Cub Cadet Mower LT50 Cutting Even Issue - Please Help

[Bburdette]

Hello,
I hope to get some answers on my new Cub Cadet XT1 LT50 that I purchased back in July. Ever since it was brought home it would not cut my lawn even. It leaves streaks of high and low grass. My lawn is pretty flat and I can’t figure out why. I called Cub Cadet and they referred me to a local authorized dealer to repair the problem. I took it to them and after having it a month it was discovered that the mower deck was bent. This was due to Tractor Supply loading it in the bed of my truck with a forklift. Then I had to wait over 2 more months for Cub Cadet to have a mower deck available to ship to the repair shop. Finally in Mid-November it was shipped and the repair shop installed it and called me to come pick up the mower. When I got it home I tried the mower out and it still was cutting uneven. I checked the deck level, tire pressure, etc. to make sure that it was ok and it was. I called Cub Cadet again and they told me to send it back to the repair shop and they would go over it again and check the frame to see if it was bent, changer the blades and check every possible thing that could be the cause. They came to pick it up the mower and kept it 5 days and brought it back to me after Christmas. They said the deck was off and the tire pressure was not right and that they changed all 3 blades. I was eager to try it out. Once again it was cutting uneven. I am so sick of this, I have called Cub Cadet about this issue so many times. I want to exchange it for another one but Cub Cadet seem to want to keep trying to fix this one, what else could it be? I am at my wits end with this. I spent good money for a mower I can’t use. I have added some pics. The lawn looks much worse than the pics show. Any Ideas?

Could it be the deck wheels not in the right position? My mowing height is the deck all the way up (set to 4).

Thanks,
