I just ordered and eliminator and terminator blade for my 21 to see how they do. ordered from here http://www.componentsplusparts.com/ They don't look too bad, but I am used to the suction and lift i get from my high lift blade. I typically discharge. The termintator blade is supposed to have more lift than the eliminator. I tried a gator a while back and was not impressed, took it right off. The cut was poor and the discharge was weak. If anyone has any opinions on the terminator or eliminator blades, please reply, would like to hear it, I am worried I bought another gator blade, don't want to waste the time. Hoping it has more lift than the gator.
