It's a close one, but I'd have to say JD and Gleaner both did it about 83-84. But Gleaner might have had the edge before as I think they had the 27' header before they and JD had the 30'. To know when Deere had a 30' you'd need to know when the 8820 was introduced, as I don't think there are many without a 30'.
