Abstract: A golf ball striking device has a framework with a club and shaft assembly rotatably mounted to the framework for movement along a swing path in a first vertical plane. A golf ball tee assembly is also rotatably mounted to the framework for free movement in a second vertical plane into any one of a plurality of positions, and structure is provided for releasability locking the golf ball tee assembly in place at the selected position. A golf ball tee is located at the outer end of the golf ball tee assembly for holding a golf ball in the first vertical plane in the swing path of the club and shaft assembly. A structural arrangement on the golf ball tee assembly maintains the tee vertical at any of the plurality of positions of the golf ball tee assembly. A motivator is connected to move the club and shaft assembly along its swing path for striking a golf ball on the tee.
