1. Determine Your Needs

The first step in buying a new transmission belt for your John Deere L120 is to determine your specific needs.

5. Read Reviews

Before making any purchase, I always make sure to read reviews from other customers who have bought and used the product I’m considering. This gives me an idea of their experience with the product and helps me make an informed decision. Look for reviews on reputable websites or forums dedicated to lawn tractors.

Maintaining lawn tractors can be expensive, so it’s always wise to consider products that come with warranty coverage in case of any defects or issues with the product. Be sure to check if the transmission belt you’re considering comes with any form of warranty and what it covers before making your final decision.
