If you want a tiller, you need to go with the 2B. It was the one made for an 1812. If you're thinking about going to the rear PTO 3pt 48" tiller.... obviously you don't have the rear PTO. Plus, it's a load on the chassis for the SGT tractors with a longer frame and more weight out front. I don't know that you could even carry that tiller with a GT. Stick with what was made for the 1812.
