Aultman Taylor 30-60 1918
These were very popular tractors in road work and almost
every township in Iowa, Illinois and Indiana owned one at some
time. Many were sold for plowing and threshing. As with the 30-60,
the band wheel turned counter clockwise, thus requiring a straight
belt for threshing instead of the generally used crossed belt.
Twin City 1918
This model was continued until 1929, when Minneapolis
Co. merged with Moline Plow Co. and Minneapolis Threshing Machine
Co. to form Minneapolis Moline Power Implement Co. It was the
first company to use four valves in each cylinder for tractors.
Some autos have now returned to this system.

in existence that we know of. This company was organized in 1917
and went out of business in 1920.
COD Wheel Tractor Model B 1919
The significance of the initials COD has been lost, but
it was probably named for the three stockholders Conrad, Ogard
& Daniel. Few of these tractors remain. Belt pulleys ran off
the flywheel to operate the oil pump, fuel pump and water pump.
Avery 6 Cylinder Model C 1919
The Avery 6-cylinder tractor was a big success in practically
every kind of farm work. The Avery was advertised as a high grade
tractor at an attractive price, which included such accessories
as a platform, seat, tool box, draw bar and an air cleaner, equipment
that other small tractor makers charged extra for. Exhaust gases
were piped to the rear drive gears to clean and lubricate them.
All Work II Model F 1919
Electric Wheel Co. was acquired by Firestone Tire and
Rubber Co. This was a lightweight tractor with a big surplus
of power for general farming and orchard work. This tractor was
fueled by kerosene.
Moline Universal Model D 1920

solved the farm help problem of the day. A 1918 quote stated
"Operation of the Moline Universal is so easy that a woman
or a boy can handle it."
Huber Cross Motor 1920
This model turns very easy due to the large wheels in
the front. This tractor was a popular early model introduced
in 1917 and built until 1928.
Waterloo Boy Model N 1922
This tractor is the first model produced by Deere &
Co. It was also the first model to be tested in the Nebraska
Field tests in 1919. The Waterloo Engine Co. sold to the John
Deere Tractor Co. in March of 1918. Deere made this model until
1924.
Waterloo Separator 1925

were brought from the field and pitched in by hand. Grain was
put into sacks. The resulting straw was used in barns, or sometimes
as fuel.
Imperial Super Drive 1924
This is an Illinois Tractor Co. tractor which was sold
by the Robert Bell Engine and Thresher Co. in Canada under the
trade name of "Imperial Super-Drive".
Hart -Parr 18-36 Model H 1929

before the merger with Oliver Tractor Co. The Model H used a
3-speed transmission compared to the Model G which only used
a 2-speed transmission.
Oliver Hart-Parr Model 28-44 1930
Manufactured from 1930 to 1937, this tractor was one
of the first models made under the Oliver name. Oliver involved
farmers by having a color contest at State Fairs to vote on a
new model's official color combination. Meadow green with clover
trim was the winner.
Case 10-20 3 Wheel 1918
Looking at the design of this tractor, right hand turns
on a hill would be very dangerous!
Case Model 20-40 (with cab) 1918
Equipped with a two-cylinder engine, this tractor won
many honors at an early-day Winnipeg plowing contest for fuel
economy.
Case 9-18 Kerosene Model B 1918
A one piece main frame was used in this tractor to increase
strength and decrease weight. This tractor was known as the "Case
Baby".
Case 18-32 1920
The motor in this tractor was mounted crosswise. Three
to four 14" plows were recommended for use with this tractor.
The Case 18-32 tractor was extremely economical in its use of
fuel. More of the power developed by the engine is delivered
at the draw bar than in average tractors.
Case 12-20 1922
This tractor was a replacement for the old 10-20 three-wheeler.
Pressed steel wheels cut down on weight and lowered production
costs.
Case CO 1930
This tractor was a well accepted tractor in its time.
This tractor was mainly used in an almond orchard until the mid-1940s.

