Sharpening mower blades

[dall]

you drive the nail in and set the blade on the nail if level its balanced if one side is lower then you take a little bit off the heavy side i usually take off on the back side of the blade it doesnt normally take much to balance

i use a 4 inch grinder with the flap wheel if bad or a sir sander with a 3 inch roloc sand wheel if just needs touched up

Sure

You can just go a tad more precise Easier w flap wheel

 

[dall]

the flap wheel doesnt seem to dig in so bad or add alot of heat to the blade

OK. I gotta go look for a flap wheel. Lol

Once you have sharpened your blades, what method do you use to re balance them ?

A piece of round stock (stick, rebar, wood dowel) and my eyes. My feet tell me if they're out bad enough to replace or reshape.

I have a Work Sharp Ken Onion edition that does a fantastic job on mower blades, shovels, knives, shears, etc..

Here's a pic of one.

How long does it take to sharpen ones made of good steel?

 

[dall]

probably 5 minutes per blade never really timed it

Any of them made of better steel that take more work has anyone noticed?

 

[dall]

Yes, the set of G6 blades I had on my old mower ground a little slower than normal steel.

 

[RI Chevy]

I can 2nd that on the G6 blades. Whatever they did for Fusion really hardens the steel. But once sharp, it stays sharp longer. [emoji106]

I use the fine wheel on my bench grinder or air powered die grinder. What I find most important is, maintain the original angle as much as possible, made easier by going slow and using a good light source. I have one of the little pyramid balancers but find my finger works just as well. Rocked out blades, I just resharpen and save for occasions where I might encounter more rocks. I use Stens high lift blades on all my mowers. They are cheap, easy to resharpen, and really spit out the clippings.
