I have a newer 48" Fastrak that cuts very good. However, the blades do not line up perfectly. I mean, when I lift the deck and look, the right blade is about 1/8" higher than the middle blade. This is consistent with checking both ends of both blades. The left and center blade seem to be really close to the same height. I checked the right blade, and it is not bent. Actually I verified all the blades were not bent. Can I use a spacer to adjust the blade height so they are perfect? Or what are your recommendations? Thanks for the help, I bought my Hustler because of this forum!
