Lawn Mower Blade Sharpening Tool





Introduction: Lawn Mower Blade Sharpening Tool

I generally sharpen the blades for my 60 inch cut mower 5 sets per session.  The mower uses 3 blades, so that's 15 blades.  I use a Bench grinder but holding them while sharpening is a tiring, difficult job.   I thought, "There must be a better way of doing this."  I made this tool which consists of a pair of Vice Grips welded to an adjustable bracket that slides back and forth on a long rod mounted on the front of the bench, below the grinder.  It really works good.  Sorry I cannot furnish photos of it's construction, but I would be glad to take some more detailed photos of it if anyone is interested.

    Next time you take your blades off, put a little anti-sieze on the threads on the bolts. Makes it way easier next time. Remember a little goes a long way.

    Chris, if you can get the blade off, the best thing might be to take it to a shop and let them sharpen it. Grinders throw metal sparks that can put your eye out. You MUST WEAR EYE PROTECTION. I wear goggles that fit tight on my face and a cap to keep the metal grindings from getting into my hair and falling down from the top of goggles into my eyes later.

    Also there are very good prices for new blades on eBay. Just make sure you get the correct blade.....length, hole diameter, etc.

    I can see this having other applications if I ever get a bench grinder and I can see for that many blades free hand with an angle grinder just isn't going to practical

    My 1st grinder was an old washing machine motor with an arbor on it. That was in the 1950's.
    One of the main things this tool does is holds the blades at the exactly same angle every time. This helps lots & makes it easier to balance each blade.

    Thanks Penolopy. I like your hair braidings.
