I think you are on the right track for determining what you need. The Boomers are "utility" sized tractors that pack a lot of features into a relatively small package. They have a short wheelbase and the most favored setup is with industrial type tires. The TN series is a much larger frame and not as "agile" as their smaller siblings. I suppose it's like choosing a crew cab pickup or an SUV. You have to look at the area where you plan to work, the jobs you will be doing, and even such things as transporting your tractor. For loader work, I think the TC55DA with that 18LA loader will be a real "Hoss." If you get the E-SS tranny, you will have most of the good features of a hydrostatic transmission in a gear drive. Unless I really needed 65-75 hp, I'd look closely at the TC55DA. You can't go wrong with either tractor. /forums/images/graemlins/cool.gif
...now if you want a cab, I'd definitely go with the TN. ...hmm
