1. Ensure that the tractor is always in good technical condition.

2. Ensure that the working parts of the tractor are in good condition and reliable. In particular, it is necessary to install exhaust pipes, because most exhaust pipes are equipped with silencers, which will reduce a lot of local noise.

3. Avoid loose parts, which will cause vibration.

4. Do a good job in tractor maintenance inspection. Fill qualified lubricating oil and grease as required to prevent poor smoothness of relative moving parts from causing dry friction or semi-dry friction and increasing noise.

5. Adhere to the good fit clearance of relative moving parts. The driver must stop assembly or adjustment according to the technical requirements.

6. Don't change the oil supply at will. If the fuel supply becomes worse, the fuel injected into the cylinder cannot be completely extinguished, which not only wastes fuel, pollutes the air, but also increases the noise of the tractor.
