I too have a much smaller model that what you're looking at, so can only give "general" Branson comments. I'm very happy with mine, it's done everything I've asked it for. I've had mine for just over a year, and have about 110 hrs on it so far. No problems or defects of any kind in that time frame, other than my factory battery (Interstate wet cell battery) died in the first winter. It gets pretty cold here, -40 F is frequently possible with no wind chill. That is really hard on batteries. It now has an Optima AGM battery in it, and is trucking along just fine. Other than that, not one single mechanical issue has come up.
My 3725 is cabbed, and I love the AC and the heat. Can be totally comfortable either pushing snow in winter (it's primary purpose), or brush hogging in summer (it's secondary purpose). It is one of the heavier units in it's class, has better FEL and 3pt lift stats than most other brands in the same class, and comes "standard" with some nice features that the other brands make you pay extra for. I had my rear tires filled with Rimguard, and with the FEL on the front, and a box blade on the back, my tractor scales at 7100 pounds on a CAT scale. That's some real useful weight right there. I can and have moved and fed large round bales with just the box blade on back for counterweight.
Come on down to the Branson forums and ask there too. I know there are some guys that have the model tractors you're looking at, they may miss your question up here.
