All-Crop 60 Scrap/Save

I will probably be given a very rusty Allis All-Crop 60 combine. It has been sitting outside for so long that the bottom of the bin has completely rusted away. It has spoke type pneumatic wheels, and was sunken into the ground so far that the angle iron axle was 3" under the ground on the header-side before I dug it up. The good news is that the ground is sandy and well drained, so the rims and the angle iron frame are still intact (and look remarkably good). The tires are not useable and most of the external wooden and rubber parts are rotten and have disintegrated. It is complete, but most of the pulleys are rusted away on the bottom side. What should I save? It has the cutter bar and guards, a Scour-Kleen unit which is mostly-not-rusted through (one end cap has some rust holes that I can fix)(this unit has a 90 degree drive, sits sideways on top of the bin rather than front-to-back, and empties into the bin), and the metal screens (sieves?), chains, and wooden slats inside the machine look very good.
The back story: I got a job brush-hogging 20-some acres to knock down the golden-rod so that professional tree removal equipment could operate without radiator-clogging and oil-cooler-clogging problems. I spotted this combine and a few other implements along the edge of what must have been a field over thirty or forty years ago. The combine is close to what is undoubtedly an old barn foundation, and there is a complete case two row planter and a set of Allis mounted cultivators sitting next to it. I will be taking the cultivators and planter, but I don't have a good way to transport the combine. I am hesitant to haul it the 25 miles back home on the road, since I think I would loose most of the internal parts while pulling it. I am thinking that I might cut out everything that is savable and would fall off, and then re-tire it and pull it to the scrap yard on the road.
I don't have a way to get photos for everyone to see, but trust me, it is not savable, and you would be appalled at its condition. It is located in mid-Michigan.

I would say unless there are many usable parts its not worth the effort. Its not a real heavy combine so I doubt its worth much as scrap. Sounds like over the years it has lost weight so it has even lost scrap value.

The Scour-Kleen should be worth a few bucks, I don't have one on my AC 72.
