I had a CASE 440CT (Tier II) for a few years. 89-93 hp, with Hi/Low speeds and auxiliary hydraulics. Picked it up cheap with 2500 hours. I replaced the final drives within the first couple hundred hours. Saved a ton of cash doing that work myself, but kind of a PITA to do without a proper machine shop and hoists, etc. It was an absolute tank that would do anything I wanted to do with it, within reason. Tracks weighed like 400# a piece. Toward the end, I had a track off and back on 6 different times in one day, and that's the day that I decided to sell it... If I ever get another track machine, the ability for it to hold onto its tracks will be one of my top requirements. Resetting a track might not be that bad if you've got another machine to lift your loader up and another set of hands to help you out, but resetting a track solo, especially in the muck, is beyond aggravating.
