Snapper Pro leaving a little mohawk

Well, ,my father and I "sharpened" my blades and now there is a little mohawk on the left side of my deck..... What do you think happened? Also, what is the best technique for sharpening blades? I know this probably a dumb question, but I'm having problems.

I'm guessing the tip of the blades is slightly rounded. Could be lots of other possibilities, but start there. As to proper techniques, again lots of options. What do you have readily available? Bench grinder, angle grinder?

Bench Grinder is all I have. I'm still 17 so I haven't compounded many tools yet. I have my Dad's bench grinder. But it stinks from what I can tell. I don't think it spins fast enough to get them sharp enough.

A bench grinder will do fine. It turning slow should help keep you from overheating the edge. There's tons of threads on here about sharpening. A pictures worth a thousand words. If you post a pic (or pics as you progress) I can help you get it cutting well. First remember, we aren't sharpening a knife or razor here. We're trying to re-create as close as possible the original profile. Have a look at a new out of the box blade. It's not that sharp. Note that a new blade has square corners? I suspect your blade tip has worn a bit, and the tips are slightly rounded.

I use the Dremel tool sharpening attachment that comes with the chainsaw, mower, etc... kit. Costs around $12. Takes less than 5 minutes a blade from removal, sharpening and reinstalling.

Hello All,

If you'd like some information on the correct angle and geometry of sharpening lawnmower blades. Most people do not pay enough attention to the angle and correct TIP. Often people spend most their effort in getting a razor edge and ignore grinding the TIP back to square. The TIP is the cutting tooth, and when a blade wears, the TIP becomes a radius. Sharpening a lawnmower blade requires you to grind the TIP back to get a cutting tooth again. Because a lawnmower blade is measured from TIP TO TIP, when a blade is very worn, when the TIPS have become rounded, the blade is shorter than if it would be sharpened correctly. See more info below.

See last two pages of our catalog here:

Thank you,

I have a Magna Matic and love it. Plus it's a lot safer then a bench grinder.

Hey Guys, sorry for the late reply, thank you for all the input! I have figured out the problem for the most part. I am getting alot of grass clumping under my deck and it is causing alot of lift loss.
