Seasonal or annual service requires a structured approach to restore peak performance after long storage or heavy use periods. Change the engine oil and filter, replace the fuel filter, and inspect the spark plug for wear or fouling, replacing as necessary. Drain and replace hydraulic or transmission fluids if the model specifies these services, and test the hydraulic system for smooth operation without leaks. Perform a full safety inspection, including belt tension checks, blade condition assessment, and deck alignment verification. Record all actions with dates, operating hours, and technician initials to create a complete service history that supports compliance with manufacturer recommendations and guarantees safe operation during the mowing season.
