Abstract
A three wheel cart that is adjustable in both length and width for cargo such as ice chests. The cart provides a pair of rear wheels, a horizontal load platform, and a front drawbar with a third wheel for easy pulling or pushing. The drawbar and third wheel retract under the cart. All adjustments are made without wrenches utilizing a large soft hand nut. The width adjustment is interconnected by a mechanism so that cargo width retainers slide in and out simultaneously along with the cart main wheels. When the drawbar is raised into its towing position the cart's front support leg is levered off the ground by the third wheel. This capability minimizes the lifting effort required when towing the cart. As the drawbar is lowered the support leg becomes an automatic parking brake. The operator cannot abandon the cart without the brake being applied.
