Looking at 7230 with no chopper. Stopped in at my local case dealer to find out if there is a kit a person can install, couldn't find anything. One of their 30 year veteran mechanics happened by, asked him if he has ever installed one, nope and didn't think anyone at the dealership had ever installed one. Maybe this is a deal breaker? Any after market ones? How much labor to install? Then need processor behind it ( think that's what it's called) to spread straw. Maybe just find a machine with the equipment I need? Found a thread that was talking that choppers actually slow productivity of the machine, to close to rotor and can't feed it through fast enough. Producer was talking about bolting a New Holland chopper on back and that Case is working on a external one?
