The Farmall was the name of a make of tractor and later a brand name
for tractors manufactured by International
Harvester. The original Farmall was the first general purpose tractor with narrowly spaced
front wheels. The narrow front combined with good ground clearance allowed for
more nimble and accurate field cultivation,
yet the Farmall could perform all the other duties a farmer would have
previously achieved using a team of horses.
In time, other tractor manufacturers introduced models with a similar form
factor (Shape) as the Farmall. As a class, these are generally referred to as
row crop tractors.
In 2011 the Farmall brand was reintroduced to the market ona line of smaller
models in Europe.
Models
Farmall and the F-series
The first row crop tractor manufactured
by IH was given the name Farmall. Development began around the start of
the 1920s, and the tractor was introduced in 1924. IH was fearful that this new
"tricycle" type of tractor may not sell well, so when the tractors rolled out,
they were meant to be sold only in Texas, as to minimize potential embarrassment
if not successful.
The Farmall name became so famous that it came to be treated as a brand name.
Originally, however, Farmall was a model or type name of McCormick-Deering.
In 1932 IH introduced an updated Farmall, which received the designation Farmall
F-20. The F-20 replaced the original Farmall, which became known by the
Retronym Regular (after the introduction of the F-20). IH also added
other new tractors to the series which became known as the "F-series". These
included the Farmall
F-30 (1931), the Farmall
F-12 (1932), and the Farmall
F-14 (1938). All Farmall tractors were painted battleship grey until
November 1, 1936, when a switch to red was made.
Letter series
The F-series tractors lasted until 1938. In 1939, the "letter series" of
tractors was introduced (A, B, BN, C, H, and M; another smaller tractor, the
Cub). IH commissioned industrial designer Raymond
Loewy gave the tractors a new, sleek look. The letter series offered a
wider variety of options and power.
The tractors were updated to the "super" series in 1952 (with the exception
of the A, which became a "super" in 1947, and the B and BN, which were
discontinued in 1948) and received many improvements. Many of these tractors
(especially the two largest: the H and M models) are still in operation on farms
today. The letter series of tractors was produced until 1954, and was a defining
product line in IH history.
Letters to
numbers
For 1955 model IH tractors, the numbered "hundred-series" were offered. The
"100" series models were given slightly different looks and few new features,
but were essentially the famed "letter series" tractors. In 1957, IH again gave
the tractor lineup an overhaul. Although the tractor design wasn't changed, new
white paint was added to the grill and sides and new number designations were
given. This improved sales at the time, but IH's inability to change and update
was already showing.
At the Hinsdale, Illinois Testing Farm in July 1958, IH entertained over
12,000 dealers from over 25 countries. IH showed off their new "60" series of
tractors: including the big, first of their kind, six-cylinder 460 and 560
tractors. But the joy of the new line of tractors was short lived. In June of
that year, IH recalled the 460, 560, and 660 tractors: their final drive
components had repeatably failed in production models. IH, who wanted to be the
first big-power manufacturer, had failed to substantially update the final
drives on the new six-cylinder tractors. These final drives, which were
essentially made up of unchanged model "M" components, would fail rapidly under
the stress of the more powerful 60-series tractors. IH's competitors took
advantage of the recall, and IH would lose customers in the ensuing months.
Throughout the 1960s IH would introduce new tractors, and new methods of
selling them. As producing tractors was the lifeblood of the company, IH would
have to remain competitive in this field. They both succeeded and failed at this
goal.
Standard, industrial, utility and other special purpose
models
Many Farmall tractor models have one or more mechanically similar models
under another IH brand designed for other uses, such as industrial, utility,
orchard or wheatland use. These models have lower ground clearance and a wide
front axle. During the letter series era, these alternate models were under the
McCormick-Deering brand, later models were under the International brand. Some
examples of similar models:
Farmall H -- McCormick-Deering
W-4 Standard -- McCormick-Deering
I-4 Industrial
Farmall
300 -- International
300 Utility
Farmall
450 -- International
W-450 Wheatland
Farmall
656 -- International
656 Row-Crop -- International
656 Utility
The International 656 Row-Crop was a bit of an anomaly until IH dropped the
Farmall brand, in that it combined some of the customary features of a Farmall
(such as an adjustable wheel width) with a utility tractor.
End of an era
1973 would see some important events for IH. On February 1, 1974 at 9 A.M.,
the 5 millionth tractor came off the assembly line at the Farmall Plant
in Illinois. IH was the first tractor manufacturer to accomplish this.
Finally in 1973, IH officially dropped the Farmall name from its new tractor
offerings after this date. This ended an era that began with the first Farmall
Regular back in 1924. However, Farmall tags still appeared on some 1974
and 1975 tractors until the factories exhausted their stock of tags made before
1973.
In 2011 the Farmall brand name was reintroduced on some models for the
European market.
