Abstract

Abstract A three-wheeled, self-propelled cart characterized in that the operator stands on the cart, straddling a drive motor for two drive wheels while holding onto an upstanding post with one hand and grasping a tongue-type steering pole with the other hand. The steering pole is connected to the third wheel and is curved outwardly and around the aforesaid post such that the operator''s hands will be separated; while movement of the steering pole inwardly or outwardly will cause the third wheel to pivot about a vertical axis to steer the vehicle. A golf bag or other receptacle can be carried on the vehicle ahead of the upstanding post and is usually secured to the post by a strap or the like.
