History Of Allis-Chalmers

The history of the former tractor manufacturer Allis-Chalmers dates back to 1847.  However, it entered the 1950s lagging behind the leaders Massey-Harris, John Deere and International Harvester.  Throughout the 1950's and 1960's the company worked hard to keep up in the battle for market share and horsepower dominance.    

Model "U."  Allis-Chalmers' Model U first began to be produced in 1929 as part of a partnership with United Tractor Company to compete with the Ford Fordson tractor.  It sold well enough to remain in the Allis-Chalmers' product line until 1952.  The tractor generated up to 30 HP, especially later on its production run and weighed 4,000 pounds.  The "U" was also the first farm tractor from Allis-Chalmers to come equipped with rubber low-pressure tires.

Model "B." Produced from 1937-1957, the Model "B" was revolutionary for many small farmers. It was the very first "modern" tractor with a price tag of less than $500 - with rubber tires at a time when a set of rubber tires could increase the price of a tractor by $150.

Model "G." The smallest A-C tractor was not the "B."  In 1948, an odd-looking machine called the "G" was introduced. It came with slightly over nine horsepower and was unique in the fact that its four-cylinder engine was located in the back of the tractor and its tubular curved frame made it possible to mount implements on the front. Between 1948-1955 around 30,000 of these tractors were sold.  

The "WD."  In 1948 production of the "WC" came to an end and was succeeded by the "WD." This new model had a similar appearance to its predecessor, however, the "WD" also had so many improvements and new features that the sales team needed to learn an entirely new set of terms for this tractor. The new features included power-shift wheels, traction-booster, single hitch-point implements and two-clutch power control.  The 24 to 30 horsepower of the WD enabled it to pull as many as three plows.  The "WD" was produced for six years and sold more than 145,000 units during this time.       

The "WD45."  By 1952, International Harvester and John Deere were introducing tractors with more than 40 horsepower, meaning that Allis-Chalmers needed to have a response. The company introduced the "WD45" that came with 30 to 39 HP at the drawbar.  This tractor with its increased power brought it into four-plow class and it sold quite well.  This new "Snap-Coupler" hitch system enabled the farmer to back up over his implement until the tongue snapped to the hitch. For several years the three-point hitch was unable to do this.  In addition, the WD45 was the first tractor from Allis-Chalmers that offered power steering and a diesel engine.  

The "CA."  The Model "B" was getting close to the end of its production run by 1950, and more modern tractors within the 20 HP range were being offered by competitors, such as the IH "Super C" and John Deere "M."  In 1950 Allis-Chalmers introduced its Model "CA."  It had a four-speed transmission, the "WD's" two-clutch system and power shift wheels.     

First "D" series.  The "D14" and "D17" were introduced in 1957 and featured an improved ride for the operator, new styling, larger diesel engines and more power to the Allis-Chalmers line of tractors.  The "D14" come with 30 HP and was manufactured until 1960. There were four "Series" upgrades for the "D17" from 1957 through 1967 and it produced 46 to 49 HP.  Both of these models introduced a new position for the tractor's operator.  It was located in front of the machine's rear wheels.                

Models "D10" and "D12." Allis-Chalmers introduced these two models in 1959 to fill the lower end of its lineup. They both came with 24 HP.  The width between the tires was the only difference between these two models.  The D12 was able to cultivate wider rows.  These models were quite successful and underwent three series updates. The tractors produced 30 HP by the end of their production run in 1968.  Customers demanded diesel engines by the late 1960's, but Allis-Chalmers was unable to produce one at the right price point.  

The "D15."  The "D14" was replaced by the "D15" in 1960 in the 33 to 38 HP range.  This tractor produced around 18 percent more power and featured a larger four-cylinder engine.

The "D19."  Higher horsepower was being offered by other manufacturers by 1961 compared to Allis-Chalmers, with 50, 60 and 70 HP models becoming quite common.  Allis-Chambers introduced its Model "D19" with 58 HP.  The extra power was achieved by providing its diesel engine with a turbocharger system. It was the first model included a turbocharger that was factory installed and part of its standard equipment.  The tractor produced 64 HP by the time its run ended in 1964.     

The "D21."  This was the first model from Allis-Chalmers to break through the 100 HP barrier, with 93 HP horses on the drawbar and 103 on the PTO.  It was sufficient power for pulling a seven-bottom plow which allowed the tractor to drive on level ground rather than needing to have one set of its wheels placed in the prior furrow.   

The "Hundred Series."  Allis-Chalmers in 1964 started to sell the "One-Ninety", which turned into its new model line.  Until 1971 its model numbers were spelled out for some reason.  The line was distinguished by its refinements to its implement hitch system, transmission, and operator along with its new squared-off styling.    

"Two-Twenty Landhandler."  Changes to best practices and agricultural technology by 1969 called into question the concept that it was always best to have more horsepower. Conservation tilling techniques resulted in large plow units being used by fewer farmers. At this point, large combine harvesters had become self-propelled instead of being pulled by a tractor.  Also, not a lot of power was required by the remaining farm chores.  Therefore efficiency was emphasized by Allis-Chalmers as well as other manufacturers - which involved the ability for pulling the same implement more quickly instead of increasingly larger implements.  The "Two-Twenty Landhandler" model that was introduced in 1969 had the identical 117 horsepower that the "D21 Series II" did.  However, it had a heavier rear end for handling heavier pulls and beefed up the transmission.

