I've been battling an unever deck (Turf Tiger Advantage) for several weeks now and still haven't figured out the problem. With all tire pressure checked and uniform, my mower is cutting shorter on the right side than it is the left. I measured the right and left side height of each blade and the results were curious. Measuring from left to right (as you sit on the mower), here are my left and right measurements on each blade: 1. 3 3/8" -- 3 7/16" 2. 3 1/2" -- 3 1/4" 3. 3 3/8" -- 3 1/8" It's not a consistent decline from left to right, which is what has me confused. Otherwise, I could simply level the deck. It's almost as if #2 and #3 need shims under one side of the bearing assemblies. Has anybody done that before? I don't think it's a bent blade shaft, because it would then cause one whole section to cut lower. When measuring, I double checked the measurements by rotating each blade half a turn and the measurements came out basically the same. I also measured with a different set of blades with the same result. Any ideas?
