Do I need to buy anything additional to use all the features of the First Pitch machines?
No, all three machines come with the ball tubes for baseball and softball. The baseline has reversible legs for baseball and softball and the XL has legs that adjust for baseball or softball. The only exception is that the First Pitch Original comes with long legs for baseball or short legs for softball, or you can order it with both for an extra 39.50. Just choose the "Combo" option when adding the item to the cart!
