Im probably going to be buying an r62 in the next week, and most of our acres our swathed, but I am looking at some older cheaper corn and flex heads to go with it and was just curious what changes they made over the years, From what I can figure out, Is it 83 and newer that will fit an earlier r62?, and what year did did they change the hookup on the 2 series to the newer lateral tilt compatiable feeder house? Was that 94 when they came out with the 4/500 series heads, or was it after that???
