Abstract: A multi-wheeled, self-propelled device that alters an existing walk behind caddy in that the operator stands on a motorized platform while holding onto an assembly which is attached to the handlebar of said walk behind golf caddy. The self-propelled device is temporarily attached to the bottom portion of the walk behind golf caddy. The power supply and motor remain part of the platform and the control (throttle/brake) remains part of the attached handlebar assembly.
