Is the grinding disc that comes with this good for sharpening mower blades or should I buy another disc?

I have used to sharpen mine with disc provided but I would purchase a flapper disc maybe 80 grit.

from RD: I have used the chainsaw sharpener...which worked fine, but haven't tried with the lawn mower blade sharpener as yet.

I use a disk and its very easy to sharpen. I use it on sting rays when fishing. Just be careful not to hit a rock or any hard surfaces when using it. You might damage the edge. But again very easy to sharpen.

Mike: I have not used it to sharpen mower blades, but I am sure it would work just fine. I don't know of a jig that can be used, but even by hand it should work just fine, unless you want to sharpen rotary blades. In that case, not a clue.

Since I don't have both, your guess is as good as mine. Perhaps it is just about the fine blade, which I doubt I'd use anyway. The one I purchased has two blades, a coarse and a medium. Mine is entirely made of metal and built to last. I would never waste my money on a plastic grinder.

I would recommend the 4 1/2" Dewalt D28112 with dust shroud, the cutting and grinding wheels are less expensive and you can get closer into the corners, both have duty cycles so you have to watch the temp on the grinder. (just feel the housing) for the cost the manufacturing warranty is all you need it will cost you more for and extended warranty the to just replace it. Good Luck

I have them done locally, and they do a great job for $5 per bladeset. Once sharpened, though, the lifespan drops dramatically, so I only sharpen them once then chuck them. You can try doing it yourself with a grinder, but it's tricky and a good grinder is expensive. Watch for sales (pet supply stores, vet supply, horse supply) and stock up when you can.

Actually, the trimmer making a grinding noise is a GOOD thing, as it is the sound of the blade being sharpened as it cuts. Remember, this is a self-sharpening blade, which means that you do not have to keep replacing the blades as they become dull from prolonged use.

You would realy have to look atthe grinder model you have, does it have a switch for different speeds? Does the model label state the RPMs if it is fixed? If so is the speed(RPM's) higher than the ratings of the polishing disks?

yes the course grit will work quickly and put a fine, lasting edge on your lawn mower blades(you will have to do your part ~> which requires effort) but I've no doubt you know that. ABOUT THE STONES - THEY ARE EXCELLENT YOU WILL BE WELL PLEASED

I use my mower quite often, and the blades are still cutting well.I will sharpen them, before I put the mower away for the winter, so I think that once a year would be sufficient for blade sharpening.

You can buy a mower sharpening wheel at a hardware store and use it on your drill.

I am going to revise my answer a bit and suggest that you turn your sharpener on and clean the ceramic discs by pulling your felt pad towards you The diamond rouch sharpenning wheels eat the felt up and you would be best by using some compressed air (from a compressor not a can )or a vacuum with a thin areas attachment. If you want to run a piece of material on the rough sharpenning use some denim gently to pick up the fragments and metalic dust.with the pad instead of felt. Chris Mar

If you know how to sharpen lawn mower blades using a grinder, there is no reason to not use this one.

Only if the blades come apart. And regardless, spend the extra money and get one with the grinding wbeels

This is not the tool to sharpen lawn mower blades. A bevel grind will ruin a lawn mower blade (ask anyone who sharpens them for a living). I took mine to pro after destroying it with the work sharp. He took one look and asked "so why did you try to sharpen this with a belt?" He went on to speak in glowing terms about this grinder... for knives. He just couldn't believe I was dumb enough to think it would work on my mower blade. So, I have pink ears, you can avoid this fate. GET A FILE!

As I recall, it came with an abrasive disc for grinding metal. I bought more right away.
