Abstract
A hydraulic fluid cooling system for a pair of integrated hydrostatic transmissions includes a common reservoir holding hydraulic fluid and having hydraulic lines connecting the common reservoir to each integrated hydrostatic transmission, a hydraulic fluid reservoir inside each integrated hydrostatic transmission, and a pump for pumping fluid from each transmission's hydraulic fluid reservoir to the other transmission. An auxiliary hydraulic circuit is between the pair of integrated hydrostatic transmissions. The system pumps hydraulic fluid from one of the integrated hydrostatic transmission to the auxiliary hydraulic circuit, and the return line from the auxiliary hydraulic circuit may be connected to the other integrated hydrostatic transmission.
