I have been using the 1256 on the self powered tiller and tandem disc. Has about 75 lbs. of weight added up front so it would steer. Yesterday I put the tiller on the G16XT, sleeve hitch and electric winch to lift with. The XT handles the tiller better than the 1256 and steers great when tiller is lifted. Didn't realize there would be that much difference in front end weight between the two tractors. XL has a Briggs 16hp L head where the 1256 has the Wisconsin single in it.
