ABSTRACT:
A tractor of width acceptable for highway travel having a narrow rear body portion between the rear wheels, the width of the body portion being less than the width of each pneumatic tire mounted on the rear wheels. Four or six rear tires which are rotatable on the same axis have the narrow body portion disposed centrally and closely between them, such body portion extending forwardly relatively to the rear wheels with the forward portion of the body, which is substantially wider than the rear portion, mounting an engine near the front wheels. A power transmitting linkage connects the engine with the rear wheels through the rear body portion which, with lateral projections, houses a differential and the necessary shaft bearings. A lifting device extends rearwardly from the rear body portion to behind the rear wheels and then extends laterally where it functions to scrape mud or the like from the treads of the rear tires. A tow bar also extends aft from the rear body portion which is sufficiently wide to scrape mud or the like from the interior sides of the closest rear wheels.
