Most overseas agricultural areas have distinct four seasons with huge temperature and humidity differences. Farm machinery fault rates rise sharply during seasonal restart and working condition switching. Many farms only focus on equipment usage during farming seasons and ignore off-season maintenance, resulting in difficult startup, insufficient power and oil circuit blockage, delaying farming schedules and causing crop yield losses. Core seasonal maintenance includes replacing temperature-adapted oil, checking battery status, cleaning weeds and dust, lubricating hinge parts and inspecting farm tool interface tightness. Focus on heat dissipation and rust prevention in summer, and anti-freezing and circuit protection in winter. Comprehensive seasonal maintenance eliminates seasonal wear hidden dangers and ensures full-load stable operation during peak farming periods.
