MF124 Series Variable Speed Hydraulic Gear Motor for Wheeled Tractors

MF124 Series Variable Speed Hydraulic Gear Motor For Wheeled Tractors

Infuse intelligent power into modern wheeled tractors! The MF124 Series Variable Speed Hydraulic Gear Motor is specially designed for the variable speed drive requirements of agricultural machinery, integrating reliability and precise control. This advanced variable speed hydraulic motor adopts a high-performance gear structure and achieves precise control of output speed through stepless regulation of hydraulic flow - seamlessly adapting from smooth drive during low-speed sowing to efficient operation during high-speed transfer. As the core product of the mf124 series, the mf124 motor is an ideal choice for driving tractors, Ptos (Power output shafts), or various agricultural machinery such as seeders and harvesters. It can significantly enhance operational flexibility and fuel efficiency, providing stable power support for precision agriculture operations. ​

The innovative variable speed hydraulic motor design achieves continuous stepless variation of the output shaft rotational speed (from 0 to the maximum speed) by adjusting the system flow rate. Without relying on mechanical gearboxes, it can precisely match the speed requirements of different operations such as sowing (low speed), fertilizing (medium speed), and harvesting (variable speed). This not only simplifies the transmission structure of the tractor but also avoids the power interruption caused by mechanical gear shifting, making the operation process smoother. For instance, during sowing operations, the rotational speed can be stabilized at 30-50 RPM by fine-tuning the flow rate to ensure uniform sowing depth. When changing locations, it can quickly increase to over 200rpm, improving the movement efficiency. ​

The mf124 motor adopts a reinforced gear pair and an optimized housing design. The gear tooth surfaces are hardened (with a hardness of up to HRC 58), and the housing is made of high-strength cast iron. This enables it to offer high starting torque (starting torque coefficient ≥0.9) and continuous stable power output, easily handling challenges such as heavy-load starts (like carrying a heavy-duty seeder to start), slope operations (such as mountain terraced field cultivation), and driving of agricultural machinery (such as the cutting mechanism of a combine harvester), avoiding operation interruptions caused by insufficient torque. ​

The mf124 series motor significantly enhances mechanical efficiency (≥90%) and volumetric efficiency (≥88%) by optimizing the internal flow channel design and adopting low-friction bearings. When operating at low speeds, it can reduce the energy loss caused by the backflow of hydraulic oil. When operating at high speed, it reduces mechanical friction losses, thereby alleviating the load on the tractor's hydraulic system. In practical applications, tractors equipped with the mf124 series motor can reduce fuel consumption by 8-12%, making them particularly suitable for long-term field operations. ​

The mf124 motor is specially designed for agricultural environments: Its compact structure saves installation space and can be flexibly adapted to different models of wheeled tractors. The shell adopts an impact-resistant design and can withstand the vibration and shock caused by the jolts in the field. The sealing system reaches an IP67 protection level, featuring excellent dust-proof and water-proof performance, and can operate stably in muddy, dusty and damp field environments. After testing, its average mean time between failures can reach over 6,000 hours, and its lifespan far exceeds that of ordinary industrial-grade hydraulic motors. ​
