A hydraulic fluid cooling system for a pair of integrated hydrostatic transmissions (101, 102, 202, 204), includes a common reservoir (103, 222) holding hydraulic fluid and having hydraulic lines connecting the common reservoir to each integrated hydrostatic transmission (101, 102, 202, 204), a hydraulic fluid reservoir inside each integrated hydrostatic transmission (101, 102, 202, 204), and a pump (132, 133) for pumping fluid from each transmission's hydraulic fluid reservoir (101, 102, 202, 204), to the other transmission (101, 102, 202, 204). An auxiliary hydraulic circuit (200) is between the pair of integrated hydrostatic transmissions (101, 102, 202, 204). The system pumps hydraulic fluid from one of the integrated hydrostatic transmission (101, 102, 202, 204), to the auxiliary hydraulic circuit (101, 102, 202, 204), and the return line from the auxiliary hydraulic circuit (200) may be connected to the other integrated hydrostatic transmission (101, 102, 202, 204). |
