    Can someone describe with a little bit of detail, the procedure of sharpening lawn blades? The local shop charges $8 dollars to sharpen, so I usaully just by a new one for $10. I tried doing it my self once or twice, and it wasn't balanced correctly......... wound up breaking the drum on top of the crank on my lawnboy.
    Basically, what do you use to sharpen it, procedure for sharpening, and procedure for balencing it perfect. Also good info for newbies!

    Invest in a good blade grinder, and a balancer. There are several brands on the market RBG, Fireball, Lesco, Magna, etc. ;)

    lol ..

    I was looking at the MAGNA MATIC 9000 series blade sharpener.

    I was going through their www site and it seems like all I have to do to sharpen the blade is just put the blade in there and it does it by itself?

    Unlike the bench grinder I ahve to move it, angle it! blah blah

    - how did you break the mower with the blade being unbalanced not correctly sharpened?

    gotta link?


    I saw somewhere a jig for a drill gun. Holds it at the angle,all you do is slide b & F and then balence.

    On a 21" lawnboy, if the blade isn't balence properly, you wobble the shaft, causing all types of trouble. there is a small metal drum that bolts to the top of the motor, then the pull start bolts to that. When you pull on the pull start, the teeth come and grab the drum. The wobbling actually broke the drum. I've also heard of breaking a seal on the motor.
    I guess on a wb, it can be too good for the pulleys either.
