Does your stiener have the 3pt hitch?. Some do, some dont. My 430max does. with the 3pt hitch, it would just be a matter of building a small box or tray to hook to the hitch. set it off/on when needed. I have never been a fan of the diverter valve Stiener used to change the fluid from the front hitch to the back hitch, they should have used a seperate vavle so you could use either the front attachment or the rear, the way it is now, you either run the front, or you run the rear and I found that aggravating when ever I tried. Never built a carrier for my machine, instead I bought a Ventrac and the Stiener is now just rusting away. I should just sale it, it only has about 400hrs on it and hasnt been out of the shed in several years.
