sharpening mower blades

[brichter]

Anybody got any good tips and techniques for sharpening mower blades? I don't think I'm doing it quite right. This dry Pensacola Bahia grass is rough on blades.

BR,

I use my 6 in. belt sander to finish after roughing it in with the angle grinder. Miss. byhaia is also hard on blades.

I take 'em off and sharpen 'em on my bench grinder. I also got one of those little blade balancers for a coupla bucks that lets me keep 'em balanced, too. Whole operation with three blades off my deck takes about 15 minutes. I have some areas that I mow, that should probably still be bush-hogged, so I end up sharpening blades about once a month during the mowing season. 'Course I also mow 5 acres with it, this year a little more often than once a week.

I Sharpen My Mower Blades on my BENCH GRINDER. It puts a FINE edge on them and when you cut when it's DRY (as we all should) it runs through the grass like a hot knife through butter!

The best method that I have come up with, not only to sharpen rotary mower blades, but also sickle bar blades, is a 7" disc sander. I use a fine 120 grit disc.
The lawn mower blades are clamped in a bench vise while being sharpened.

The sickle bar blade is laid across 2 saw horses. I grind the RH edge all the way from one end to the other and go back and grind the LH edge.

It osunds as if everyone has a different preferred method. I have a steel table outside I use for welding, and clamp the blades to it and sharpne them with a 4 1/2 inch angle grinder.. as far as the type edge, my cutting is somewhat rough, so I don't try to put a real fine edge on them. Prefer to have a little more "meat" close to the edge. I pretty much try to match what they are like when new.
