In winter, the weather is cold and the temperature is changeable. Some agricultural machinery operators do not pay enough attention to the maintenance of tractors. They think it's OK to maintain them casually. But it's not. If the tractor maintenance can't keep up, it will cause unnecessary losses to farmers. Today, let's talk about the six precautions for tractor maintenance in winter. Six precautions for tractor maintenance in winter

 

1. Pay attention to seasonal maintenance. Before winter, descaling, cleaning, adjustment and lubrication shall be carried out on all parts of the tractor. Technical indicators such as valve clearance, fuel injection pressure and fuel injection advance angle shall be adjusted to the specified range, and the clutch, brake and control mechanism shall be fully adjusted to ensure that the tractor is in good condition and lay a safe foundation for winter.

 

2. It is strictly forbidden to start the tractor by wrong methods such as ignition, dragging, sliding slope, baking the car with open fire, adding water after starting the car, and loosening the oil injection pressure. The tractor is not easy to start in cold winter. If the above methods are easy to cause impact and damage to the clutch and gearbox gear, it should be started correctly. Low temperature starting fluid can be used to spray into the air filter, The injection time and injection volume shall be controlled before starting. After start-up, rotate at a medium speed, start when the water temperature reaches above 40 ℃, and work with load when the water temperature reaches 60 ℃.

 

3. Note that when starting without cooling water, do not add boiling water for the first time to avoid cracking due to sudden heat of the body. During the operation of the tractor, if the water tank boils or water needs to be added, pay attention not to add cold water suddenly. At this time, stop the operation. After the water temperature decreases, add clean drinking water appropriately to prevent the cylinder head and cylinder liner from cracking. Six precautions for tractor maintenance in winter

 

4. Pay attention to drain the cooling water. For tractors without antifreeze, drain the cooling water in the engine when the temperature is 4 ℃ or below, and when parking at night or for a long time. When discharging the cooling water, wait until the water temperature drops below 60 ℃, otherwise it is easy to cause damage to the engine body or cylinder head; It is not allowed to leave before the cooling water is drained. Be sure to check whether it is drained, so that the waterproof valve is blocked by impurities, and the remaining water expands abnormally and cracks the body at low temperature.

 

5. It is strictly forbidden to use unqualified diesel and engine oil. The brand of diesel used by tractors depends on the local temperature: if the minimum temperature is 0 to - 5 ℃, select - 10 diesel; The minimum temperature is - 10 to - 15 ℃, and - 20 diesel oil is selected; The minimum temperature shall not be lower than - 30 ℃, and - 35 diesel oil shall be selected; - 50 diesel oil shall be selected for high and cold areas with a minimum temperature of about - 40 ℃. Therefore, when selecting diesel oil, the freezing point shall be 5 ~ 10 ℃ lower than the local temperature. The engine oil used in winter has high viscosity, which makes it difficult to lubricate and start, so it should be replaced with No. 8 diesel oil; For the lubricating oil in the gearbox and rear axle, change 11 diesel engine oil or 20 gear oil.

 

6. Pay attention to bad driving habits, do not pay attention to driving methods, and operate in violation of regulations. For example, some agricultural machinery operators bang the accelerator before flameout, thinking that they can store some diesel in the cylinder, which is easy to start next time. In fact, this will only cause carbon deposition due to incomplete combustion of diesel in the cylinder, and may flow into the oil pan along the cylinder wall to dilute the engine oil, which will not only be of no benefit to the next start, but also affect the lubrication performance of the engine oil.

In addition, diesel oil is not added in time. Before flameout in winter, fill the tractor oil tank with diesel oil. Otherwise, the water vapor in the air in the empty tank will liquefy and condense into water droplets after cooling the tank wall, which will be mixed into the diesel, resulting in the failure of the engine to work normally.
