ABSTRACT:
A working vehicle, for example, a lawn mower, floor brush, or snowblower, is disclosed wherein a steerable ground-engaging wheel is located within the sweep of a rotary mechanism. A spindle portion of the wheel is journaled in a sleeve portion of the rotating mechanism and the mechanism is operatively connected to a power source by a power transfer system. The wheel and the rotary mechanism are independently rotatable. Apparatus is provided in both the single cutter and multiple cutter embodiments to adjust the height of the rotary mechanism as a unit. An alternate drive mechanism is disclosed for use with such devices in which a ground-engaging wheel interior of the rotating mechanism is individually powered. In another embodiment, the wheel is castered. Each of the rotating mechanisms includes a rotatable member rotatably supported within a receiving portion of a body which includes a plurality of support wheels. One of the supporting wheels includes a spindle rotatably journaled within and adjacent to the rotatable member. Cutting blades, brushes, or snow blowing attachments may be secured to the rotatable member.
