Sharpening lawn mower blades requires the right grit. The best grit ensures a sharp, long-lasting edge for efficient mowing.
Choosing the best grit for sharpening lawn mower blades can be confusing. Different grits serve different purposes. Using the correct grit prolongs blade life and ensures a clean cut. For general sharpening, a medium grit like 220 is usually effective.
For very dull blades, start with a coarser grit like 120. Finish with a finer grit, such as 400, for a razor-sharp edge. Regular sharpening keeps your lawn looking great and your mower performing well. Understanding these grit options can save time and effort in your lawn care routine.
