Understanding the Importance of the Right Belt Size

When I first started maintaining my Craftsman 46” mower, I quickly learned that having the correct mower deck belt size is crucial. A belt that’s too loose will slip and cause poor cutting performance, while one that’s too tight can lead to unnecessary wear on the engine and components.

Installation Tips

After purchasing the correct belt, I felt a sense of accomplishment, but I knew the job wasn’t done yet. Installing the belt took some patience. I followed the instructions in the manual closely, ensuring I routed the belt through the pulleys correctly. I also double-checked the tension to avoid any future issues.
