## Abstract

A wheel barrow that includes a three-wheel design and a secondary handle so that almost any single user, such as a disabled military veteran, can utilize the wheel barrow compared to traditional wheel barrows. The wheel barrow includes an A-frame, a first front wheel, a second front wheel, a rear wheel, a barrow receptacle, a clevis, and a handle bar. The A-frame is the main structural body of the wheel barrow. The first front wheel and the second front wheel provide a primary conveyance means for the wheel barrow. The rear wheel provides a secondary conveyance means for the wheel barrow and allows the wheel barrow to stand upright without the aid of the user. The barrow receptacle provides a storage means to carry material. The clevis allows the user to change directions when utilizing the wheel barrow. The handle bar provides an efficient leverage means.
