I just bought a set of Scag OEM blades for my new Turf Tiger 61" deck. They have a dull edge, definitely not razor-sharp or sharpened at all. I also noticed that the blades on my new Turf Tiger are not sharp either. Should the dealer have sharpened the blades on the new mower and the additional blade set I bought? I asked the dealership and was told that I didn't want blades to be sharp... Huh? In the past, with my older Turf Tiger, I periodically had the blades sharpened and they were returned to me 'dangerously' razor-sharp... Thanks for your thoughts on this!
