Zusammenfassung:PROBLEM TO BE SOLVED: To resolve the problem of lost work efficiency resulting from the impossibility of a quick movement caused by a reduction in an engine revolution speed made in association with the backward movement of a vehicle, because traveling is often carried out at a car speed set low or very low when a plow work machine is connected and work is carried out by turning ON a draft controller, and if the operation of an engine revolution controller is ON during such traveling. SOLUTION: In a tractor equipped with an engine revolution controller for changing the accelerator opening degree of an engine to a reduction side in association with a backward operation or the lifting operation of a work machine, the connected state of a plow work machine is detected based on the connected state of a draft sensor and, when the sensor is connected, or when a setting means 4 for switching ON/OFF the operation of a draft controller is set ON, the operation of the engine revolution controller is checked.
