    Just a couple of questions about blade sharpening:

    What is the best angle to sharpen blades at?
    What kind of grinding wheel is the best?

    Well I will put my 2 cents in on the first question. I try to sharpen my blades at 30 degrees.

    Second question you are gonna get several different answers to this one. Each one will tell you this is the best method or the easiest.

    Me -- I use an angle grinder with a 60 grit flap disc.

    1, less than a 90 degree angle
    2 a hard one.

    I sharpen blades by hand on a bench grinder with the coursest wheel I can find. I just follow the original angle that was on the blade when new. Sometimes I grind them back a little farther.

    Use a hand die grinder with the blade on the bench. Works great. Also the pitch should be at a 30-35 degree angle depending on the mower manufactor.

    Ive been trying to get good results with a hand held grinder and even a file. The fact is, they just dont cut as well or last as long as a proffessionally sharpened blade. Google rotary blade grinder and look at the Brandlein Fireball series, RBG by Wall, and Magnamatic. My favorite is the Fireball. These are expensive but if you mow commercially it will easily pay for itself in a year or two. Lots of people swear by their handheld grinder. I tried it and I no like.

    if you do it frequently, a hand file works fine. if they are really rounded or knicked, a grinder is almost required. seems to me Walker calls for 20 degrees on their blades, they don't seem to have as much angle as my emark oem blades did.

    If you use a handheld grinder to take out nicks, good luck with the angle.
