All quality tennis ball machines presently available on the market use wheels to throw the ball. Normally there are two wheels that turn in opposite direction (thus the label counter rotating wheels) and have a small space between them. The ball rolls down a chute and are squeezed by the counter rotating wheels, which then eject it. The situation is not all that different from gravel being thrown from under a spinning tire, though in the case of the tire only one wheel is responsible for the throwing.

Two types of testing machine are commonly used for evaluating the fatigue characteristics of balls and rollers. One, in which the upper ball, held in a driven chuck, causes three lower balls to rotate in a race, is often referred to as a four-ball machine. The other type consists of a roller or disc loaded between two rollers or cylinders of larger diameter, one of which is driven by an electric motor. A device, sensitive to vibration, is attached to both types of machine, which stops the machine automatically when pitching occurred.

Remote unit starts and stops the ball throws, and also starts and stops the oscillator to position ball throws anywhere across the court.
