摘要

An agricultural tractor having at least four side-by-side pneumatic rear tires which provide a relatively narrow path of travel, there being a narrow rear portion of the tractor's body having about the same width or less as seen in plan of each of the tires and which is centrally disposed between the tires. A three-point lifting device and towing bar extend rearwardly from the rear body portion and the lower links of the lifting device or bar part extend normally outwardly relative to the body of the tractor in the vicinity of the adjacent central tires to function as a scraper for mud or other material which accumulates on the tires in use. The towing bar which extends rearwardly from the bottom of the rear body portion is rectangular as seen in plan with its sides adjacent to the internal side walls of the two central tires wherein it also acts as a mud scraper, such towing bar being at a level above the ground of about thirty to forty percent of the tire's radius. The towing bar part which extends normally to the tractor body is connected to the towing bar and the tractor's driving seat is located vertically above the axle of the central tires.
