I do not know about a 2144 but comparing a 1640 to a 1660 , where the main axle joins the frame of the thresher is a lot weaker. If you add the extra weight and fall in a dith you are going to have problems. I bought a used 1640 already with the standard bin extensions that go to the top of the cab. The previous owner had already beefed up the frame before he had any damage. So I assume he was aware of the frame problems.