Some new engineering refinements advertised on this tractor
were redesigned track, an instantaneous oiling system where the
entire track could be oiled by pushing a plunger, and simplified
track layout.
Cletrac 30 HP 1929
This model was the largest tractor of the Cletrac line
in 1926 and was listed until 1930.
Cletrac Diesel 80 HP 1944
This tractor was a good logging tractor due to the design
of the transmission, which is pulling on both tracks at all times.
For turning, one track would turn at a faster rate than the other.
Most crawler tractors idled one track while the other kept moving
for turning.
Cummins Diesel (Old Smokey) 1944
This is a home made tractor built out of old surplus
tractor parts at a time when new tractors were unavailable. This
tractor was gifted to Fred Heidrick by the Phil Leiser family
and created by Earl Mallory.
Samson Sieve Grip Model S-25 1918
GM continued to manufacture this model after they bought
the company in 1917. It's unusual wheels made it possible to
grip in loose soils, such as that around Woodland, CA.
Samson Model M 1919
GMC tried to compete with Ford with this model for the
small tractor market. In 1915 General Motors Co. purchased Samson
Iron Works of Stockton, CA, making Samson a subsidiary of GMC.
Arthur Mason was the designer for the new tractor division.
Best "Humpback" 30 High Drive 1913
This is the only one known to exist. It was the forerunner
of the orchard tractor, but if used in orchards it would not
have had a top. It used a drive gear above the independent idler
wheels. This lowered the tractor by about 12 inches. It was considered
one of the most popular Best models.
C. L. Best 75 1914
This model by C. L. Best Co. is one of Best's largest
tractors. The Best 75 was one of the first tracklayers to utilize
a power steering device with cut steel gears enclosed and run
in oil. The Best 75 also featured the famous "frictionless
rocker joint".

wheel. The term "Muley" was a farmers term likening
a tractor without front wheels to a cow without horns.
Holt 120HP 1917
The Holt 120 was built for the the military in WWI to
tow artillery. Only 800 were built. This particular tactor was
half way to France when the war ended. It was unloaded onto the
dock in France. Two years later a US buyer bought it and shipped
it back to Los Angeles. It was used until WWII then abandoned.
It is the only one of its kind left in the world, that we know
of.
Holt Military 10 Ton 1917
These tractors were not sold to the general public until
after the war. The high mortality rate for horses during WWI
is one reason why these tractors were starting sent into battle.
Holt 5 Ton "Caterpillar" 1918
In addition to general farming, this model was used to
move artillery across shell torn battle fields as well as long
stretches of stone roads in France.
Holt Self-Propelled 16' Wood Harvester 1918

from 1931 to 1933. Wide tracks designed for hills and swamp land
served as the base for working in wet or soft soil.
Caterpillar 28 Orchard 1934
Manufactured in 1934-35 only. The low seat indicates
use for orchards.
Caterpillar R-5 Dozer 1936
Very few of these tractors were made and sold because

Lindeman brothers in Yakima, Washington. They mounted these units
on crawler tracks. Deere entered crawler production with a model
after this one.
Wallis Model 15-27 1923
Massey Harris purchased JI Case Plow Works in 1928. The
most significant engineering feature was the U frame. A heavy
steel plate enclosed and supported the engine, transmission and
final drive. It sealed moving parts from dust and supported the
mass without additional frame.
Bean Spray Rig 1925
This spray rig sprayed 6 gallons per minute at 250 lbs
of pressure. It was used primarily for sulfur and insecticides
in orchards and vineyards to control insects. The bean sprayer's
porcelain lined cylinders would not corrode. It is powered by
a two horsepower Witte engine.
International Mogul 1910
This International model features a rare friction drive,
instead of cog-wheel to reverse, but a conventional clutch for
forward. This tractor was simply a one cylinder engine mounted
on wheels, which only produced one horsepower at the draw bar.
International Slant Hood Model 8-16 1921

