I have the GTX2100, same model basically. Just the previous version.
The transaxle on it is a Hydro-Gear BDU10. I had contacted them about the transaxle and if they would recommend ground engaged implements. They took the stance you have to contact the tractor manufacturer because they only supply the one item. So they wouldn’t answer directly either.
I did see this video on YouTube of a guy plowing with the XT3:

The tractor makes it look easy.