Model list and
power ratings
Generally tractors were marketed by the number of 16" width plows (plough UK)
they could pull in average soil to indicate their power.
Here is a list of all Farmall tractors produced for North America:
1-plow: (12" width or less) Farmall Cub ,
Farmall A,
Farmall Super A,
Farmall B,
Farmall BN,
Farmall 100,
Farmall 130,

2-plow (14"):
Farmall F-12,
Farmall F-14,

Farmall 1456,
Farmall 1466,
Farmall 1468,
Farmall 1566,
Farmall 1568.
Note: Depending on the plough width used, a three-plough tractor could
handle a four- or five-bottom plough. For example, in the 1950s and 60s it was
very popular to upgrade the Super
M-TA and 400
model 264 cid
engine to 281 cid version. An economical cylinder sleeve and piston change
was all that was needed. This brought the power level up to that of the 450
model. Above are general ploughing abilities. These plow ratings are
generalizations dependent on soil conditions but were advertised as such.
There were also some Farmall models unique to the European market:
Farmall
DF-25 (comparable to the H),
Farmall
DGD4 (comparable to the Super H),
Farmall BMD (British MD)
and
Farmall
B-450 (British 450),
These models had a direct start diesel engines rather than gasoline start
system of their American counterpart.
Production
information
The Farmall Cub,A, B, 100,
130, and 140 models had the seat
offset from the engine, allowing the operator to look directly at the ground
under the tractor. This feature was called Culti-Vision because it was
created to give the operator an excellent view of the cultivator teeth as they
cultivated the vegetable row. (Cultivating in this context refers to
breaking up the soil next to the vegetable row, which kills weeds by uprooting
them and/or burying their leaves).
IH "Red" became the standard tractor color after 1936 through the 1970s. The
only variations known from the factory were Highway
Yellow, used for municipal and Demonstrator White, used in the 1950s or
Gold, exclusively in 1970, used for dealership demonstrator models. Tractors
with other colors have been known to exist outside of the official colors. Most
likely these were painted by the dealer at owner request, or painted by their
owners.
The first Farmall tractor with an optional diesel
engine was the M.
It started on gasoline and was manually switched to diesel after warming up. The
Super
MD, 400,
and 450
diesels used the same engine design as the M but with larger displacement (more
cubic
inches). The next Farmall tractor to offer diesel power was the 350.
Unlike other diesel engines that IH manufactured itself, the 350 engine was
built by Continental
Motors. It was IH's first 'self-start' diesel tractor (no gasoline). IH then
developed their own new self-start diesel engines for the 460 and 560
tractors.
The Torque
Amplifier (TA), first introduced on the Super M in 1954, was an extra
low-range gear ratio (comparable to the two-speed rear of a truck) that allowed
for a quick downshift without the clutch to gain torque
at the drive wheels. The TA model was then called Super M-TA. The TA became an
option on the model 300 and larger tractors after 1955.
The Fast
Hitch was IH's answer to the Ferguson System (three-point
hitch) developed years earlier by Harry
Ferguson. The Fast Hitch was first offered as an option on the Super C. Fast Hitch
was then an option on the 100, 200, 300, and 400 and some later models. However,
even the Fast Hitch had three incompatible variants (100—single prong, 200—two
small prongs, 300/400—two large prongs). IH discontinued the Fast Hitch in the
1960s after the three-point
hitch was standardized by the industry. There are kits available from a
variety of sources that will either convert a Fast Hitch to a three-point, or
add a three-point hitch to tractors that originally only had a fixed drawbar.
International Harvester was one of the earliest manufacturers to provide a
stepless transmission in a row crop tractor. Introduced first as an option on Farmall
656 and 544
tractors, the hydrostatic
transmission would become a defining feature of the Farmall
70 Hydro and Farmall
100 Hydro models. Note some models were marketed under the IH brand or
International in the UK
Production facts
From 1924 until 1963, Farmalls were the largest selling row crop
tractors.
The Farmall H, produced from
1939 to 1952, became the top selling individual tractor model of all time in
North America with over 390,000 sold.
The Farmall
Cub (later re-named International Cub) remained in production the longest
from 1947 until 1979 with very minor updates in engineering & design.
The Farmall
Culti-Vision feature remained in production the longest from 1939 - 1979.
A few clever mechanics have created so called Super H-TA (Super H with
Torque Amplifier), Super HD (Super H Diesel) and F-16 tractors. IH never
manufactured such models.
The Farmall Works plant at Rock Island, Illinois opened in 1926. The last
tractor was built on May 14, 1985.
International's Ag division was sold to Tenneco
in 1984.
Case
IH has revived the Farmall brand on some of their latest tractors.
The Farmall
Hydro 1066 had less drawbar power than the gear-drive Farmall
1066, leading to the creation of the Farmall
Hydro 100.
