When the manual top link is adjusted so the skids are flat when the forks land, the forks will be tilting back towards the tractor when they are lifted. This can make unloading the forks difficult as the load basically has to be wiped off while driving away rather than tilted off. However, 3pt can generally lift more than front end loader so it is good for the occasional heavy lift despite being awkward. I have a 3pt set for my JD and use it on the rare occasion, like a real heavy log or stone that exceeds the capacity of my front loader, as I also have front forks on the loader.
Basically any tractor with a 3pt setup can lift forks. Just be advised it won't be the most convenient loading and unloading process. I sometimes have to crank the top link longer by hand with the load relieved to get the load off. Lumpy hilly terrain makes it that much harder.
