Bought a 2003 Scag Advantage Hydro last year, had been used one year. I know why the guy sold it. The cut has been subpar no matter what I do.This piece of cr@p will only mow good with brand new blades. sharpen them once or twice, or go to fast and is leaves stringers or a mowhawk in the middle. My old 36 Honda could have the blades sharpened 10 times rounded off and the cut was better than this scag with new blades. I also had to put 30 psi in one tire and 12 psi in the other (factory wheels never been replaced) to have them the same diameter measured by a string (mower was cutting lower on one side, this corrected that). I also have a Scag 48 that I have not had any problems with. Is anyone else having any problems with the 36 Scag Advantage Hydro?
