Buying Guide for John Deere L120 Deck Belt

Understanding the Importance of the Deck Belt

When I first started using my John Deere L120, I quickly learned that the deck belt plays a crucial role in the overall performance of the mower. The deck belt connects the engine to the blades, allowing them to spin and cut grass efficiently. If the belt wears out or breaks, my mowing experience can become frustrating and ineffective.

Identifying Signs of Wear and Tear

I’ve had moments when I noticed my mower wasn’t cutting as well as it used to. It’s essential to be aware of signs that indicate the deck belt might need replacement. Some common signs include frayed edges, cracking, or if I hear a squealing noise when the mower is in operation. If my mower starts to struggle or if the blades don’t engage properly, it’s time to inspect the deck belt.
