I tested a 2050 vpat the other day. My opinion was they were underweight for the power. Spinning the track was too easy. After much discussion with the salesman, we decided it was closer to a 6N class. It doesn't have the weight of a T.
The other thing I would say is, and I am just guessing here, the track speed is mostly independent of load. Its kinda like you set the track speed at 2 mph and that's what you get, regardless of load. Tracks go 2 mph whether you are moving or not. For me, I am used to a TC tranny, where you can expect the tracks to slow and bear down under load.
I have heard the D7E runs the undercarriage off because it is constantly spinning, and I would imagine the 2050 would be the same. Maybe practice would help. If all you are doing is trimming parking lots and lawns, it would likely be awesome.
Otherwise great dozer I think, and great value too.
