(quoted from post at 11:20:38 01/13/22) Thank you for asking a probing question - one that goes to the root of my questions!
What I seek is really quite ordinary: a general purpose tractor which has a tracked undercarriage instead of wheels. From what I can tell, since the beginning of the history of tractors there have been wheeled tractors as well as tracked ones. It would appear that crawlers were used on farms just as wheeled ones were. In the United States, that seems to have changed. Nowadays, as far as I can tell, there is only one crawler tractor that is manufactured with an American name on it: New Holland. All the rest of the farm tractors (general purpose) are wheeled. In Europe, however, crawler tractors are very popular. They are manufactured even today by Lamborghini, Deutz and possibly other companies. I have seen two Lamborghini crawlers advertised recently. One of them looks to be in magnificent shape. However, I cannot find parts for the machine. So, if it breaks down and I cannot find parts, I now will have a useless and expensive piece of junk. That is why I have turned my attention to John Deere. From what I can tell, I have the best chance of finding parts for an old John Deere than I do with the other older manufacturers, with the possible exception of Oliver.
Now, to further answer your question: why do I want a crawler when it would be so easy to find a wheeled tractor? I want a machine that has the best traction and produces the least compaction. I certainly dont need to tell YOU about the usefulness of a PTO and 3-point hitch. Where I live now Ive used it to power a bushhog, a post-hole digger and a a backup generator. Where Im going I expect to use it for a bushhog, post-hole digger and a water pump. I might also use it for a backup generator. Furthermore, there may be other tasks that can be powered by a PTO.
The loader will be used for a variety of tasks such as moving logs and snow.
I should also mention that I have no intention of doing any of the serious mechanical work on any machine. I would leave that to experts.
I hope that answers your question.
Thanks again!
