In winter, when temperatures drop significantly, the lubricant in a tractor can reach its freezing point, causing the transmission's rotational resistance to increase dramatically—often by more than ten times. If the tractor is started under such conditions, it can lead to serious damage, including crankshaft distortion and damage to the flywheel ring gear and other rotating components. So, how can you safely start a tractor in cold weather? First, it’s essential to warm up the tractor before starting. If the engine has stalled, turn off the oil in the sump and use charcoal or hot water to gently warm it up before attempting to start the next day. Never use an open flame to directly heat the oil pan, as this can cause the oil to degrade and the engine to suffer long-term damage. When the temperature is between -5°C and 0°C, you can preheat the engine using warm water. Heat the water to around 70–80°C and pour it into the engine for 1–2 minutes. Then, check the upper part of the engine for warmth. If there's no sensation of heat, drain the water and add fresh warm water until you feel the warmth. After warming up, start the tractor by engaging low gear first, then gradually shift to higher gears. If the temperature drops to between -15°C and -5°C, you can use a light charcoal fire to bake the oil pan for 10–20 minutes. While doing so, continuously turn the crankshaft until it moves smoothly. Check the fuel system; if boiling water isn't available, use hot water instead. However, the initial water temperature should not exceed 70°C before starting. When temperatures fall between -25°C and -15°C, it's necessary to bake both the oil sump and the bottom of the rear axle with a strong charcoal fire for about 15–20 minutes. Then, use boiling water to heat the fuel tank components, including the high-pressure oil pump, fuel lines, “three-filter,” vaporizer, and oil pump. Make sure the initial water temperature does not go above 50°C. Repeat the heating process as needed, ensuring all parts are properly warmed before starting. Finally, avoid using the starter motor for extended periods. The battery should only be used to start the engine for no more than 3 seconds at a time. If the tractor doesn’t start on the first try, wait a minute before attempting again. Prolonged use of the starter can drain the battery and cause long-term damage. By following these steps, you can protect your tractor from cold-weather damage and ensure a safer, smoother start during the winter months.
