In the present invention, an instruction output unit (33) of a tractor (1) outputs a work instruction for controlling a work machine (3) to a working state and a non-work instruction for controlling the work machine (3) to a non-working state. A work margin distance storage unit (54) sets a target switching position at which a work machine control unit (34) performs control to switch the work state of the work machine (3). A vehicle speed control unit (35) switches the speed of the tractor (1) from a speed in the working state to a speed in the non-working state in response to the non-work instruction, and switches the speed from the speed in the non-working state to the speed in the working state in response to the work instruction. A remaining distance acquisition unit (37) acquires the remaining distance from the work center of the work machine (3) to the target switching position. The instruction output unit (33) controls the timing of output of the non-work instruction on the basis of the speed in the working state and the remaining distance. The instruction output unit (33) also controls the timing of output of the work instruction on the basis of the speed in the non-working state, the speed change rate from the speed in the non-working state to the speed in the working state, and the remaining distance.
