ABSTRACT:
A garden tractor of the type steered by a walking attendant having a strong central structure in the form of a pair of rectangular plates rigidly interconnected by a centrally located cylindrical member extending transversely therebetween which is conveniently utilized (1) to mount an endless ground-engaging track assembly in a position between the plates so that the endless path of movement thereof encircles the cylindrical member; (2) to support an engine and handle frame assembly thereabove for pivotal movement about the relatively low axis of the cylindrical member; and (3) to mount a rotary motion transmitting shaft concentrically within the cylindrical member which serves to transmit the rotary power from the engine to the endless track assembly while accommodating the aforesaid pivotal movement of the engine and handle frame which carries the cultivator tools.
