Abstract: A device for step-feeding golf balls one at a time over a tee located beneath a ground play surface, and for reciprocating the tee (and associated golf ball) vertically through an aperture made in the ground play surface. The striking height of the tee is adjustable with a control lever. At the selected upper limit position of the tee, the ball can be struck by a golf club, whereby the resilient tee will swing laterally under the impact blow before returning to its initial upright position. The ground surface edge surrounding the tee passage aperture carries a downturned arcuate lip, defining a generally funnel shape configuration. Hence, during lateral sway of the resilient tee after club impact, the tee body will smoothly conform to the arcuate shape of the lip, without contacting the platform bore edge, before returning to its original upright orientation. This in effect substantially reduces the occurrence of shearing damage about the rubber tee.
