Abstract
Abstract A golf cart or other personal utility vehicle includes a wheeled platform, a wheeled gooseneck frame detachably secured at the rear of the platform, and a detachable steering handle for turning a powered wheel on the gooseneck frame for steering purposes. A detachable upright post provides support for a conventional golf bag and set of clubs. A forwardly facing occupant seat is detachably mounted to the gooseneck frame, thereby placing the weight of an occupant substantially upon the rear driving and steering wheel. The golf cart provides a mechanized vehicle capable of use on all types of terrain. It can be readily disassembled for storage and transport within the trunk or cargo area of a conventional passenger automobile.
