Ball projecting machine

A ball projecting machine for projecting a ball, comprising:

• a ball projecting head spaced apart from and situated atop a stand, the ball projecting head including a first wheel spaced apart from an opposing surface by a distance roughly equal to a diameter of a ball, and a motor that drives the first wheel;
• a generally C-shaped arm that connects the ball projecting head to the stand, wherein the ball projecting head is affixed to one end of the C-shaped arm, and the C-shaped arm is slidably engaged through a frame atop the stand to allow rotation of the ball projecting head position about a horizontal axis, wherein a center of gravity of the ball projecting head in combination with the C-shaped arm facilitates movement of the ball projecting machine when the C-shaped arm is slid up or down;
• and
• a locking device with a press-fit connection that, when disengaged, allows the C-shaped arm to slide up or down through the frame.
