It is responsible for providing effective cooling for the gearbox, preventing overheating and ensuring the stable and lasting operation of the gearbox. Efficiency: The design of fan blades is reasonable, which can effectively guide the air flow and improve the heat dissipation efficiency. Durability: made of high-strength materials, it can run for a long time in various harsh working environments. Stability: Through precise manufacturing technology and balanced design, the fan blades are ensured to be stable when rotating at high speed. Noise control: optimize the design to reduce noise and improve the comfort of the working environment. The cooling fan drive system of tractor gearbox transmits power to fan blades through transmission devices (such as belts and gears). When the engine is running, the fan blades start to rotate to guide the air flow and transfer heat from the gearbox to the air, thus achieving the cooling effect. Installation: Before installation, check whether the fan blades and the drive system are intact, and ensure that the installation position is correct and the fasteners are fastened.
