Product Uses
The 45CC HST Pump is designed to drive the movement of tracked combine harvesters, excelling in scenarios where reliable traction and maneuverability are critical. It shines in muddy rice fields, lodging crop areas, and uneven terrain, providing the low-speed, high-torque performance needed for efficient harvesting while maintaining stability during fast transitions between fields. This hydraulic transmission pump is also ideal for supporting various hydraulic accessories on the harvester, such as cutting table lifting and unloading mechanisms, enhancing the machine’s overall functionality.
Specifically tailored for WORLD 4LZ-4.0E, 4LZ-6.0P, and 4LZ-6.5P harvesters, this pump is a vital replacement part for farmers and agricultural operations relying on consistent harvester performance. It caters to both small-scale family farms and large commercial agricultural enterprises, ensuring that harvesting tasks—from rice to other grain crops—are completed with minimal downtime and maximum efficiency. Whether used for seasonal harvests or year-round maintenance of agricultural fleets, the pump delivers consistent performance that meets the rigorous demands of field operations.
Product Operate Guide
Before starting the harvester, verify that the hydraulic oil meets the manufacturer’s specified standards to ensure optimal pump function. Inspect the pump and all connected hydraulic pipelines for signs of leakage or loose fittings, addressing any issues promptly to prevent system damage. Test the flexibility of control components, including levers and pedals, to confirm smooth operation without resistance, as unresponsive controls can impact pump performance.
Start the harvester’s engine and allow it to reach a steady operating state before engaging the pump. To control forward movement, press the forward pedal gently, and use the reverse pedal for backward motion—adjusting the pressure applied to either pedal regulates the walking speed. For hydraulic accessory operations, such as adjusting the cutting table or unloading grain, use the designated hydraulic control lever to direct pump output, monitoring the pressure gauge and listening for abnormal sounds to ensure smooth operation. Avoid sudden changes in speed or direction, as these can place unnecessary strain on the pump.
After completing harvesting tasks, reset the pump and all hydraulic accessories to their neutral positions before shutting off the engine. This prevents residual pressure from building up in the hydraulic system, which can cause wear over time. Regularly check the hydraulic oil level and quality, replacing the oil and filter element as recommended by the manufacturer. Keep the pump body clean by removing dust and debris, and inspect for signs of wear or damage during each maintenance cycle to extend the component’s service life.

Equipment functions The 45cc HST pump provides hydraulic power for the harvester, driving the walking and some hydraulic accessories to achieve forward, backward, and speed control operations. | Check before startup Check if the hydraulic oil level is normal (the hydraulic oil should meet the manufacturer's specified model).Confirm that there is no oil leakage or looseness in the pump and hydraulic pipelines.Confirm that control components such as levers and pedals are flexible. | Operation steps Start the engine and wait for it to run steadily. Control walking speed: Press the forward pedal to move the harvester forward, and press the reverse pedal to move it backward. Adjusting the pedal force or speed knob can control the walking speed. Hydraulic accessory operation (such as cutting table lifting, unloading, etc.): Use a hydraulic control lever to control the pump output and achieve accessory actions. Pay attention to the pressure gauge and operating sound to ensure that the pump works smoothly and without any abnormal noise. |
