So I know this is off-topic and it’s my first post, I did do a search and didn’t find this specific question being addressed. my son has a lawn maintenance business and I’ve tried a 6 x 48 Harbor freight belt sander but it’s just too slow even with a 36 grit zirconia belt. We’re using a 4.5” flap sander currentlily and it’s adequate. My question is would a 2 x 72 with say a 1.5 hp motor machine be up to the task of sharpening lawn mower blades? I’ve looked and looked at all the others that are out there and the Oregon Which is a rebranded burr king is a 1.5” x 48” at 8000 surface feet per minute and a 1 hp motor seems to be a high end machine and thus is pricey. On the low budget end Dayton makes a 3/4 hp 2 x 48 But only 4500 sfpm. It’s a lot less money, but I don’t know if it’s adequate to sharpen commercial ztr mower blades?
