I have used the angle grinder on my old blades several times, but this year on my Kubota I decided to use the hand file and it worked great and didn't take very long.

I made a wooden wedge to get the correct angle and held that with the file to do the filing. Stored the wedge in with the file for future as well.

Now my blades weren't beaten up very bad and that makes a diference, but still wasn't too bad.

Getting the correct angle was the problem I always had with the hand grinder as each pass I seemed to so slightly different.

I have to agree. I end up doing my sets of blades and the "old-mans" So it takes me a about 1 hour to do about 12 blades with bench grinder (wire wheel blades clean first), and small 1" belt sander for dress-up work.

Just keep angle the best you can, do not break through heat treat (a few thousandths deep) and then balance when finished. Check with piece of paper when finished (or use finger nail ; with blade perpendicular)

Realizing you specifically asked for advise other than the use of a hand file, I recommend the file anyway. I use a 4 1/2 inch angle grinder on both of my bush hogs but a good hand file on both my Kubota 60" MMM with high vacuum blades and my walk-behind trim mower with mulching blade. I can get much better results with the hand file, and remove less metal in the process. Takes me about 5 minutes for the mulching blade, after I have removed it, of course. I do need to buy a good file about every other year however.
