Are rear wheel spacers available from deere or kubota for their current series of compacts? On my old IH 154 the 3 inch spacers make a big difference in stability. Believe it or not this may be a factor in determining what I'll be upgrading to.

I don't think so. Most compacts seem to be real definite on how far out that the tires can be mounted, and I think their argument is based on some pretty good analysis as to what the material strengths of the tractor parts will support. My theory - and its only a theory - is that when JD built farm tractors built years ago, the abilty to size the parts was not as mature and so those tractors were way overdesigned. The overdesign allowed things like dual wheels and wheel spacers to come into being and they worked well.
Back to the modern compacts, I wouldn't be surprised if the wheel/tire position as designed is conservative. So if you feel (like I do) that your neck is more important than your warranty, then you might want to do some analyzing of your own and calculate your own spacers. ....

I have a JD4700 with 17.5L28 R4 tires. The combination of Rim and Hub positions allows for 7 tread widths from 51" to 75". The operator's manual recommends using the wide position whenever possible. Look for this capability when you evaluate your new tractor.

While I have never gone so far as actually testing the yeild strength of the material involved, I was told by a friend (read Kubota techie) that the strength of the hub MIGHT not withstand the additional torsional load created by putting the wheel further out than it was designed to be. While I know from working around a variety of machines that the hubs, etc., are all similar in size regardless of manufacturer, while the strength of the steel involved may vary, I suspect they're 'all in the same boat'. If it's any consolation, some of my employees have (mostly accidentally) had our 40hp class Kubota's on such side slopes that the seat-belt was literally the only thing keeping them onboard and they never even went as far as up onto 3 wheels. Best of luck. ....
