Abstract: Disclosed is an apparatus for automatically teeing up golf balls having a hopper, a teeing up device and a control panel. The hopper is operatively connected to the teeing up device to supply golf balls to the automatic teeing up device. The teeing up device comprises a piston moving between a lowermost and an uppermost position within a guide cylinder below the ground level. Golf balls are selected and allowed on a tee one at the time. The tee is adjustable in height to simulate a tee off lie or a fairway lie. A detector is located under the tee to detect the presence of a golf ball on the tee to automatically tee up another golf ball when needed. The control panel activates, controls or deactivates the automatic teeing up device.
