Commonly Worn Out Parts

Several parts of the harvester are prone to wear and tear due to their constant use. Here are some of the commonly worn-out parts:

1. Knife Blade/Cutting Mechanism: This includes the main cutting blade, guard, and drive belt.
2. Threshing Drum and Concave
3. Separation Screen and Cleaning Fan Blades
4. Conveyor Chains and Sprockets
5. Rubber Tracks or Tires
6. Hydraulic Components: This includes hydraulic cylinders, hoses, and seals.
7. Bearings
8. Filters: Air filters, fuel filters, and oil filters.

Signs of Worn-out Parts

Several signs indicate that some parts of the harvester need replacement:

1. Poor Harvesting Performance: If there is excessive crop residue after harvesting or grain separation is not clean, it could mean that the threshing drum and concave are severely worn out and need replacement.
2. Decreased Power or Overheating: If the engine lacks power or runs too hot, it could be due to a clogged air filter or cooling system failure. You should consider replacing the air filter or repairing the cooling system.
3. Reduced Harvesting Efficiency: If the cutting mechanism runs slowly or the material's conveying speed decreases, it could be due to the aging and slackening of the transmission belt, chain, or worn-out driving gear. You should check and replace the corresponding belt, chain, or gear.
4. Difficulties in Movement or Increased Noise: If it is a rubber track harvester, if the track is loose or cracked, it needs to be replaced. If it is a tire harvester, if the tire is over-worn or burst, it needs to be replaced. Besides, if there is abnormal noise during walking, it may be due to bearing wear or damage, and you need to replace the relevant bearings.
5. Unstable Hydraulic System Operation: If the lifting or turning is slow or weak, it could be due to hydraulic pump, cylinder, valve, or seal failure; you should promptly check and replace the corresponding parts.
6. Large-scale Oil Leakage: Whether it is oil, hydraulic oil, or fuel leakage, it indicates that the seals are damaged or other parts are damaged, and you need to find the leakage point and replace the damaged seals or parts in time.
