A ball pitching and throwing apparatus that is readily adaptable to propelling a variety of balls, including softballs and baseballs. The apparatus provides a self-contained portable power source, portability and ease of maintenance. The ball pitching apparatus, which includes a portable body, has a stand alone power source that is engaged to a propelling wheel by way of an axle. A ball is loaded into a feeder chute which directs the ball toward a space between the outer periphery of the propelling wheel and an, optionally adjustable, propulsion alignment. Upon contact with the both the outer periphery of the propelling wheel and the propulsion alignment, the ball is propelled from the apparatus. The initial trajectory of the ball can be changed by altering the disposition of an axle mounted pivot arm upon which is mounted the propulsion alignment. A clutch mounted on the body includes an idler wheel and reciprocatingly engages and disengages the engine from the axle upon which the propelling wheel is mounted. The revolutions per minute of the wheel can be varied.
