ABSTRACT:
A golf ball driving device is disclosed, being a device which is mounted on wheels for easy maneuverability, and having generally an operating and transport handle, and a trigger release handle. The operating handle has a cam and ratchet at its lower end, for driving a ratchet bar against a compression spring (or pneumatic cylinder) to create compression force. The trigger release handle has a follower arm which latches against the ratchet bar, and it is moveable to release the ratchet bar and thereby to release the compression force. A striker plate moves forwardly and downwardly upon release of the compression, to strike a golf ball when in place. The striker plate is rotatably adjustable so that its angle and point of impact against a golf ball may be adjusted.
