The first D21 Series II was produced May 19, 1965. Was following a thread on the red site discussing 1206 and D21. I see a few over there think the 1206 was the first ag tractor to be turboed. It may be the first over 100 HP turboed tractor if the first production 1206 was produced before May 19, 1965. The D19 was first produced in December 1961. Does anyone know what exact date the first production D19 diesel was built? BTW I have a soft spot for a 1206. Our neighbors have had one since I was a kid. They did snap the front axle off once. |
I got them thinking with that post didn't I ? The Nebraska test for the 1206 was from Sept. 8-23, 1965 and serial # 7502 was tested, I think (test report says # 502). 1206's started with # 7501. D21 series II were tested June 22-28, 1965. The test report says serial # 2109 was used but this has to be a misprint because Series II started at serial # 2201 (I would guess #2209 was tested). Sure looks like the D21 Series II would be the first over 100 Horsepower turbocharged rowcrop farm tractor.
I made this list up of different historic dates in Farm tractors (From the original post on the red power forum Here: http://www.redpowermagazine.com/forums/index.php?showtopic=65172 - http://www.redpowermagazine.com/forums/index.php?showtopic=65172 ):
