# Daily Maintenance and Care for Agricultural Machinery

Agricultural Machinery Daily Maintenance Guide: The Key to Extending Service Life I. The Importance of Daily Maintenance Agricultural machinery (such as tractors, harvesters, rice transplanters, etc.) is the core tool of modern agricultural production. Scientific daily maintenance can significantly reduce failure rates, improve operational efficiency, and extend equipment service life. According to statistics, regularly maintained agricultural machinery can reduce maintenance costs by more than 30% while cutting unexpected downtime by 50%. II. Basic Maintenance Checklist 1. Pre- and Post-Operation Daily Inspections Lubrication System: Check engine oil, hydraulic oil, and gear oil levels; replenish promptly when low (original-grade oils recommended). Example: Tractors require an oil filter change every 50 working hours. Cooling System: Clean weeds and dust from the radiator surface; check coolant level (a 1:1 water dilution ratio is recommended in summer). Tires/Tracks: Check tire pressure (refer to the manual for standard values), remove stones from treads, and adjust track tension as needed. 2. Key Component Maintenance Air Filter: Clean the filter element every 8–10 working hours (shorten the interval in desert areas); replace immediately if damaged. Common Mistake Warning: Blowing a paper filter element directly with a high-pressure air gun reduces filtration efficiency! Fuel System: Use national standard diesel; drain water from the fuel-water separator daily (especially critical in winter). Drive Chains/Belts: Apply grease regularly and check tension (a deflection of ≤10mm when pressed with the thumb is optimal). 3. Long-Term Storage Maintenance Thoroughly clean the machine body and apply anti-rust grease to key metal parts; disconnect the battery negative terminal and charge once a month; retract hydraulic cylinder piston rods to prevent seal deterioration. III. Seasonal Maintenance Priorities | Season | Maintenance Focus | | Spring | Replace antifreeze with regular coolant; check seeder metering device wear | | Summer | Intensify cooling system cleaning; inspect belts for high-temperature aging | | Autumn | Lubricate harvester blades; calibrate monitoring sensors | | Winter | Switch to low-freezing-point diesel; install engine preheating device | IV. Common Failure Warning Signs Abnormal Noise: Bearing wear / poor gear meshing (accompanied by localized heating); Power Loss: Clogged air filter / carbon deposits on injectors (requires professional diagnostic equipment); Hydraulic Failure: Oil line leakage / valve body sticking (abnormal pressure readings). V. Professional Maintenance Recommendations Maintain a maintenance log: Record each service date, replaced parts, and fault conditions. Prioritize original parts: Aftermarket parts can cause over 80% of compatibility issues. Annual comprehensive inspection: Schedule a professional technician review during the off-season (including electrical system checks, hydraulic pressure testing, etc.). Conclusion Agricultural machinery maintenance is like a "regular health checkup" — the seemingly tedious daily upkeep is in fact the best investment to avoid major overhauls. Master these techniques, and your equipment will deliver peak performance during the busy farming season! (Note: Specific maintenance intervals should follow the equipment manual; this article applies to mainstream agricultural machinery.)
