Abstract: An automatic golf ball teeing up device for use by a golfer at driving ranges, and other facilities. The teeing up device includes a pair of holding cylinders, a pneumatic cylinder, and a photoelectric sensor in communication with a timer and relay. A holding cage and tube gravity feed golf balls one at a time past the holding cylinders into a loading chamber. The pneumatic cylinder has a piston rod having a tee thereon, which extends upwardly through the loading chamber to tee up the golf ball. The photoelectric sensor has a photoelectric eye and reflector axially aligned with the teed up golf ball therebetween. When the golf ball is removed from the tee, the photoelectric eye and reflector connect to signal the timer and relay to actuate the holding cylinders and pneumatic cylinder to feed and tee another golf ball.
