|steve wi said: (quoted from post at 23:10:35 07/02/13) according to a century of ford and new Holland farm equipment the first blue and gray from 1963-1965 were 6100's, as for the transmissions they were all select-o-speeds. although I saw a couple at an auction that they had installed truck 4 speeds but this was a while ago.|
I think that's the same as calling a 1965-1975 general purpose ag chassis 4000 a 4100, as it was referred to as a 4100 in some of the parts documentation and the first 3 digits of the stamped model number was "410" from 1965 to 1968 (changed to D10 in late '68), but it was always marketed as the 4000, and to confuse matters more they later made a model from 1976-1981 that was marketed with the 4100 name, at the same time that they marketed another model with the 4600 name. So is my 1973 general purpose ag chassis 4000 series tractor a 4000 or a 4100? I think that's the same with the 6000's, as the stamped model number started with 610 for the general purpose ag chassis models (and later 611), and 620 for the row crops.
