ABSTRACT:
An articulated agricultural tractor of 100 horsepower or more having front and rear portions connected by an articulation joint, there being only one axle in each portion. The articulation joint is located just inside a vertical plane tangent to the rear treads of the front wheels mounted on the front axle. The engine and its casing are mounted completely forward to the front axle. Each axle carries four wheels with pneumatic tires mounted thereon, all wheels being of the same diameter. The rear portion of the tractor's body is narrow, about the same width or less as seen in plan of each of the tires. The operator's cab and seat are located directly over the rear axle where the operator can see rows just inside all of the front wheels. A three-point lifting device and towing bar extend rearwardly from the rear portion with the lower links of the lifting device or bar part extending normally outwardly relative to the body of the tractor in the vicinity of adjacent central tires. The distance between the front and rear tires is about one-half the diameter of each tire. A ladder for the operator to climb into the operator' s cab is affixed to the cab between the wheels as seen in side elevation. Fuel tanks are mounted on each side of the housing for the engine forward of the front wheels, each fuel tank being triangular as seen from above. The lower parts of the differential for the first axle and the engine are at substantially the same level.
