I have a new LT1050, not much difference between it and the 1046. The 1050 has a slightly larger engine and bigger deck but that's it.
I only have a few hours on it, but I am very impressed with it after mowing a half dozen times. Even though it has a large deck, it is very easy to maneuver around trees in the yard as it has a nice tight turning radius. The Kohler is much smoother than the Briggs I had on a previous mower, more powerful, and overall it is a very comfortable machine.
I looked at several brands before deciding on the CC, and I am not disappointed at all. I'm sure you will be equally impressed with your new 1046. Good choice - congratulations!
