The noise of the tractor is so great that if the operators operate for a long time, hearing loss will occur and affect their physical and mental health. However, in the actual transportation operations, it is not uncommon for the operators to artificially increase noise. Some operators cut the exhaust resistance inside the muffler to reduce the exhaust resistance, resulting in greater noise. This practice is wrong. How to reduce the noise of the tractor? The author believes that as long as the measures are reasonable, it will be able to reduce the noise of tractors. Specific measures include the following: 1. Make sure that the tractor is always working in a good technical condition. 2. To ensure the complete and reliable operation of the tractor components, especially to install the exhaust pipe, because the exhaust pipe is mostly equipped with muffler, it will reduce a large part of the noise. 3. To prevent parts from loosening, loose parts can cause vibration. 4. Do a good job in the maintenance inspection of tractors. Add qualified lubricants and greases as required to prevent poor lubrication of relative moving parts and produce dry friction or semi-dry friction and increase noise. 5. To maintain a good fit clearance of the relative moving parts, according to technical requirements for assembly or adjustment. 6. Do not arbitrarily change the fuel supply. If the fuel supply becomes larger, the fuel injected into the cylinder will not be completely burned. This will not only waste fuel, pollute the air, but also increase the noise of the tractor. 7. The advance angle of fuel supply should be adjusted accurately. Because the accuracy of fuel supply advance angle adjustment will not only directly affect the performance of tractor power, but also affect the size of tractor noise. For example, when a tractor emits extremely loud sounds of exhaust gas, it is often accompanied by a "bang and bang" sound, which is caused by an excessive feed angle.
