Ok! I get your point - but you will need a bigger capacity separating cylinder - for a world class 8 - 9 and 10 machine of the future. 500 - 600 bushel grain tanks - 12 to 24 row split corn heads - 40 - 60 foot split headers. 1. make combine 2 feet wider between the wheels 2. Put in the bigger feeder and cylinder You could go to hdrostatic cylinder drives and put in two transverse cylinders and a divided feeder housing. For simplicity - put in giant cylinder - still drive it hydrostatically. You must do something to make it possible to keep the transverse cylinder and still get drive power to it. best, bill koob
