Franco, a visit to your local NH and Kubota dealers might help in your decision. You really need to get on the tractors, drive them, use the front loader a little, and generally see how you like each particular model. You may get on a 2910 and just fall in love, or operate a TC33 and find that it's what you've been dreaming of. Dealer personnel can provide you with detailed specs on each machine, front loader, and any implements you might be considering. Also, they're a good source for information in general. Just ask a lot of questions. I like to play the dumb consumer (not hard for me) when I'm gathering information for a large purchase. Talk with the service managers, too, about the tractors. They see things in a different light than sales folks do.
If a particular dealer doesn't seem right for you, find another one. If you're going to invest $20,000 of your hard earned money, you need to be comfortable with the dealer as well as the tractor. When I bought my Kubota (even though I ended up buying a privately owned used) I was looking a a
B7300 and asked the dealer for references (customers) who had purchased from him in the past year. He was straight up and gave me about a dozen customers who had purchased
B7300,
B1700, and
B2400 tractors from him. I called a couple and got the good refrerrals I expected, although one guy said he thought the service dept. was a bit slow with a warranty repair he'd had done.
All that to say, consider visiting local dealers, find a tractor that fits you and your needs, and buy from a dealer you're comfortable with.
