There are four main parts of agricultural machinery maintenance:
1. Clutch bearings for agricultural machinery:

   In the work, the clutch is used very frequently and easily damaged. The clutch release bearing should be maintained before each season of operation. The main methods of maintenance are to remove the separation claw and the release bearing, and use diesel or kerosene to clean and dry. After that, install the grease and put it back on.

2, coulter shaft

    Bearing The right side bearing of the coulter shaft supporting the tractor is the same as the coulter gearbox. It is lubricated with gear oil. It is easy to ignore that the left side bearing should be greased. If it is not used, the bearing will run out of oil and dry up. The heat got stuck during the operation, and even caused the bearings to run inward, and the shaft journal was severely damaged and scrapped. Therefore, during maintenance, the bearing on the left side of the coulter shaft should be removed, and after cleaning, regularly add grease.

3. Shaft sleeve of harrow shaft

    The working environment of the shaft sleeve of the harrow shaft is very harsh, dust and moisture are mixed, and it is very easy to cause wear or necrosis. During maintenance, the impurities in the shaft sleeve should be cleaned before adding grease. If the shaft sleeve is severely worn, it should be replaced with a new shaft sleeve.

4. Thresher roller bearings
    The working environment of the threshing machine roller bearings is also very bad. There is a lot of dust and humidity. The maintenance work cannot be ignored. The roller journal will be worn, and the roller will be scrapped after serious. Before and during the operation, you should pay attention to checking the bearings. If you find that the grease becomes less or dry, refill the grease in time, and the bearing should be replaced in time when it is overloaded.
