PONZA HUMMER REPLACEMENT DISCS

Description

You are looking at the best slow pitch softball pitching machine ever made.  The Ponza Hummer does throw fast pitch baseball and softball but not as accurately as it throws slow pitch.  The reason why the hummer throws slow pitch better and more naturally than any other pitching machine is that it does not use a single wheel with a pad or double wheel format. Hummers use discs to flip the ball. Both of these latter pitching machines throw the ball with an extremely fast and unnatural back spin that an actual pitcher cannot duplicate.  The result is a pitch that moves towards the batter faster than it would when thrown by a human thus ruining your timing.  Pictured here is the Hummer machine that the discs will fit  (white discs are 13", flex/brown disc is 4").  I have used and maintained these machines at my batting ranges for over 35 years.  Included are complete use and installation instructions.  Note that Hummers have not been manufactured for many years now,  but I do have many other parts that I'm willing to sell should the need arise.
