Mounting frame for use with a kit for converting conventional pitching machine into a video pitching machine

The present invention comprises a unique mounting frame for use in conjunction with a conversion kit for a conventional, combination baseball/softball pitching machine of the wheel type. Both machines are separately mounted on individual base plates that are pivotably mounted to the front of the frame. The plates are interconnected so as to move in an integral manner pivoting relative to the front of the frame. Movement is controlled by a linear actuator which permits them to be raised and lowered as a single unit by a single raise and lower mechanism.
