ABSTRACT:
A tricycle frame is elongated to carry a sprayer or a fertilizer spreader, or the like. Two transversely spaced rear wheels engage the ground at the rear of the frame and are independently driven by hydraulic motors. A ground engaging front wheel, also independently driven by a hydraulic motor, steers the vehicle. The front wheel is carried on a steering post including a vertical spindle journaled on a framework extending forwardly from the main frame. A cantilever mounted on the steering post projects forwardly beyond the steering wheel and downwardly. On its forward end the cantilever supportsa cab housing the operator and the controls of the vehicle. The cantilever construction not only enables the cab to achieve a low profile but allows the cab to swing laterally well in excess of the movement of the steering wheel, thereby affording a clear rear view to the operator in the cab whenever required.
