Due to the cold weather, the fluidity of the fuel deteriorated, the viscosity of the lubricant increased, and the water was prone to freezing, which caused many difficulties in the use and maintenance of agricultural machinery. Improper preservation of agricultural machinery in the winter can shorten the useful life of agricultural machinery. In order to improve the service life and economic efficiency of agricultural machinery, the following effective insulation and antifreeze measures should be taken.

1, tractors and other agricultural machinery should be parked in the garage as much as possible to prevent wind, sun, rain and snow erosion and freezing.

2, thoroughly clean the filter, oil pan, transmission, otherwise it will cause different brands of lubricating oil mixed, reduce the lubrication effect.

3, timely replacement of lubricants. As the viscosity of ordinary lubricating oil increases as the temperature decreases, resulting in poor fluidity, the frictional resistance increases when the machine moves, and the cold start is often caused when the tractor is started, and even accidents such as burning of tiles and axle suspension occur. Therefore, in the winter, oils in oil pans, air compressors and hub bearings should be replaced with lubricants used in winter; gear oils in transmissions, transfer cases, differentials, and steering gears should be changed. Gear oil used in winter.

4, thoroughly clean the fuel tank. In order to ensure the purity of diesel oil and reduce freezing, it is also necessary to clean the fuel tank frequently. It is generally required to clean it once every 20 days. It must not be brushed when cleaning, and it can only be cleaned with gasoline or diesel oil. If the inside of the paper filter element is found to be deformed or worn out, it should be replaced with a new one. The pressure regulator on the filter seat cannot be cleaned with gasoline, so as not to damage the sealing gasket of the pressure regulator valve. Conditions can be installed antifreeze fuel tank device, with oil tank insulation cover antifreeze, so that the tractor in the normal winter energy saving start and drive.

5. Add and replace antifreeze in time. Before using antifreeze, first remove the original antifreeze from the engine and then clean the waterway. It is best to fill the antifreeze specified by the manufacturer to avoid damaging the waterway in the future. In addition, the amount of antifreeze should be appropriate, and must not be ignored.

6, put the net cooling water. When the water is drained, the water release switch should be fully open (normally the engine has two discharge switches, one on the cylinder block and one on the outlet of the bottom of the radiator) and the radiator fill cover. After the water is drained, the engine can be started to run for a while. In order to drain the cooling water. In addition, the cooling system should be cleaned before entering the winter to prevent debris from clogging the radiator and the engine drain switch.

7. Regularly release the water in the fuel tank to strictly prevent the water from mixing into the diesel oil to prevent the diesel from freezing.

8. Properly increase the proportion of electrolyte in the battery, use the method of charging to keep the battery in a fully charged state, so that the battery will not lose too much capacitance due to low temperature and the battery shell will be frozen.
