Dull Lawn Mower Blades? These Are Some Of The Best Tools To Sharpen Them With
By RON KING
File
Files are one of the simplest and cheapest tools for sharpening lawn mower blades. Suitable types include those with a coarse cutting profile known as "bastard cut."
Start with the forward end of the file near the base of the mower blade's cutting edge and firmly push the file away from you and along the cutting edge.
Angle Grinder
An angle grinder is much faster than a file, so long as you ensure it has a grinding wheel or flap disc suitable for removing metal.
Restore the lawn mower blade's edge by matching the angle with the grinder as quickly as possible to prevent overheating. Keep the number of strokes even on both ends of the blade.
Dremel Grinder
Dremel simplifies lawn mower blade sharpening with its "Lawn Mower Sharpening Attachment," boasted as "the fastest, easiest way to sharpen lawnmower blades."
However, it may not match the angle of your lawn mower blades. If it doesn't match, you'll have to manually adjust or change the angle of your blade.
