PROBLEM TO BE SOLVED: To prevent an engine load from becoming excessively high with respect to an engine output revolving speed at a time of executing a deceleration control in a tractor executing the deceleration control using a lower revolving speed than a set revolving speed by an engine-revolving-speed change operation member as a target revolving speed of an engine-revolving-speed change actuator in place of a normal control using the set revolving speed as the target revolving speed of the engine-revolving-speed change actuator if an operating machine is located at a non-operating position.SOLUTION: A control unit can execute a torque control in addition to the normal control and the deceleration control. The torque control is started if an engine load exceeds a predetermined value at a time of executing the deceleration control, and a corrected revolving speed higher than the low revolving speed is used as the target revolving speed. |
