Oliver OC-3 HG-31 crawler resurrected

I used this super-handy little 1950s Oliver crawler quite a bit in the 1990s for hauling logs out of the woods. Then I removed the magneto to get it rebuilt, and never got around to putting it back in again and timing it. So it has sat in our barn since then. AKA Cletrac HG-31 - track centers are 31" apart.
Since the 90s, I have used first a 35HP I-H B414 2WD tractor with a Norse 490 PTO winch and now a 60HP Kubota M5660 4WD with the same winch for logging.
I recently got motivated to get the old OC-3 running again, in order to sell it, so here it is in action. I don't know how much it weighs, but it's much lighter than my current tractor. But it's nice and small, and fits nicely into small spaces. It also has a lot of ground clearance, so it will go pretty much anywhere.
I just used it to drag out a couple trees I'd cut down so our solar panels weren't shaded during December sunrise. It was hard to get to the area where the trees were down, so this was perfect for squeezing into a tight area.

interesting little machine. Do they have dozer or loader attachments? I will have yo do a little searching,l. This, may just be what I have been looking for.

Yes, some have dozer blades and some have FELs.

@TheClampetts I live in Maine are they durable and easy to work on and more importantly, are parts readily available? If I decide to pursue this style of dozer, are there any version I should stay clear of and what price range would they fall into. Thank you for replying!
