Rear Finish Mower Sharpening blades on RFM

[cisco]

Jackstands and angle grinder for touch up every 10 hours or so of field work on weeds and such; 3/4" impact wrench (1 and 13/16" nuts for my Woods unit - forget about a 1/2" impact wrench - I've got one for auto stuff, and it didn't budge the nut at 130 psi) and a bench grinder after heavy work. You are not supposed to put a fine edge on these blades (mine weigh about 20# each, which is typical of medium duty units), but rather a modestly rounded edge without major ding defects - like where you've hit major stumps, rocks and such.
