looks like a simple modification, a few rollers, channel iron and some extra chain links with grousers and your done.
Back about 1980, I got a wild idea. I had junked out enough old 3T D7s that I thought about building myself a high sprocket 3T D7 swamp tractor.
My idea was that I'd take a left and right track frame, trim and butt them together to give me 10 bottom rollers and an idler on each end. Then have the local metal shop roll me a tube from 1" steel to weld to the sprocket spokes with gussets to reinforce it and a bolt on sprocket ring on the outside. For shoes I was going to cut 22" shoes in half and weld to other 22" shoes for a total of 44" shoes.
Long story short, I was going to find center of gravity and shift the track frame to center the weight. With all that on the ground and 36" to 42" ground clearance it should have just about walked on water.
Don't laugh, back then I didn't mind welding. Burned 350 pounds of 1/8" welding rods to build a lowboy to haul up to and including D8s.
Our channel highlights machines from the earliest Holt and Best track-type tractors, equipment from the start of Caterpillar in 1925, up to units built in the mid-1960s.

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
