The first JD dealer that I went to was one that I had done parts business with before, but when I wanted to buy a tractor it felt like they weren't interested in my business. I left and have never been back.
At the second dealer I went to, I had a great sales experience and found their office staff to be outstanding with paperwork and financing. But then the shop really spoiled it when it came to setting up the tractor. They didn't have all the right parts, they didn't have a process for insuring that all the parts were in for a job until the tech was ready to do the work and then discovered that he couldn't. It was like the keystone cops. I finally had to demand that they deliver the tractor unfinished and take it back to finish the work after they were sure they had all the parts to do it. Then they still had to make a trip to my house to replace a fractured hydraulic line, and I had to redo some of the setup that was never right.
Bottom line: I hope that those in the process of reading this thread and buying a tractor have a good experience all around, no matter what you end up paying.
