In cab adjustment for the shoe area has been on deere combines in Europe for years,its not that they copy,its the marketing side that keeps them out of the US.Any combine sold in Europe that doesn't have in cab shoe adjs,in cab chaff spreader fins,or things like a pop can cooler in cab wouldn't sell very good over there.In the US marketing people ask customers what they want,and usually after a while they get it,farmers didn't really want to pay another 1,200 to 3,000$ for a in cab shoe adjs tell now.
