Abstract: A work vehicle includes front and rear wheels, a transmission case and a power transmission device. The power transmission device is housed in the transmission case and is configured to transmit driving power from an engine to driving wheels. The power transmission device has a front wheel driving shaft and a four-wheel drive clutch. The front wheel driving shaft is arranged in a lower inside portion of the transmission case and is configured to transmit the driving power to the front wheels. The four-wheel drive clutch is arranged above the front wheel driving shaft, and is configured to switch between a two-wheel drive state in which the driving power is transmitted to the rear wheels, and a four-wheel drive state in which the driving power is transmitted to both the front wheels and the rear wheels via the front wheel driving shaft.

Abstract: In a work vehicle, because of growing need to equip a DPF for exhaust gas countermeasures near an engine and a request of increasing the size of a fuel tank, a system including the fuel tanks provided below a floor step and on left and right sides of a transmission case has been employed. However, when a lawn mower is installed between front wheels and rear wheels, an increasing width of a vehicle body becomes a problem.To solve the problem, a locus of the raising and lowering operation of a lawn mower 5 is specified by a parallel link formed of left and right front links 43, 43 and left and right mid links 45, 45, and in a work vehicle where the lawn mower 5 is freely raised and lowered, the left and right mid links 45, 45 are respectively disposed between a transmission case 3 and fuel tanks 16L, 16L.
