"The
Evolution of the Tractor"
Showcasing
The development of the farm
tractor and how they evolved from the earliest forms using pioneering
gas and kerosene fueled motors.
"AN EDUCATIONAL
EXPERIENCE"
See examples of adaptations many of the early manufactures
used as they attempted to evolve from steam engine manufacturing to reliable
gas tractors and gas engine manufactures tried to prototype new designs
of the tractor.
Some
of the earliest manufactures tried to copy the concept of the horse drawn
equipment. Farmers were reluctant to change. Their horse drawn machinery
had seats which they sat on to drive the horses. The tractors were designed
around adapting to the horse drawn equipment.
The
new tractor was going to have to replace his old but reliable team of
horses. A tough change for many but necessary to prosper as increasing
demands had to be met.

Another early tractor dating pre 1915. Note the seat &
general similarity to a horse drawn implement. The motor and drive wheels
out front where the horses would have been.

Eventually design gave way to a rear platform for the farmer
to stand on. Considerable effort was required to steer these early tractors.
This one with the single front wheel was a feature intended to allow very
tight maneuvering on corners. A feature offered by the team of horses
but not many cumbersome early tractors.

Another example of an early model slowly giving way to
design improvements. Better steering contro,l but with transverse motor
(crossways). Transmission development was also in its infancy and a
cross motor design lends its self better to straight cut gears.

Below is an example of a huge 35-75hp Minneapolis tractor
built to service the western farm lands. Also utilizing the transverse
motor and large straight cut open gears, large wheels and chain steering
like its predecessor the steam traction engine. Many considered the
traction engine to still be superior and would never replaced by the
internal combustion gas engines. With there much more complicated, often
hard or imposible to start massisve gas engines, it was not unheard
of and comon to have to start one with a belt connected to another to
turn the motor over. Oil & Water would have to be drained in colder
weather and the oil brought inside to be kept warm for the next day
to assist in making the cranking to start easier. Not a good way to
start the day. There was no such thing as an electric starter yet.

Developments in design and modenization with electric
starters, simple designs and priced affordably made small tractor like
this Ford very popular. 3 point hitches and PTO's (power Take Off) to
drive machinery was eventually encorporated to almost every manufactures
designs.

Tractors such as this by the mid 1950's and on to 60's
were on every farm with PTO driven implements.
