PURPOSE:To improve the drivability of a working vehicle in its road movement, by providing a control circuit for presetting a road movement mode and a working movement mode, and by providing a means for detecting the speed of the movement of the vehicle. CONSTITUTION:An injected fuel quantity control mechanism 12 for a fuel injection pump 11 is operated by an electric actuator 13 electrically connected to accelerator control means 19, 20 through a control circuit 18. A road movement mode and a working movement mode are preset by the controll circuit 18. When an accessory gearshift 32 is put in a high speed position, a governor is controlled in the road nmovement mode. When the gearshift 2 is put in a low speed position, the governor is controlled in the working movement mode. The drivability of a working vehicle in its road movement is thus improved. |
