I have a 2305, when new (2010) I took the mower deck off and used a box blade, put the mower deck back on and tractor wouldn't lift the deck. Figured out it was missing the travel bar that came with the tractor. I welded a 2 inch by 6 inch plate on the arm on the left rear 3 point hitch. Now the deck will lift with or without any attachment installed. Thought someone might like the idea. Pic attached.
