Abstract
Abstract A golf practice apparatus is provided having a foot-operated winding drum with a line wound thereon, and a golf ball attached to the end of the line. A line guide is positioned for pivotal movement in front of the winding drum for guiding the line onto the winding drum. A foot-operated pedal is provided with a main pedal and an auxiliary pedal, the main pedal being coupled to a gear box for driving the winding drum, and the auxiliary pedal coupled to a lever linkage for driving the line guide. Rocking foot pressure on the main and auxiliary pedals drives the winding drum and the line guide for winding the line with the golf ball attached thereto on the drum. The ball attached to the line may be struck by a club, and the ball will move in the line of flight freely, with the line unwinding from the winding drum. After the ball has come to rest, operation of the main and auxiliary foot pedals automatically retrieves the ball so that the apparatus is then in condition for the next practice shot.
