Or at least their own observations with the different blade styles... I run a Scag Turf tiger, 27 Kohler, 61" cut...just for my own mini farm...love the machine, but it's time to sharpen the blades that came with it...just made 100 hours...found a few rocks on the way...anyway, WHAT EXACTLY IS THE DIFFERENCE between the standard, high lift, and wide high life blades? I don't mulch the grass, just throw it. Are the "specialty" blades like raptors worth the $$$? Anyway, let me know what ya' think. Thanks!
