating speed and the increase rotating speed. |
