Can you guys that are experienced help me decide which blade and under what circumstances to use each blade. I have learned a lot while reading this site, but also learn so much that it leads me to more questions about some things too. I never realized how many different blades there were until I started reading here, and I also never had a good mower before. Is it better to stick with oem blades from Scag because they are better, or are they not better? I also see Scag offers straight blades, high lift blades, and also mulching blades. Currently for the fall leaves I have the chute blocker on and have NAPA razorback blades on and it seems to chew up the leaves really well. Of course I have never used any blades from another manufacturer other than the standard straight blades that came on my mower for normal mowing to compare. Somebody told me that the NAPA razorback blades are the same as Gatorback blades and are made by them. I have no idea. Does anybody know if this is true or not. I was just hoping someone with personal experience could tell me what brand is best under what circumstances. I also realize this is a lot or personal preference, but I really don't want to go out and buy $200.00 worth of different brand blades to find out what you guys probably already know. Thus far, all of you guys here have helped me a lot in making the decision on the mower I bought with no regrets, and I have no reason to think you would steer me wrong in blade choices either.
