In winter, the temperature drops significantly, and when it reaches the freezing point of the tractor's lubricant, the resistance during rotation in the transmission can increase by more than ten times. Starting the tractor under such conditions can cause serious damage—such as a bent crankshaft, damaged flywheel ring gear, and harm to other rotating components. So, how can you safely start a tractor in cold weather?
First, always 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 starting again the next day. Never use an open flame to directly heat the oil pan, as this can cause the engine oil to age or deteriorate due to high temperatures.
When the temperature is between -5°C and 0°C, pour hot water (around 70–80°C) into the engine block. After adding the water for 1–2 minutes, check the top of the engine for warmth. If there’s no sensation of heat, drain the water and add fresh warm water until the engine feels warm. Once warmed up, start the tractor using a low gear first, then gradually shift to higher gears.
If the temperature ranges from -15°C to -5°C, use a light charcoal fire to bake the oil pan for 10–20 minutes while continuously turning the crankshaft until it moves smoothly. Check the fuel system—if you can't use a boiling water pipe, add hot water instead. However, the initial water temperature should not exceed 70°C before starting.
When the temperature is between -25°C and -15°C, it's necessary to bake the oil sump and the bottom of the rear axle with a strong charcoal fire for about 15–20 minutes. Then, pour boiling water into the fuel tank in sections, heating all components between the high-pressure oil pump and the engine. Use hot water to fill the car, but make sure the first water temperature doesn’t go above 50°C. Bake the oil pan and rear axle for 20–30 minutes, and the gearbox bottom for around 15 minutes. All parts, including the fuel tank, fuel lines, filters, vaporizer, and oil pump, should be heated with boiling water until everything is functioning properly.
Lastly, avoid using the starter motor for too long. A battery-powered starter should only be engaged 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 damage over time.
By following these steps, you can protect your tractor from cold-weather damage and ensure a safer and smoother start.
