440 icd track adjusting

[Lavoy]

No 4 roller 440's manufactured, but I have seen a couple of torch job conversions.
They made a 4 roller 1010 partially because there were still ag crawlers available, and the 1010 was the only model built so to speak. If you wanted a 4 roller crawler when the 440 was built, you bought a 420 or 430. 440 buyers would have been commercial customers, not ag, so no real need to sell a 4 roller crawler, especially when they were still available in a cheaper model.
1010 and 350 both were available in 4 roller, but you don't see many, probably not a lot of farm customers left by that time.

I will look these over to see if a torch job.
Hope to get some pictures too.
Might be a very rare machine!

Outside chance it has had 1010 trackframes installed, but absolutely no chance it is factory.
