My old man restored a Thiokol 601 Trackmaster when I was a kid.
With that short/small of tracks, it is going to suck in any deep powder snow.
Probably powered by an industrial Ford straight 6, 200 cu in if I remember right. Really gutless.
They had a proprietary steering diff setup where they had a box off the back of the t-case that then split into 2 driveshafts/diffs. Very complicated and impossible to get parts for. He ended up swapping a newer Piston Bully rear diff/steering setup into it, which was a whole nother can of worms.
Long story short, worth it to buy something a little more modern.
