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.
A tractor comprising an engine and front and rear ground wheels, the ground wheels including pneumatic tires, a lifting device being provided in the central region of the tractor between said rear ground wheels which includes a pair of links that each extend outwardly from said central region of the tractor to intercept planes which contain the side surfaces of said tires that are closest to said lifting device and extend in opposite directions laterally outwardly to sufficiently proximate the treads of said closest tires whereby they comprise effective scraper means to remove mud and the like from said closest tires, said planes being substantially parallel to the intended direction of forward travel of the tractor, said links each being an integral unitary continuously rigid structure and being provided at their respective outward ends with rearwardly extending coupling means for the attachment of implements, a platform being provided on which a driving seat is arranged, said driving seat for an operator seated thereon facing forward being located substantially above the axle of at least two of said rear ground wheels which are driven and at a level higher than said two rear ground wheels, upright pivot means supporting said seat above said platform whereby said seat is turnable so an operator can selectively face forwardly and rearwardly.
A tractor comprising:
