back in the early 80's I built pto winches for tractors from the 16hp beaver to the 33hp yanmar and everything in between. I built an 8000lb unit and also a 12000lb. They had a blade on the back for pushing and clearing brush and a fairlead to keep the line on the drum as well as a surrounding flange that would keep the line from coming over the flange on the winch and wrapping up on the drum axle. With pto winches be sure that you have a left hand rutn on the input shaft to make the line spool over the top when coming in. On winches that are upright models, the line must come in on the bottom of the winch. I have them scattered from oregon to alaska without any complaints and have thought about getting back into fabrication of them.
In my opinion the pto is the way to go as the hyd will not give much line speed, although it is a safer winch as you can set the relief valve on the hyd spool delegated to the winch to prevent line breakage.
As to the finn and austrian winches, they are nice, but, with the line being pulled in from so high initially, they are hard on the lower links of your tractor. As the line pulls it pulls bak on the top ling trying to compress the bottom link as the tractor is pulled bakcwards. I have seen some of the smaller units with factory angled lower links collapsed by the winch.
I do have a winch permanently mounted in my loader, which is hyd and I use it more that I can tell you, I think anyone other than the lightest of hobbists should consider one. I also have a pto unit that I use for logging off the 3pt that I made. It is a used model 9 gearmatic from a log skidder and I can outlog my 350JD crawler with it.
Here is a pic of them both. Note the lack of a good fairlead on the front winch, I would recommend one, I just need to get in gear and make it.
