In recent months, when visiting rural areas at the grassroots level, it's common to see farm machinery—such as pumps, diesel engines, rice thresher machines, and tires—left scattered in open fields, under eaves, or in backyard corners. These machines are exposed to harsh weather conditions, leading to peeling paint, rust, and damage over time. This not only reduces their lifespan but also results in unnecessary financial loss. It's truly a pity to see such valuable equipment left neglected. Currently, some rural households still face issues with improper storage of agricultural tools, especially during winter. Therefore, it's important to remind farmers that proper winter storage of machinery is crucial for maintaining its performance and longevity. First, for any agricultural machinery that won't be used for a long time during winter, it's essential to perform thorough maintenance. Clean the machine thoroughly, removing dirt, oil, and debris. Apply a fresh coat of paint to protect against rust and corrosion. Lubricate all moving parts and ensure they remain in good condition. This helps extend the life of the equipment and prevents costly repairs later. Second, it's recommended to store the machinery in a dry, ventilated, and covered area—such as a garage or shed—not in open spaces. This protects the equipment from theft, fire, and weather damage, ensuring it remains safe and secure. Third, during cold winter months, after completing work, it's vital to drain all cooling water from the engine. Whether it's a tractor, agricultural vehicle, or a combine harvester being stored for the season, make sure to open the radiator drain valve, cylinder water jacket drain valve, and water tank cover. Crank the engine to ensure all water is drained completely. This prevents freezing and potential damage to the engine block. Fourth, when starting an engine in cold weather, always use hot water to warm up the system. Begin by filling the radiator with about 70°C hot water. Once hot water flows out of the drain valve, close it and pour around 90°C water around the tank. When driving on icy or snowy roads, reduce speed, avoid sudden braking, and maintain a safe distance from other vehicles. Sudden acceleration or hard braking can lead to accidents or mechanical failure. Fifth, choose the correct grade of diesel fuel for winter use. Before the cold season begins, clean the fuel system and use diesel with a freezing point 5–10°C lower than the local temperature. Use low-viscosity diesel engine oil (No. 8) and allow the fuel to settle for 48–96 hours before filtering it through a silk mesh before adding it to the tank. Some operators mistakenly remove the fuel filter, which can cause clogging, damage to internal components, and reduced engine performance. This practice should be avoided to ensure smooth operation and prolong the engine's life.
