Winter is the coldest season of the year, and the harsh weather conditions can pose significant challenges when operating agricultural machinery. It's also a time when agricultural accidents are more common. Therefore, it's crucial for operators and drivers to be extra cautious and attentive to prevent any incidents while using farm equipment.
1. Diesel fuel comes in different grades such as 10, 0, -10, -20, and -35, with the number indicating the lowest temperature at which the fuel will not freeze. For instance, diesel rated at -10 will not freeze below -10°C. When selecting diesel, make sure its freezing point is at least 5°C lower than the lowest local temperature. If the temperature drops to -5°C, using -10 grade diesel would be appropriate. In winter, diesel becomes thicker, making it harder to start and lubricate the engine. Therefore, it's recommended to switch from the 11-weight engine oil used in summer to the 8-weight oil suitable for winter. The lubricating oil in the transmission and rear axle should be replaced with a lighter grade, such as 11-weight diesel engine oil, and gear oil should be replaced with 30 or 20-grade oil.
2. Before starting the machine, it's important to properly warm up the engine. Begin by filling the radiator with water below 90°C, let it sit for a while, then gradually add warmer water until the temperature reaches around 30°C. Only after this should you add water that is above 90°C to start the engine. Avoid adding boiling water directly, as it could cause thermal shock and crack the engine block. While warming up, the oil in the crankcase should be heated with charcoal and diluted before being added back. Gently turn the crankshaft or rotate the flywheel to help the oil pump circulate. Failing to preheat the engine and water can lead to sudden temperature changes, causing damage to the piston and cylinder liner, or even cracking the cylinder head. Starting on a slope or using tractor traction can put unnecessary stress on the clutch and transmission. Without proper warming, poor lubrication may occur, increasing wear and making starting difficult.
3. After a safe shutdown, allow the engine to idle for a few minutes. Cover the radiator with an insulating curtain to help raise the water temperature above 40°C and ensure normal oil pressure before driving. Once started, drive at a low speed to warm up the oil in the transmission and rear axle housing before engaging in heavy work.
During winter, snow-covered roads can reduce tire traction, increasing the risk of skidding. Adjust your speed accordingly and avoid sudden braking to prevent sliding or tipping. If a skid occurs, steer in the direction of the slide and gradually correct it. When climbing hills, use an appropriate gear and avoid shifting mid-climb. On downhill slopes, maintain a steady speed—too slow may cause the trailer to push forward, leading to loss of control.
In addition to machine maintenance, it’s also essential to properly store and maintain agricultural implements during the off-season. Many tools remain unused in rural areas during winter, so taking care of them ensures they’re ready for the next planting season.
1. Prevent rust on metal parts. Most agricultural equipment is made of iron, and without proper care, it can easily corrode. To protect these parts, remove them, clean thoroughly, apply anti-rust paint, and store them in a dry, well-ventilated area.
2. Protect wooden components from decay. Some parts are made of wood, which can mold if not properly maintained. Clean and dry them before applying tung oil, then store them in a dry, ventilated place.
3. Prevent rubber parts from aging. Rubber components can deteriorate if exposed to moisture or oil. Remove V-belts, flat belts, and other rubber parts from tractors and cultivators, and hang them in a dry, well-ventilated location. When storing a tractor, lift the front and rear axles with blocks or jacks to keep the tires off the ground and maintain proper air pressure.
4. Keep motors dry. Agricultural machinery motors should be stored in a clean, dry, and well-ventilated area. Avoid storing them near pesticides or fertilizers, or in damp, rainy environments, as moisture can damage internal insulation, leading to short circuits, grounding issues, or even coil burnout.
