I agree with the low sail-blades. I used some in the past from Precision, that are a spring or tool steel blade. Very flat, in fact I would mount them on my Foley 672 bedknife grinder and sharpen them similar to a bedknife. The only down side is, if you hit a root or rock they will shatter. They are much lighter and take some of the stress off the hydraulic motors and cut through thick grass a lot easier. My current fleet consist of JD 8800's and 7400 rotary mowers. To sharpen them I mill them on our milling machine so that I get the same angle on every blade, and a sharpened blade that looks like factory. I've been back and forth on grinding and milling, but after touching up blades that were ground, on my mill I see the inperfections and now prefer to mill everything I can. Good blades take about 3 to 4 minutes, and damaged and badly worn may take 5 to streighten out.
