Abstract: A tractor includes: a three-point linkage to which a tiller is mountable a hydraulic lifting/lowering driver to lift and lower the three-point linkage, and a mechanical linkage to transmit a lifting/lowering operation amount of the three-point linkage to the lifting/lowering driver. The mechanical linkage includes a load detector to detect an amount of change in traction load via the three-point linkage, a cable to interlock according to the amount of change in the traction load detected by the load detector, and a mechanical linkage interlocked and connected to the cable and the lifting/lowering driver, the mechanical linkage being capable of transmitting the lifting/lowering operation amount according to the amount of change in the traction load to the lifting/lowering driver.

Abstract: A floor arrangement of a driver's section of a vehicle includes a floor frame, an acoustic absorbent placed on the floor frame and a floor mat placed on the acoustic absorbent. A wire harness is placed in an acoustic absorbent-free space formed between the floor frame and the floor mat. A protector is provided inside the acoustic absorbent-free space in the vicinity of the wire harness and extends upward from the floor frame. This protector is affixed to the floor frame and configured to receive a load applied to the floor harness from the upper side thereof.

Abstract: An improvement in a work vehicle having an exhaust gas treatment unit is disclosed. An engine is disposed in an engine room formed in a vehicle body and supported by the vehicle body. A support unit includes right and left vertical struts mounted on the vehicle body across the engine along a vehicle body transverse direction. The exhaust gas treatment unit is disposed inside the engine room and attached to the support unit upwardly of the engine, under a posture elongate along the vehicle body transverse direction.

Abstract: A tractor with a cab disposed rearwardly of a hood, the cab being mounted on a tractor body (T) including a body forming unit, the cab including a bottom wall defining left and right footrests. The cab has a total length larger than a total height thereof. The cab is arranged to have the footrests substantially level with a lower end of the body forming unit. The cab has an intermediate height level (x) lower than a height level of the hood.

Abstract: A tractor with a cab (C) disposed rearwardly of a hood (8), the cab being mounted on a tractor body (T) including a body forming unit (100; 3, 4, 5, 6), the cab including a bottom wall (27) defining left and right footrests (27a, 27a). The cab (C) has a total length (L) larger than a total height (H3) thereof. The cab (C) is arranged to have the footrests (27a, 27a) substantially level with a lower end of the body forming unit (100; 3, 4, 5, 6). The cab (C) has an intermediate height level (x) lower than a height level (H4) of the hood (8).
