John Deere L120 Drive Belt Buying Guide

Understanding the Importance of the Drive Belt

When I first started maintaining my John Deere L120, I quickly realized that the drive belt plays a crucial role in the mower’s performance. The drive belt transfers power from the engine to the wheels, making it essential for effective operation. A worn or damaged drive belt can lead to poor performance or even complete failure of the mower. Knowing this, I understood the significance of choosing the right drive belt.

Identifying the Right Specifications

Before making a purchase, I made sure to check the specifications of the drive belt. The John Deere L120 requires a specific size and type of belt, and I found it helpful to refer to the owner’s manual for exact measurements.
