ABSTRACT:
The disclosure relates to a very compact, highly maneuverable, trash collecting and handling vehicle having forward and rearward portions steerably connected together about a vertical pivotal axis located between the front and rear wheels; the front and rear wheels being driven hydraulically through a pair of differentials which are powered by hydraulic motors driven by a pair of respective hydraulic pumps which are variable delivery and reversable wobble plate controlled piston type pumps; and wherein a manual control variably increases flow from said pumps to motors when said manual control is moved in one direction and whereby, when said manual control is moved in an opposite direction, the opposite functions occur with relation to the pumps and hydraulic motors. The disclosure also relates to trash container pickup means and operator control means on the forward portion of the vehicle and a trash receiver carried by the rearward portion of the vehicle. Additionally, the vehicle is provided with a pivotal connection between the front wheels and the rear wheels; such pivotal connection being disposed on a substantially horizontal fore and aft axis so that the axes of the front wheels may be disposed angularly relative to the axes of the rear wheels in order that the vehicle may be efficiently driven over uneven ground while maintaining efficient traction of the wheels thereon.
