You don't say what you're mowing or how much or under what conditions. Plus there's a big price difference between the two. In general, a ZTR will be a bit quicker as long as you are on flat ground and especially if there are obstacles (trees, garden areas) to go around or lots of tight turns. Both have rather small decks (42") so if you have an acre or more, you might want to consider something with a bigger deck. Another thing to consider is the size of any gates you may have to pass through and what sort of storage space you have. BTW, do you have a Cub Cadet dealer nearby? I've heard good things about the LTX 1046 KW. A major consideration is if you have steep slopes or rough ground -- under those circumstances I would not not consider any of the above. Also keep in mind that these are lawn mowers, not tractors. They're not a good option for moving snow or pulling a heavy cart loaded with firewood; you'll wear out that lightweight hydro in a couple of years and possibly void the warranty.
I am cutting a little under a acre of mostly flat lawn with some trees....they are both the same price here in canada....due to storage space I have to stay with 42 inch deck. I did look at the cub tractors also but like the other dealers better....will not be moving snow ...have a walk behind blower.
