The John Deere Company was and still is very interested in supplying
to the various end user any type of machine which will provide
revenue back into the coffers of it's manufacturing process. It's
called, "business sense".
One of the out of the way industries was potato farming of the
northeast and the northwest. Up to this time there were no adjustable
rear wheel tractors out there and apparently no one was even thinking
of it. However, in 1930, John Deere decided to build a special
model, with the proper fixed width rear wheel arrangement, just
for the potato farmers and the special width that their rows mandated.
The mainframe was the regular "GP"tricycle model which
had a 68" tread width and numbered, P5000 to P 5202.
The first 150 were special built as a "potato tractors",
with some differences hear and there on the tractor, but the remainder
was just the "GP" model with the different rear wheel
width. All were produced on steel.
The "potato tractor" was only produced for one one
half years and was dropped as a special design tractor. Needless
to say, if you can get your hands on one of these tator babies,
you got yourself a very rare piece of old iron.
After dropping the regular "GP" model as their 'Potato
tractor", John Deere made a set of wheel adaptors to fit
the advanced "GP", called the "GPWT". GP for
general purpose and the WT for wide tread. This tractor used the
flat head engine design (L head) and final drive reduction on
the rear axle just as the other 'potato tractors". However,
by now the newer "GPWT" tractors, as they were designated,
had over the hood steering design that would be retained until
the end of the age of the two cylinder, through the 20 series
Cultivators were available in two, four and six row variations
and were the put together on the tractor type with pipe through
the frame design.
