Abstract

The wheelbarrow of the present embodiments provides a frame and a tub wherein the tub has a recess for receiving at least a portion of a wheel. Additionally, at least a portion of the frame and a portion of the tub may extend forward of the wheel. Further, a distance between a center of gravity of the tub and a vertical line or plane bisecting a rotational axis of the wheel when the wheelbarrow is in a resting position may be approximately equal to or less than a radius of the wheel. Also, the wheelbarrow may be powered by an engine or motor. The wheelbarrow may also include a transmission capable of rotating the wheel in a forward or reverse direction. Moreover, the wheelbarrow may contain control levers located adjacent handle grips for controlling the motor or engine, or the transmission.
