Here's a pic of a similar model, the TU160. (Buck Bond, I'm referencing one of your pics...hope you don't mind!)
So, looking at this, it looks like there might be a few different options, all of which you'd probably have to do some of the fabrication yourself or have it done custom. There's obviously not enough room to get the loader frame between the front wheels and the platform, so here's some thoughts.
1) Probably the simplest option would be to have the loader frame wider than the tractor. The mounting brackets would have to extend out past the front wheels, making the tractor wider.
2) Would it be possible to somehow widen the wheels with some sort of hub extender or something? That might allow you to get a loader frame between the front wheels and the body. On the downside, that might make turning really difficult, and might put considerable stress on the front axle.
3) How about mounting the loader frame in front of the front wheels? I know this is quite unconventional, and would probably require mostly custom fabrication, but looking at my old Power-trac, the loader arms are attached to the front of the machine. This has the advantage that you can have two parallel arms (looking at it from the side), so you get a mechanically self-leveling loader. This would put more weight on the front axle though (full weight of the loader plus any load, vs. half the weight of the loader plus load for a conventional mid-mount). You might end up with quite limited lift height because the lift arms would have to be quite short. Thoughts on this?
4) Here's a completely radical thought. How about mounting the loader posts behind the rear wheels? Most skid steer machines actually lift from the back. You'd end up with probably considerable lift height because the booms would be quite long. This is an interesting thought to me. You'd have to do it so that it doesn't block ingress/egress of the tractor, so the booms would have to be either quite low or quite high (either step over them or crawl under them). This is an interesting thought. This puts most of the weight of the loader itself on the rear axle.
Enjoy my musings!
