I'm looking at buying a TD7G crawler. It has a blade, and I see all of those number crawlers have blades. I prefer a bucket. What is the differentiation in number to designate a bucket version? Also is it possible to buy a bucket and lift mechanism, and install on a crawler with blade? I am finding dealers don't know this information. I live in Dubuque Iowa area, would like a medium size loader crawler, 70-90 hp, comparable to a JD 555, I'm somewhat familiar with those. It is easier to look at local machine.
If you scroll down farther, there is a track loader section.
I don't see it yet, you suggested to scroll down further?
It's in the earth moving equipment between wheel loaders and backhoes
Go to "forums" on the top left, and you'll see all the forums listed. https://contractormag.co.nz/classic-machines/the-175-payloader/ here's an explanation of the vintage International crawler loaders.
Same drivetrain but a loader frame is completely different from a dozer frame.
