JD400G Serial Numbers

Post by Stan Disbrow » Fri Feb 01, 2008 12:21 pm

The JD400G was an 'economy' crawler dozer made to boost sales. Don't confuse it with the JD400 industrial tractor of the 1960's, which was the industrial variant of the 2010.

Don't you hate it when they reuse model numbers like that? I remember a comic conversation with a JD parts guy when the '420' lawn & garden tractor came out - he kept insisting that the part in his hand was correct, and I kept saying no, not the L&G tractor the older 420 crawler! :P

Anyway, onto the serial numbers for the JD400G crawler.

1988 742614 - 747920
1989 747921 - 764403
1990 763404 - 771695
1991 771696 - 778725
1992 778726 - 787254
1993 787255 - 795279
1994 795280 - ?

This was made from 88-97, but the list I have only goes up to 1994.

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.

I had the same thing happen with the Model 50 backhoe- the newer one is much smaller than the full-size backhoe of the '60s. I couldn't convince the sales guy of that but the parts guy was a little more informed.

Anyhow thanks for posting up all of the serial numbers for these different models. That will come in handy for a lot of us.
(1) JD Straight 450 crawler dozer with manual outside blade; (2) JD 2010 diesel crawler loaders; (1) JD 2010 diesel dozer with hydraulic 6-way blade; (2) Model 50 backhoe attachments, misc. other construction equipment

Hi,

My pleasure. I was wanting some of this data myself as I look at every 350 and 450 I see with a 'for sale' sign on it! :P
