Hey all. I am the mechanic for our grounds crew and have been for the last couple years. I have a couple questions about how you all do your blade sharpening. Currently I use a dewalt angle grinder to get out as many of the nics as I can, then switch to a B.G.-121 rotary blade grinder. It usually takes me 15 - 20 mintues to do a set of 3 blades. I have 8 Toro 345 mowers with 3 blades each, 2 Exmark Lazer-Zs with 3 blades each and a Toro 4700-D with 7 blades. Plus the Land Pride with 9 blades. So a total of 46 blades. At 5 mintues each, thats almost 4 hours. Based on some of the other threads I have read, 60 blades runs anywhere from 1 to 1.5 hours. Plus, the 4700 blades have a twist to them so I cannot get a very good cut and the exmark blades are too long for the machine. I only sharpen blades maybe every 50 hours, maybe longer. Quality of cut doesn't really matter here, so long as they get the grounds done and the grass is short. I would prefer to keep them sharpened more but I would need to have an assistant just to do blades so I can keep up with all the other stuff they break. My supervisor has been talking about trying to get an automatic sharpener for me, but he has been saying that since before I got here. I have yet to see anything "automatic" in my searches. I see the Magna-Matic sharpeners and from what I read, are very good. Any ideas on automatics? Any ideas on my technique? Cliffs Notes: 5 mintues/blade = too long, automatic sharpener existance?, technique recommendations? Magna-matic 8000 or 9000? BTW, money isn't really a factor.
