An important note re pitching machines and real balls:
Most real ball pitching machines require real leather baseballs. Synthetic covered baseballs cannot hold up nearly as well to the stress of a pitching machine, resulting in stripped covers and damaged machines.
In addition, you get a 5 gallon bucket with padded lid.
