Dealer adjusts till left and right blade tips at furthest outside point are the same height but still cuts 1" deeper on left side.The height adjustment is only on left side and is at max height. Deck is so warped the left front of deck is 3" lower than the other 3 corners. They said that does not matter but two problems. Left front wheel has to be on top hole and right on bottom hole to keep from forcing left wheel constantly to drag very hard into dirt, grass or concrete causing wheel to constantly come unbolted and destroying the wheel plastic. Then, the left blade is so angled down that it cuts a concave path. The blade may cut same at far outside tips but the tilted blade cuts an inch deeper before it gets to that part of the cutting deck. I was somewhat able to correct by raising the front excessive to bring the right blade to tilt back half as much as the left tilts down and it mows better. I think this should be a class action law suit as I went to Lowe's and all were that way. Any knowledge of others?
