Sharpening mower blade


I was planning on trying to sharpen my own blade, but dont have a bench vice (or a work bench) for that matter. Is it a total mistake to wear a heavy duty glove on one hand and try to do it that way, one side at a time?

You could use a heavy glove on one hand to hold the blade while working the file with an ungloved hand. However if you have no tools or restraints for the blade it might be better to get professional help. You need wrench(s) to get the blade off and to put it back on securely. If you have an old tree stump sitting around you might brace the blade on it while sharpening, but not holding it securely will most likely do more harm to the blade -and probably you- than helping it.

Hmm, I have a torque wrench, got the blade off and know what to set it at to get it back on, I have also done all my other services (oil, air filter, spark plug), my lawn boy is reallly easy to work on. I do have a big stump in the backyard, maybe i will try that out, or maybe its time to cough up some dough on a workbench and bench vice, I am sure it will come in handy beyond this project.

Sharpening mower blade


"one swipe" of a gringers wheel (bench or hand held)on both sides and back parts very lightly.a wire wheel on the grinder bench there will clear the built up grass..nice and some what new....just note how you take it off and reinstall it should be stamped or nut washer rust mark.. will direct you.just put a slight sharpness video is cool he doing it with no fluids within the mower never tip a gas/oil filled one like this.you just need to tilt it slightly to break the bolt loose 6"piece of 4 X 4 works.i do both sides he only does one to get the angle... bos wrench works the best if your doing it blindreaching under it...vasaline the bolt going back in...

Is there an idiot-proof way to do this? The only thing I've ever sharpened before is a pencil. I'm not averse to buying new tools if necessary. I gather it's important that the blade stay balanced, and am looking for a method that helps a first-timer to do that, as well as avoid any other possible pitfalls of the process.

The only possibly-relevant tool I have is a 4.5" hand-held grinder. If a bench grinder is what it takes, I could get one. I'm also curious about gizmos like the Work Sharp. I figure these are the kinds of things that I could invest in and they would eventually pay for themselves, if they work well.

Or if there's a by-hand method that's better for a newbie (i.e. less likely to screw it up), I'm open to that too. Just looking for a method that uses readily-available tools and materials.

Thanks for any tips.
Over the years of doing professional lawn-mowing, all I ever used was a 4" angle grinder. Lock the blade into a bench vise and go to town. Grind it down to a nice sharp angle, not a blunt angle.

I also found that I could only sharpen blades once. If I sharpened them as second time, I just could not get a good cut out of them. So I sharpened them once, then replaced them the second time around.
