6620 Green Cabs

[JMiles]

What years did John Deere go from making 6620 Combines with Yellow Top cabs to Green Top cabs?

I've had people tell me 1983, and some say 1984 but I would appreciate all the input you can give.

The 6620,7720, and 8820 combines went to the green cab roof in 1985. These would be referred to as the Titan II models.

The 1983 and 1984 models actually had a couple changes from prior years, but still had the yellow cab tops. The most noticeable change would the the addition of a two speed, hi and lo range cylinder drive.
