Key components and how to service them
- Engine oil Use the grade specified in the owner's manual; check level with the dipstick when the engine is cool and evenly on a level surface.
- Oil filters Replace at each oil change to avoid bypassing contaminated oil into the engine.
- Air filter Inspect for dust and oil-soaked elements; replace as needed to maintain optimal air-fuel mixture.
- Fuel system Use fresh fuel, add stabilizer for storage, and inspect hoses for cracks or leaks.
- Blades Remove, sharpen, and balance; replace if chips or cracks are present to prevent vibration and uneven cutting.
- Deck belt and drive belts Check tension and wear; adjust or replace to maintain drive and deck efficiency.
- Grease points Apply manufacturer-approved grease or lubricants to front-end pins, steering linkage, and deck spindles as directed.
- Battery Verify voltage (aim for 12.6 V or higher when fully charged); clean terminals and ensure secure clamps to prevent starting failures.
- Electrical system Inspect fuses, wiring harnesses, and lights to ensure consistent visibility and safety, especially for early-season use.
