When I was first tractor shopping I went into it with the idea that I wanted a Kubota. A friend had one and loved it. The Kubota dealer was literally just half a mile down the road from me and was an old HS classmate. Our sons had been in the same school for a year together, too. I was, for lack of a better term, pre-sold.
I bought a John Deere. Here's the story. I'm tall and I got on the Kubota and the rocker pedal set up for their hydro transmission was very difficult/painful for me to operate after a very short time. I knew I'd never be able to use the machine for more than an hour without a serious break. I then looked at Deere.
The pedal system was far more comfortable for me but the lever to operate the loader bucket was poorly designed and placed for my long legs (the Kubota's was fine). I read online of someone having a similar problem and solving it simply enough so I went with the Deere because it "fit" me better.
My point is that you should try to use or at least drive the models you're considering. You might be surprised to find that one just seems more comfortable than another for you. Believe me, after you get a few hours on it and have some dings, scrapes and scratches and have replaced a few lenses that branches knocked out the brand isn't going to matter near so much to you as comfort and ease of operation.
Good luck with whatever you decide. I hope this helps. /forums/images/graemlins/smile.gif
