I got a 42'' (smallest they make I think) Cub Cadet Zero Turn this year, my trusty Husqvarna tractor gave up the ghost. Loved it. Still got it, might put an engine in it some day.
I absolutely love the Zero Turn, just a blast to mow with and I actually enjoy cutting grass. Nobody knows I'm a derelict when I'm riding a mower.

The tractor is of course better if you tow anything but the zero turn is super fast. Probably half the mowing time but I tinker around and do a better job since I like riding it. Thought about finding a few neighbors I could mow to help pay for it and gas to boot, nothing so far.
