11 Precautions for Tractor Autumn Maintenance

1. Avoid prolonged exposure to sunlight or rain in autumn. Tractors that have not been operated or are temporarily idle should be parked in a dry and ventilated place. Otherwise, the paint surface of the tractor will lose its luster, even bubble or peel off due to wind, rain, and sun exposure. Long term exposure to sunlight can also cause tire aging and even rupture, shortening its service life.
2. Overinflation is not recommended for autumn tires. Overinflation of autumn tires can cause the inner tube to rupture due to thermal expansion of the gas. Therefore, the inflation pressure of autumn tires should be 2-3% lower than the specified value.
3. Choose oil correctly. In autumn, when the temperature is high, diesel with a higher pour point can be used. In addition, special attention should be paid to preventing oil leakage in the fuel supply system, as oil leakage not only causes waste but may also lead to fires. Except for diesel. Lubricating oil and grease should also be selected according to regulations for autumn use.
During autumn operation, the cooling system begins to circulate forcibly, and the cooling water in the cooling system consumes quickly. During operation, attention should be paid to checking the water level frequently, and if it is insufficient, clean cooling water should be added in a timely manner. When the water temperature exceeds 95 ℃, the vehicle should be parked and unloaded. Do not immediately turn off the engine and stop running it. You can use the method of idling the engine to cool down. During the operation of the locomotive, if the water tank boils or water needs to be added, cold water should not be added suddenly to prevent the cylinder head and cylinder liner from bursting. At this time, the operation should be stopped, and clean soft water should be added appropriately after the water temperature drops.
5. Clean the cooling system in a timely manner to prevent water leakage. Before the arrival of the autumn harvest season, a thorough descaling and cleaning work should be carried out on the cooling system to keep the water pump, radiator, and water pipes unobstructed and ensure the normal circulation of cooling water. Fill the cooling system with 75-80 grams of alkaline water per liter of water, let the engine run for 10 hours, and then drain it completely. Rinse it clean with clean water. In addition, weeds adhering to the surface of the radiator should be promptly removed.
6. Keep the battery vent open. General batteries generate hydrogen or oxygen gas during use, which expands at high temperatures. If the vent is blocked, it can cause the battery to rupture. Therefore, regular inspections are necessary to keep the battery vent open. In autumn, the moisture in the battery electrolyte is prone to evaporation, so attention should be paid to checking the liquid level. The normal liquid level should be 1-15 millimeters above the electrode plate, the electrolyte density of the battery should be reduced according to regulations, and the ventilation holes on the filling port cover should be unblocked. Temporarily unused batteries should be stored in a cool and ventilated place.
7. Handle "boiling" with caution. The correct method is to run the engine at medium speed, open the radiator cap, release hot air, and slowly add cold water after cooling down. When opening the radiator cap. You should stand in the upwind position and not face the water inlet to avoid being burned by the hot water vapor sprayed out.

8. Pay attention to the tension of the belt. The fan belt is too loose and prone to slipping, which can cause a decrease in the speed of the fan and water pump. Reduce heat dissipation effect: If the fan belt is too tight, the bearing load will be too high, causing increased wear and power consumption. The general requirement is that when pressing with the thumb in the middle of the belt, the sag should be between 10-15 millimeters, and any looseness or tightness should be adjusted in a timely manner.
9. Proper use of temperature control devices There are two types of temperature control devices: automatic (such as thermostats) and manual (such as insulation curtains and blinds). Some drivers believe that in the hot autumn weather, the lower the water temperature, the better, and often remove the thermostat. Doing so will greatly extend the engine's warm-up time during cold start. Accelerate the wear of parts. Therefore, the thermostat should not be removed in autumn. Insulated curtains and blinds are used to regulate the airflow through the radiator. In autumn, insulated curtains are generally not needed, and blinds should be placed in the fully open position.
10. Prevent fuel air resistance. The higher the fuel temperature, the faster it evaporates, making it easier to form air resistance in the fuel circuit. Therefore, in autumn, the fuel filter should be cleaned in a timely manner to keep the oil circuit unobstructed; During driving, cover the fuel pump with a damp cloth and regularly water it to keep it moist. Reduce the generation of air resistance. Once the fuel system experiences air resistance, the vehicle should be stopped immediately to cool down, and the manual fuel pump should be used to fill the fuel circuit with fuel.
11. Engine explosion prevention: Engine explosion caused by overheating can increase the wear on the upper part of the cylinder by 3-5 times. Therefore. Thoroughly remove the carbon deposits in the combustion chamber, valve seals, and other areas, and check and adjust the fuel supply amount and time to prevent detonation.
