摘要： A two-axle, four-wheel tractor in which the tractor body composed of a transmission case is offset to one side, with a steering assembly disposed on one side of the tractor body. The tractor body, transmission unit, brake assembly and hydraulic unit for working implements for a tractor of the non-offset standard type are usable for the offset tractor. A pair of long and short rear axle cases covering a pair of rear wheel drive shafts of similarly varying lengths respectively extend outward from the tractor body provided with brakes on its opposite side walls. The rear axle cases are provided on their outer ends with downwardly extending cases each housing a reduction gear for driving the corresponding rear wheel. The tractor body has a large body-to-ground clearance with the front axle also positioned at a high level. The tractor body has on its top a hydraulic unit and at its rear portion a working implement connecting assembly extending rearward as offset from the body and the hydraulic unit in a direction opposite to the direction of offset of the body so as to render the working implement operable with stability and smoothly despite the offset arrangement of the tractor body.
