How to Tighten Mower Blades
Lawn mower blades are connected to your lawn mower with a single bolt into the engine shaft. Over time it's possible that they can become loose. If you are mowing your grass and you hear a rattling sound coming from where the blade is, chances are your lawn mower blade could be loose. In order to save your lawn mower from possible damage, it is crucial to turn the lawn mower off and tighten the mower blades. Doing this is much easier and less expensive than possibly having to replace the lawn mower because it was damaged from a loose blade.