Advance- Rumley acquired rights and patents to the Toro
convertible tractor-cultivator and this tractor appeared.
Fordson Model F 1919
This is one of the first tractors Fred Heidrick restored.
Henry Ford couldn't use "Ford Tractor" because there
was already a Ford Tractor Co. in 1916, so the Fordson trademark
was adopted. Each Fordson came with a canvas cover, to protect
the wooden steering wheel and the wood induction coils.
Fordson Track Hadfield-Cahl Tracks 1923
"Cahl" advertised their tracks for the extra
pull. They made a track type tractor of the Fordson.
Fordson 10-20 1924
The fenders on this model were added extra in 1924. All
Fordsons came with a canvas cover. Farmers would often be in
a hurry to finish the day and would throw the cover over a hot
tractor and set it on fire.
Fordson-Towner Locomotor 1924
This Towner attachment pulled three to four ore cars
in mines around Placerville. CA. This attachment sold for $750.
H. F. Towner was better known for his tillage tool business.
Fordson Snowmobile 1926
This was known as an Armstead Snow-motor. Hauling capacity
was said to be five tons. Each drum receives power from a separate
clutch which, depending on the position of the steering gear,
engages and disengages. It can also traverse bare ground. This
machine hauled mail from Truckee to North Lake Tahoe.

had to furnish. It was advertised as a practical, low priced
motor cultivator.
Homemade Swather 1935
This swather was made by Fred and Joe Heidrick from junkyard
scrap consisting of 2 long channel irons, Model T Ford differential
and a STAR 4 cylinder motor attached to a 10 foot Caterpillar
harvester header. This swatcher was used to open fields and for
going around the outside perimeter of a field so a larger harvester
could complete the harvest.
National 25 1930
This tractor had a very short production history due
to patents pending by Caterpillar Tractor Co. It was advertised
as having extremely high clearance which was important when the
tractor was used for plowing deep or working rocky or rough ground.
Allis Chalmers Monarch Neverslip 30-18 N 1918
This was the largest of the early Monarch tractors. This
model, with modifications, was produced until 1924, when it was
replaced by an entirely new crawler tractor line. It had the
motor in the rear and transmission in the front.
Allis Chalmers Wheel Model 20-35 1924
Pin striping, swivel seat and axle hub covers were extra
cost options on this tractor. Allis Chalmers introduced its air
washer with this model. An air intake pipe fed through a cast
iron water bath.
Allis Chalmers Model 75 1928
The lighter Model L succeeded this heavyweight in 1932,
with more power and less weight. A heavy steel plate protected
the radiator, which would have been important when used in logging.
Allis Chalmers Model 50 1929
Allis Chalmers purchased the Monarch Tractor Co. plant
and assets in 1928. At this time, Allis Chalmers crawlers were
basically a Monarch design, but within a few years a new series
of Allis Chlamers would emerge.
Allis Chalmers Model L 1932
This model offered five forward speeds, ranging from
one to six MPH. It replaced the heavier Allis Chalmers Monarch
75. The Model L was built to meet the demand for a powerful,
heavy duty, easily handled machine.
Allis Chalmers Model 35-K 1933
This tractor belonged to Helen Heidrick's father, Lloyd
James, and has been in the family for 60 years. The Heidrick
brothers owned the same type of tractor at the same time.
Allis Chalmers Model K Diesel 1935
This is the first Allis Chalmers model to use the Hesselman
Diesel Motor. This motor did not produce very satisfactory performance
results
Allis Chalmers Model S 1936
This model became the "SO" model with the addition
of the diesel engine. Eventually, it became the Allis Chalmers
HD10. This tractor was used primarily for rice farming in Northern
California.
Allis Chalmers Model M
Many Model M crawlers were used by the military during WWII
for building roads, carving airstrips out of the jungle, or clearing
the way for transport vehicles.
Yuba Ball Tread 15-25 1920
The ball bearing track system made the Yuba unique. This
tractor was manufactured in Marysville in Northern California.
Farmers used to pay youngsters for finding ball bearings which
had fallen out of the tracks as wear made them loose. They kept
a can of larger ball bearings to take up the slack.
Yuba Ball Tread 25-40 1921
This tractor was manufactured in Benicia in Northern
California. This type of track eliminated track rollers.
