Abstract: A tractor including: a traveling body having an engine; a post-processing device configured to purify exhaust gas of the engine; and a reductant tank configured to store a reductant to be supplied to the post-processing device. A pair of left and right fuel tanks are arranged respectively on left and right sides of a longitudinally midway portion of the traveling body. A tank-accommodation recess for accommodating a reductant tank is formed at a lower-front portion of one of the left and right fuel tanks. While the reductant tank is accommodated in the tank-accommodation recess, an upper front portion of the fuel tank and the reductant tank are aligned up and down.
