The BATA Auto Feeder will work with any BATA machine, as well as many other brands of machines. Please note that this feeder is designed to feed dimpled baseballs and softballs. You may also use leather balls; however, because of the seams, they may feed inconsistently.  Note: This auto feeder is meant for Bata pitching machines only. Other brands are not guaranteed. *Check the baseballs and softballs you are using while feeding. Damaged balls might affect feeding/pitching performance.
