PROBLEM TO BE SOLVED: To improve the fuel consumption without increasing the amount of fuel injection of an engine more than necessary.SOLUTION: A work machine including an engine, running wheels, an accelerator pedal adjusting the amount of fuel injection of an engine, and a transmission for shifrting the gear and transmitting the power of the engine to the running wheels, includes a controller for chainging the number of revolutions of the engine according to the gearshift position of the transmission, and changing the upper limit value of the number of revolutions of the engine at the maximum pedaling of an accelerator pedal according to the gearshift position of the transmission, prior to its setting. Moreover, the working machine is provided with a gearshift lever switched between the running speed at road rolling and the running speed at planting, and the controller is structured to change the number of revolutions of the engine between the running speed at road rolling and the running speed at planting. |
