    This is the best way to sharpen mower blades

    I tried filing and using a bench grinder but now I use a 90 degree hand grinder. Its the easiest cleanest and fastest way to sharpen thoses blades.(off the mower of course)

    I have to agree with you, Ive been using a 4 1/2 grinder for years on mine.
    Before that I'd use a large belt sander, which worked well but a slip would destroy an expensive sanding belt.

    I use a bench grinder except for one blade that wont come off the deck. For that blade I use a 4 1/2" hand grinder. Sharp blades make a world of difference in the quality of the grass cut and wear/tear on the mower.

    Love this new forum btw.
    What kind of grinder do you use?
    I have been using one that looks like overlapping sandpaper instead of a solid grinding wheel. This seems to work for me but I was wondering what you use.

    Doesn't seem like sandpaper would be strong enough but if it works then great! This is the hand grinder I use. $75 at Amazon.com

    The flapper sandpaper type wheels work great for rounding and smoothing metal, not what you really want for a blade.
    I use a regular metal cutting wheel on my 4.5 angle grinder.

    I started using Gator blades from http://mower-blades.agrisupply.com/s...%20Blades&rk=1 and have been very impressed with how little they need to be sharpened and how long they last.
    Cost a few bucks more but well worth it.

    Re: This is the best way to sharpen mower blades

    I have the same grinder as REKEES but I was wondering what kind of wheel you use. The wheel I use looks like sandpaper but it knocks out the bumps and knicks on the blades. It was what I had on hand and it seems to work. I will try a solid whell next time and see if there is a diiferrence.
    The solid wheels come in different grades /grits and I was wondering which would work best for this application of sharpening lawnmower blades.
