I have checked tire pressure, installed new blades in the correct orientation, and measured the deck on all corners to make sure its even with a 1/4" dip in the front. Its cutting uneven at all heights with it more noticeable the lower you go cause of the thicker grass. In the photo I mowed straight away from the camera. The right side blade is cutting lower when it reaches the middle of the deck. Any ideas on what is causing this? Only thing I can think it might be is a bent spindle. Wanted other opinions before I start replacing parts.
