Dump Trailer - another advantage of a trailer vs a dump truck is you can unhitch the trailer and drive your truck to go get supplies, go to McDonalds, etc.
Comfort - My NH TC25D has an adjustable seat. It can be adjusted for weight and it swivels, etc. It's very comfortable. When the dealer showed me these features I thought, why would I ever need those features. I actually remember almost feeling embarrassed by having such a seat. Well, I ended up buying the D model for other reasons but I am very glad I got the comfy seat as a part of the D package. I didn't realize what a beating my back had been taking until I had to use my old, faithful WheelHorse garden tractor. Don't underrate comfort when buying a tractor, particularly if you're going to be spending a lot of time on the tractor.
Dealers - You're on the right track concentrating on the dealer and the service you will receive. The best purchase price from a lousy retailer is a bad deal.
Oh, I think I recall a thread where even the green and the orange guys thought the blue tractors were the prettiest. All things being equal, go for great looks. /w3tcompact/icons/laugh.gif
