Before I bought my TC45D (first true tractor......My 12 hp Wheel Horse somehow just doesn't qualify) I spent about 4-5 months looking at several brands with compacts (JD, Kubota, CaseIH and New Holland). It finally came to the JD (4300 & 4600) or the NH (TC40D/TC45D). Each machine had its strong points and each had local support. This was important as I hoped to get the tractor from someone within 20 miles radius.
the JD dealer was knowledgeable, but was reluctant to let me 'test drive' one. Also, JD was noticably higher for a smaller tractor with fewer implements/bells & whistles (even after 30 days of dickering). Lastly, the JD dealer did nothing but bash the other brands....nothing good to say about anything but JD. While I expect pride in one's product, being so transparently biased made me wonder how truthful he had been with me on other questions.
The New Holland dealership was the exact opposite. Took a great deal of time with me, let me 'test drive', etc.. Suggested I speak to other NH owners to get thier thoughts as well. When it came time to talk price, I got a larger tractor, more implements, etc... While I still paid more than some others on this board, my price was was competitive with other dealers within about a 100 mile radius.
One Point the NH dealer made has stuck with me. He said that all of the companies I had looked at made good products. Each, including NH had had teething pains, some more serious than others. Lastly, he made it clear that he could and would beat JD's prices no matter what. Ultimately, after talking to several JD and NH owners, I went with Blue.
I now have 135 hours on my Blue and love it! No serious maintenance problems (very small 'cold' leak which is to be fixed at 300 hour service).
Good luck with your choice.
