First, It isn't my machines. Second, if a customer want to buy something, you sell it to him or he buys it somewhere else. Third customers are well aware of what a larger hopper can possibly do to a machine, they are not dumb. Fourth, in our area, we have never had any kind of a failure of frames, rims, or final drives from hopper extensions on newer machines. Actually have seen more final drive and rim problems on older 9600 with factory extensions. Your area and conditions are probably different than ours. last, most customer will request an extension on the machine, although a few do request a machine without one. Have a great day!
