Maintain a log of all checks and corrective actions to support traceability and future maintenance planning.
Seasonal service intervals require more comprehensive inspections and component replacements to extend the life of the machine. At the start of each season, replace engine oil and filters using the recommended grade, and inspect the hydraulic fluid for contamination or viscosity changes, replacing as needed. Inspect and test the battery’s charge and health, including electrolyte levels if applicable, and replace aging batteries to prevent unexpected start failures. Examine the mower deck for wear on blades, spindles, and belts, and replace components showing excessive wear or damage to preserve cutting performance. Verify the condition of the fuel system, including the filter and injector lines, and replace any degraded parts to prevent fuel delivery issues. Finally, perform a full inspection of the cooling system, including hoses and clamps, ensuring there are no leaks or blockages that could lead to overheating during peak workloads.
