When it comes to maintaining a lawn mower, one of the most crucial components to consider is the blade. A dull blade can lead to uneven cutting, increased wear and tear on the mower, and even pose a safety risk. However, the decision to sharpen or replace the blade can be a daunting one, especially for those new to lawn care.
