Don't understand the love for the high priced green paint when many other good manufacturers has comparable tractors and equipment and can even offer better service. There are many good choices that have been backed by years of experience. The biggest decision is to find the one you are comfortable with, the one other have owned and would recommend. I would also recommend looking at some used tractors, check them over to see what may have been repaired such as loader frame and mounts. A low hour used tractor may fit better than a new one, and not have the modern electronics and pollution trappings to put up with.
Yes name recognition is important but usually carries a slightly higher price, better parts availability, and hopefully a better quality machine.
Many of the old manufacturers were the innovators of modern designs ie Massey Ferguson the 3 point hitch, Cockshutt independent power take off. Yet some others brag they did it first.
But many of the main line manufacturers fell on hard times in the 80's when the farm economy tanked. Many have been bought out, combined with another, or just disappeared. Many of the older tractors still have new parts available on line or thru salvage yards. The more popular they were back then the more is available now.
In the end you have to choose what you feel best fits what you want to do and the one that is comfortable and just plain feels good.
