When it comes to maintaining my John Deere LT155 lawn tractor, one of the most crucial components I needed to replace was the drive belt. After some research and personal experience, I’ve compiled this buying guide to help you make the right choice when purchasing a belt for your LT155.
Understanding the Importance of the Belt
The drive belt is essentially the heart of your lawn tractor’s power transfer system. It connects the engine to the transmission, allowing your mower to move efficiently. When I first noticed that my tractor wasn’t moving as smoothly as it used to, I quickly realized that a worn-out belt was likely the culprit.

Material and Durability
I found that the material of the belt plays a significant role in its durability. Most belts are made from rubber, but some may have reinforced fibers for added strength.

Replacing the drive belt on my LT155 was straightforward, but I recommend consulting the owner’s manual for specific instructions. I found several online tutorials that guided me through the process step-by-step. Be sure to have the necessary tools on hand, such as wrenches and a socket set, to make the installation smoother.
Maintenance Tips
After installing my new belt, I learned that regular maintenance can extend its lifespan. I make it a habit to inspect the belt for signs of wear every few months and keep the pulley system clean. This proactive approach has helped me avoid premature replacements.
