Abstract
A dual function cart convertible between a wheelbarrow-type load transporter and a vehicle towed cart. The cart comprises a frame supporting a load carrying tube, the frame including a transversing extending axle having relatively large diameter spoked wheels journaled for rotation on opposed ends of the axle. Pivotally secured to the frame is a handle assembly in the form of a rectangular loop which, when latched by a removable rod in a first position orients the handle in an upright plane where the vehicle can be operated as a wheelbarrow. Alternatively, the removable rod may be used to latch the handle in a generally horizontal plane at an elevation facilitating connection thereof by a clevis to a hitch on a towing vehicle. The cart also includes an auxiliary side member which may be secured to the tub for increasing the effective load-carrying volume of the tub.
