How often do you replace the blades on your mower?
Do you have a small lawn and survive an entire year with one set of blades? Or are you a commercial landscaper that is left with dull blades by the end of every week?
Regardless of how often you mow, your blades can easily become dented, worn, bent, and damaged either over time or as a result of hitting objects such as woodchips and rocks. You should regularly inspect your blades, as broken blades can quickly become dangerous projectiles and can also potentially damage your mower.
Before attempting to inspect or replace your blades, consult your owner’s manual for information regarding safety, warranty, and specifics about your model. Remember to always wear heavy protective gloves when working with blades.
