A closed-circuit, fluid-based system propels certain tractors and other equipment manufactured by this prominent agricultural machinery company. This transmission type uses a hydraulic pump driven by the engine to power a hydraulic motor connected to the wheels or other drive components. Varying the pump’s displacement alters the ground speed and direction, offering seamless speed adjustments and infinite variability within the transmission’s range. An example application is in lawn tractors, enabling precise maneuvering and effortless control.
This technology offers several advantages, including simplified operation, eliminating the need for a traditional clutch and gears. The smooth, continuous power delivery improves fuel efficiency and reduces wear and tear on mechanical components. Moreover, it provides dynamic braking, enhancing safety on slopes and challenging terrain. This transmission type has become increasingly prevalent in agricultural and groundskeeping equipment due to its reliability and ease of use, reflecting a significant advancement over earlier mechanical drive systems.
