The use of tractors in winter
Before going into winter maintenance and wintering, in strict accordance with technical requirements, the tractor's three filters are carefully cleaned and maintained, and faults are eliminated in time. Adjustment oil specifications Engine oil grades are based on local temperature: Minimum temperature is 0 to -5 °C, select -10 diesel; minimum temperature is -10 to -15 °C, select -20 diesel; minimum temperature is not low At -30 °C, choose -35 diesel; the lowest temperature in the high-cold area around -40 °C, choose -50 diesel. Note tire pressure The winter tire pressure is about 5% higher than the summer requirement to reduce rolling resistance during travel. Preheating start Before the winter start, increase the engine temperature with hot water of about 80°C, and turn on the water release switch. When the hot water of about 40°C flows out, add boiling water to start the engine. When the temperature is particularly cold, stop the engine oil after the engine starts to start. Before heating to 40-50 °C and then add the oil pan; prohibited ignition, dragging, sliding slope, open flame car, add water after the start of the car, adjust the loose injection pressure and other wrong methods to start; start after the speed of 15 minutes When the water temperature reaches 40°C, it can be started above, and the water temperature can reach 60°C before it can be loaded. Strengthen the antifreeze The winter should be artificial insulation work on the tractor, such as the installation of insulation curtain, or appropriate fan belt to reduce the fan speed; boiling water, snow chains, etc. should be prepared, equipped with winter and summer switch the engine, the switch To "Winter" position. Note that when the temperature is below 0°C and the temperature is below 0°C, the tractor should release the cooling water when the temperature is below 0°C; but the water temperature should be higher when the water temperature drops below 60°C. Otherwise, the basic body or cylinder head can easily be formed. Deformation caused by stress and deformation; at the same time when the water can not leave, prevent the drainage valve due to impurities and plugging.
