What Are Lawn Mower Blade Bolts?
Let’s start with a quick recap for those that need it. Lawn mower blade bolts are an essential part of your lawn mower!
The bolt connects your blade to the driveshaft of your mower, keeping it in place. It is a vital part of your mower and one that many of us don’t think about when we use a mower.
To understand more about blade bolts, we need to take a closer look at lawn mowers and how they work. The blade in your lawn mower rotates to cut your grass, so it needs to be held securely in place.
If it wasn’t, the blade could come loose. Not only could this lead to issues using your mower, but you run the risk of injuring yourself or others!
The blade bolt’s job is to keep the blade firmly in place, while also allowing it space to rotate to cut your grass. They also help to keep the blades balanced, giving you an even cut across your grass.
Your mower blades come balanced, but you might need to balance them yourself if you replace them, which is when you need to know about your blade bolts.
So let’s dive in and see whether the blade bolts are reverse threaded or not.

Bolts can be threaded either in a standard direction or reverse, with mower blade bolts either being threaded in reverse or standard too.
The same applies to the blade, with the blade and bolts in your mower usually being installed in different thread directions. But why? This is done to prevent both the blades and bolts from coming loose and coming off the mower.
