Function
This gearbox is commonly referred to as the “secondary gearbox” or auxiliary gearbox, installed in the transmission system to support specific working sections such as:
Cutting system drive
Conveyor and feeding mechanism
Auxiliary power output system
Track or working device transmission (depending on configuration)
It works in coordination with the main gearbox to ensure smooth torque conversion and speed regulation, improving overall harvesting efficiency.

| |
Accept power output from the main gearbox or engine and distribute/transmit it to auxiliary systems (such as header drive, conveyor mechanism, track/wheel walking mechanism, depending on the model) | By combining internal gears, the speed and torque can be adjusted to adapt to different working conditions (such as high-speed operation of the cutting table vs. low-speed movement) | Provide rigid connections and bearing support for branch transmission lines to ensure stable operation of auxiliary transmission systems under load |

Product Operate Guide
Usage and maintenance suggestions
Check the oil level, oil leakage, abnormal noise or looseness of the gearbox before each season's operation.
Regularly replace the lubricating oil (it is recommended to use GL-4 or GL-5 heavy-duty gear oil according to the manufacturer's requirements).
Check if the installation bolts, key connections, and transmission shaft are worn.
If there is a decrease in cutting power, an increase in noise, or vibration during homework, the machine should be stopped in time to check the wear of the gears or damage to the bearings in the No. 2 miscellaneous gearbox
