ABSTRACT:
A tractor has a hydraulically driven PTO shaft disposed at one side and generally centrally so that it can be connected to an input shaft of an implement extending laterally from the tractor's rear lifting device. The tractor's engine is between its wheels and its drive shaft is transverse to the tractor's longitudinal centerline. The width of the engine is less than the width from outboard side to outboard side of the tractor's front wheels. The fuel tank is offset on one side of the tractor opposite the aforesaid PTO. The front wheels of the tractor are situated within the tracks of the rear wheels so that the tracks do not overlap and are about equal distances apart. All wheels are driven by individual hydraulic motors. Hydraulic motors also drive the aforesaid PTO shaft and two further PTO shafts which extend to the tractor's rear, one centered with respect to the tractor's three-point lifting device and the other to one side thereof. An alarm alerts the operator if the power required for the tractor's propulsion is a disproportionate share of that available whereby there is insufficient power for the aforesaid or other PTO shafts and any implements connected thereto. The hydraulic fluid which drives the wheels can be delivered to the front or rear wheels either in series to ensure both wheels are powered or in parallel.
