[AJD] JD - Model "C"

[Paul O]

I am having trouble getting things on the list. I sent this out before and 
it came back. I am trying one more time.

My response to the interest in the Model C



For those interested in doing some research, J R Hobbs book on 'The John 
Deere Unstyled Letter Series" has a lot of good information on the entire GP 
Family of tractors.

Also, there is a small book about the Model C which was given along with the 
Model C toy at one of the early Two-Cylinder Expos.



Research which ultimately resulted in the GP began in 1925. There was a need 
for a smaller tractor than the D which could be used to plant and cultivate 
as well as till. The Model C eventually became the GP. Less than 100 
tractors were built in late 1927. There were many problems with the design. 
Many of these Model C tractors were recalled and rebuilt to a new 
specification adopted January 24, 1928. Production of the GP began later in 
1928 with serial number 200211.



Unless one is familiar with the GP, the differences between the C and the GP 
do not stand out. Perhaps the most obvious one is the seat. The seat on the 
C is supported by what appears to be simply a pipe standing on the platform 
instead of the flat steel springs on the GP. Another easy to spot feature of 
the C is the tool box position. On the C. the tool box is mounted on the 
transmission cover, on the GP it is next to the fender on the pulley side.



Here are a few more differences.

shows.

Thanks everyone for educating me on the JD model "C".
Would it be to much to ask if anyone has an emailable photo of one
of these (original) rare tractors ??  Or is there a web site where I could
down load a picture?
