Abstract
A hydraulic drive device including a center section for rotatably mounting a hydraulic pump and hydraulic motor on respective running surfaces. The center section further includes a pair of ports connecting the running surfaces, where the ports are not located in the same plane but are rather offset from one another with respect to the pump running surface, so that one of the ports is closer to the pump running surface than the other port.
