Jerry:
Read the Kioti letter in your post. Wonder about the confidentiality part though. The letter is short and politically correct so it leaves a lot to conjecture.
Coincidentially:
A couple of years ago General Motors sued Triumph Motors, Hinkley, England for trade name infringement. They (GM) alledged that the name "Bonneville" was property of GM and that Triumph LTD could not use the name. That's funny, Triumph, Meriden, England whom all the rights were bought by the new Triumph LTD, mainly Mr. John Bloor had the Triumph Bonneville model motorcycle years before GM ever badged their car a "Bonneville".......they lost.
I have stated in the Kioti forum that I feel Kioti's largest (present but not next year) tractor is a fine unit. I'd have considered one but the pto power was a little too low for my farming needs. I wouldn't ever say anything bad about a Perkins Diesel, I have one in my Massey and it's bulletproof but then, so is Kubota's engines. Why else would most manufacturers of power equipment that utilize diesel engines use Kubota power units for power, i.e: Bobcat, Generac Power Systems, Grasshopper, etc.
I don't think you can compare a model of Kioti to a model of Kubota. It's all about what the end user wants, dealer support and price and not in any order.
