It transfers power from the final drive motor to the track chain, allowing heavy equipment to move efficiently across different working environments. However, many operators experience problems such as excessive wear, track slipping, abnormal noise, and increased maintenance costs due to poor-quality or incorrectly matched drive sprockets.
