Golf apparatus for driving ranges and the like. A piston moves upwardly and downwardly in a cylinder below the ground level. Successive golf balls are taken one at a time from a supply of such balls, and raised by the piston either to turf level or to a tee level at an elevation somewhat above the turf level. When the ball is hit by a club, the decrease in weight against a pressure-sensitive switch carried by the piston, serves to close the switch to start an electric motor through the next cycle of operation. An adjustment is provided for determining whether the ball is to be raised only to the turf level, or all the way to the tee level. The adjustment feature of the apparatus also includes a control mechanism which serves to keep the pressure sensitive switch closed and keep the motor operating during the entire cycle of operation, notwithstanding that the weight of the ball during the upward travel from ball loading position to hitting position of the tee would tend to close the switch and stop the motor, if this control mechanism were not provided.
