Inspect belts and hoses for signs of wear and replace them as needed. Additionally, replace the air filter every 100 hours or as specified in the manual. Following this schedule ensures reliability and extends the lifespan of your tractor.
5.2 Oil Change and Lubrication Guidelines
Regular oil changes and proper lubrication are crucial for maintaining the performance and longevity of your Craftsman YT4000 lawn tractor.
