Abstract
Abstract The drive system comprises an annular member carrying first engagement means which couple to second engagement means carried by drive motor means. The drive motor means are effective to rotate the annular member about an axis of rotation. Specific features of the invention include the use of hydraulic drive motor means operated through the use of a hydraulic system. The drive system also includes a pair of annular members which cooperate with respect to each other in combination with drive motor means disposed adjacent to each of the annular members. A plurality of drive motors may be used in some of the particular combinations and a single drive motor having a central pinion means and a satellite group of gears may also be used in conjunction with the drive motor means.
