Ron - welcome to tbn. As an engineer myself, I love to compare stats. If nothing else, you are confident that you are comparing different brands as "apples to apples". That said, don't make a decision based on turning radius. Every compact I've driven - New Holland, Deere & Kubota has awesome maneuverability. Also a 100# more or less lift capacity makes little practical difference.
Test drive the machines and see which one you like. How is the visibility? are the controls easy to reach? Most importantly, how is the dealer?
Good luck & enjoy your new property.
