ABSTRACT:
A tractor with two engines arranged in tandem, each carried by a frame portion pivotable relative to the other about a vertical axis under the rear engine. The body of the tractor is narrow forward and to the rear wherein axles for front and rear sets of ground engaging wheels extend laterally and mount six wheels each. The front engine and rear engine extend forward of the respective front and rear sets of ground wheels. The front frame portion is turnable axially relative to the rear frame portion and steering is accomplished by the relative pivoting of the portions about the aforesaid vertical axis. A fuel tank forms a guard over the rear set of wheels and includes a depression for an operator's seat. The fuel tank has a central partition and is optionally hinged in its outer portions whereby the width of the tractor is reduced by removing the outer wheels and pivoting the outer portions of the fuel tank to the rear. A lifting device extends aft between the central rear wheels.
