If your mower’s losing power to the wheels or suddenly struggling to move even though the engine’s running fine, chances are it’s time to check the drive belts lawn mower systems rely on. I ran into the same issue — my mower started slowing down on inclines and eventually wouldn’t drive at all. Swapped in a new drive belt, and it was back to running like new.

What I’ve learned is that over time, drive belts lawn mower transmissions use can stretch, crack, or even snap completely. It’s one of those parts you forget exists until something goes wrong. Replacing it wasn’t too complicated — just make sure to match the belt size to your specific model and follow a good tutorial or your manual. Took me about an hour with basic tools, and I saved a ton compared to taking it to a shop.
