If your mower deck isn’t lifting right or the blade engagement feels off, don’t overlook the lawn mower tension spring. I spent weeks trying to figure out why my deck was sagging and my blades weren’t engaging consistently — turns out the tension spring had lost its bounce.
Replacing the lawn mower tension spring was a total game-changer. It’s one of those small parts that does a big job, keeping the right amount of tension so everything runs smoothly. Once I swapped in a new one, the deck lifted properly, and the belt tension was finally back where it should be.
It’s an easy and inexpensive fix that can save your mower from more serious wear. Just make sure you get the right size and fit for your model. A strong, properly installed lawn mower tension spring can make your whole mowing setup feel solid again.
