I've been working on building one for my 2,7 tonn Terex, have the rotor done works great,
But I got my hands on an used an broken engcon so now I'm planing to fix it and use that one instead, but will probably finish the homemade one since I have all the parts for it.
Here in Norway all machines have an tiltrotator, not so many of the small ones, the weight is the biggest issue with the small ones, you loose a lot of power tilt an tiltrotator on.
