JD X300 mower blade sharpening

[Chazbo007]

Does anyone know of a professional lawn mower blade sharpener that can be purchased for personal use?

You may not like my answer, but most people I've seen just use a bench grinder. I don't know of a dedicated machine used just for mower blade sharpening. Some folks use a balancing tool to show whether they need to remove more metal off one side or the other for perfect balance. But like I said, the shops I've seen just use a bench grinder.

Thanks for you response. I know that most individuals use a bench grinder but I remember seeing a shop that use a machine where they fasten the blade to the machine and the machine uniformly sharpens the blade. It's been a while ago and that business is no longer around. I'll keep looking.

an angle grinder works well also. Northern Tool has a small grinder wheel for mower blades that attaches to a 3/8" drill. I take off what I think I need and then stick a bolt through the hole to check for balance. Good luck.

How much you want to spend?

There is the Oregon Blade sharpener, ranging in price from $650 to $1000 depending on where you look.

Or the cadillac Magnamatic 8000 for $1200. They also make a cheaper model if your only sharpening straight blades. Its about $650

I've looked at both the Oregon grinders and the smaller Dremel rotary tool but I was hoping there was a grinder made specifically for rotary lawn mower blades (and only rotary blades) that didn't cost an arm and leg. Maybe I need to design one.

If going into the business of sharpening, then a machine makes sense.

But for a single mower deck, a right angle grinder with a 4" diam wheel works great.
One can't invest too much in a grinder as new blades don't cost that much to offset the cost of buying new. If stones are hit, then too much has to be ground off to get a good sharp blade.
But the right angle grinder works well for me if just normal touch up sharpening is needed. Rock the blades or catch a piece of steel buried, then it is time for new blades. Sometimes I just buy the package of three, and only replace one if bent or rocked bad.

Pretty much the way I see it. ^^^^^

I use a 4" grinder or a bench grinder for mine.

What kind of 4" right angle grinder do you have?

I have a DeWalt. But there are several brands.
