Abstract
A powered wheel assembly for use in connection with a wheelbarrow includes in one embodiment a frame that includes support members, a wheel assembly that includes a wheel, an axle, and axle housing, and a pin for connecting the axle and axle housing, and a drive assembly that includes a primary gear drive and a final chain drive. Upon retrofit to an existing wheelbarrow, the powered wheel assembly permits an operator to selectively operate the wheelbarrow in a powered and non-powered mode of transport.
