drill holes down the center and air chisel them air tools like impact wrenches also help usualy they will break the bolts if you have no bolt heads to work with than pilot drill through the heads than Grab a 3/8 bit and drill the head off. an air chisel will help both with cutting bolts and nuts and also for driving out stubbern bolts that are stuck

also forgot that this forum needs pics so we can look and drool not just read which is work.
On my Bombardier SV-252, there were carriage bolts with lock-nuts, all hardened apparently, 888 if I remember...
They would not loosen even with an impact wrench, only strip the holes on the grousers. An impact gun with a pencil shaped anvil worked the best. But surprisingly, it worked better well rounded over than sharpened to a point. The technique was to come in at about a 45 degree angle on the top of the nut. It would loosen and distort the nut some. Then I hit the top of the bolt and it drove right out of the nut, no problem.
I tried many other methods, but this one came from an ex-Marine buddy who used a similar technique on bolts in the service. It was fastest for me.
Then replace all the bolts and nuts. I got mine from McMaster Carr, and they were cheaper than Fastenal.

I like your idea of an engine hoist!!
Bet it didn't even know it was there, from the size of the bucket...
Cool snowcat too...

Welcome to the forum! Nice looking Thiokol.
I wish I had a "quick and easy technique", but I don't.
Other than the ideas already suggested, I'd offer:
1.) Liberally spraying with penetrating oil a day or two ahead of time.
2.) Grinding the head off each bolt (assuming you have access to do that).
3.) Assuming the intention is to replace the belting, use an acetylene torch to heat the nuts. (Obviously be careful you don't catch the rubber on fire.) Some people poo-poo the use of heat, but if it's done right, it's amazingly effective.

I'm sure there are several ways of removing the track nuts/bolts, but some are quicker. I was able to remove a bolt in about 15 seconds using the impact hammer method above.
Penetrating fluid didn't help me much.
Grinding took a lot longer, and it seemed too likely to damage the grousers, plus I couldn't access the bolt within the track guides.
A torch was just messy, slow, and stinky.
I also tried just cutting the nuts off with a bolt cutter, until I broke the cutting edge off.
For sure try different methods, but I think you'll find the impact hammer to be best.
