JD550 thru JD550G Serial Numbers

Post by Stan Disbrow » Wed Jan 30, 2008 1:54 pm

Here's the list of serial numbers, by year, for the JD550 through JD550G.

JD550 Straight

1976 238320 - 261195
1977 261196 - 287203
1978 287204 - 313963
1979 313964 - 340919
1980 340920 - 365417
1981 365418 - 377851
1982 377852 - 383414
1983 383415 - End

JD550B

1985 715315 - 723999
1986 724000 - 733274
1987 733275 - End

Note that the JD550 jumped from 'B' to 'G' here. I think Deere was trying to make things fit into a homogeneous group with the same variant letter, like Cat had been doing. ;)

Since the JD450 was up to 'G' at this point, so the 550 would be elevated up to 'G' as well. So, no 'C', 'D' or 'E' for the 550. Oh, and there was no 'F' for the either the 450 or 550. Who wants to buy an 'F' in anything????? :P

JD550G

1987 736382 - 742999
1988 743000 - 756489
1989 756480 - 767999
1990 768000 - 769556
1991 769557 - 775548
1992 776549 - 781381
1993 781382 - 795510
1994 795511 - 805302
1995 805303 - 815292
1996 815293 - 825661
1997 825662 - End

The source of the data is from a farm equipment quick reference guide that's intended to assist dealers in determining the year and current market value of trade-in equipment.

The guide as such only lists the beginning serial number for each year. I'm making the reasonable presumption that the last serial number for any given year is one less than the starting serial number for the successive year.

Thanks to Digitup for sharing the relevent pages from his guide with us so we can determine what year a given machine is.