The A-C Persian Orange machines by 1970 were well respected and Allis-Chalmers was poised to capitalize on the decade's booming machinery market.  However, the company did not survive the 1980's recession.

Allis Chalmers C

Built between 1940 and 1950, Allis Chalmers Model C has a total of 84,030 in production. The AC Model C had many options that included 600 RPM PTO Assembly as well as hydraulic lift assembly. It also offered both front and rear weights as well as a swinging drawbar. The Model C tractor also had an option of an adjustable wide front axle and there were 5149 of them built. It had a single front wheel and there were 664 of those built. It was a two plow version of the Model B that came standardized with a tricycle front axle and dual front wheels. The standard features on the AC Model also included two plow capacity as well as rubberized tires that offered rear fenders and a narrow front axle that had dual front wheels and a six-volt electric starter that included lights. You could replace the fenders as well as the light and can still do so today at the Allis Chalmers C parts here.

Allis Chalmers HD6

The HD6 Allis Chalmers model tractor was for light industrial farm uses. It was manufactured between 1955 and 1965 in the Springfield, IL factory. As a diesel powered farm tractor, it offered a variety of specs that gave it a position of importance on any farm. It is durable and still in use today on many farms.


The tractor engine is what determines how much of the land can be farmed. HD6 was designed and equipped with Allis Chalmers vertical I-head engine and offers a 4 cylinder as well as a displacement of 355 ci. With 5.6 liters this engine had to have 15 quarts of coolant and was to be run on diesel fuel. It had a 37-gallon tank for the fuel. It required a 24-volt starter and was powered by 2-24 volt batteries. It had a compression ratio of none other than 15.25:1. The engines were both rated to 1800 RPMs and each had a bore as well as a stroke of 4.4375 and of 5.5626.


Built for heavy-duty work on the farm, the Allis Chalmers tractor is 66 inches tall and 127 inches long. Ideal for larger sized farms. It weighs in at approximately 13,400 pounds.

Serial Number Location

Just as with many tractors, serial numbers of the HD6 are located on the housing or the instrument panel. They are then repeated on steering clutch in the housing panel as well if the number is scratched or rubbed off you can find them in these other locations.


Claiming to support drawbar power, these are up to 39 horsepower and belt power on the 54 horsepower. There may be even more power when tested them they found the drawbar to have a 50 horsepower on and the belt showed 60.5.


Equipped with a manual transmission so that it will have a higher degree of maneuverability depending on the changes in the terrain. It has 5 speeds forward and one reverse speed. It also has a crawler chassis.

Allis Chalmers Garden Tractor Parts

In the 1950s, the U.S. was becoming more suburbanized and there was a sudden need for riding lawn mowers. Major farm equipment manufacturers were wanting to expand into this market to improve sales. International Harvester and John Deere both designed and built all of their own equipment. Other chose to buy from firms that had an existing product line and reassign the label as their own in order to maintain equals with the competition in the market. Allis Chalmers would go with Simplicity Manufacturing in the year 1961, Allis Chalmers garden tractors became available with 7.25 in horsepower. The B-1 was born. It had a few changes with the decals, paint and some of the sheet metal. It was exactly identical to the Simplicity 725. By 1963, the B-1 was replaced by a 9 horsepower B-10. By 1965, this was to become a Big-10 and had a 10 horsepower engine. In 1966 it reverted back to the B-10 when they introduced the B-12. Until 1971, Allis Chalmers garden tractors were all painted yellow and powered by a Briggs and Stratton engine.

In 1965 Simplicity was purchased by Allis Chalmers. The government challenged their purchase. With fair trade laws in effect, the government believed that they had too much of a share in the market and they chose to limit the competition. Thus, by 1967, Allis Chalmers opened up a newer plant in Lexington South Carolina to exclusively build garden tractors. The first garden tractors built there were the B-297 and the B-110 as well as the B-112 and the HB-112. In 1970 more models were introduced including HB-212, B-212, B-210 and B-208.

In Port Washington, Simplicity tractors continued to be built. However, there were minor differences in the paint and the decals. By 1971 the series 300 had introduced many unique design changes. Painted orange and with the hoods painted in cream, they had a Kohler engine. They bore little if any resemblance to the originally built Port Washington Simplicity models. Mower decks were now different and in 1971 the B-207 and the B-208 updated their paint scheme to the cream and orange colors. AS they continued growing the line they introduced more models and soon had a 20 horsepower engine. By 1975 the 620 offered up more competition and the list went on as they continued updating their tractors to remain in competition with the other brands. As far as we can tell, the 620 and the 720 ar identical other than the later 720s had upgraded front axles. Later, Allis Chalmers came out with a secondary model of the 616 that was painted over the Simplicity 4216 and with no relation whatsoever to the Powermax 616 of earlier models.

With Nixon now in office, most of the fair trade laws would be repealed. In 1973 Allis Chalmers decided to close the Lexington plant and they then transferred al lof the production back to their Port Washington location. Here, the Allis-Chalmers and the Simplicity Garden would again become identical other than the paint and the decals which were uniquely Allis Chalmers. While many of the models didn't have an exact counterpart with Simplicity, many of them did.

In 1974 a new 700 series were introduced to the market and their all orange color scheme matched the larger farm sized tractors. Most of them had Kohler engines however, there were a few of the Briggs left. The newer 600 series of lawn tractors were revealed in 1976. with the 600 and the 800 added in during the Briggs engines. In 1979, the 900 series would replace the 700 series and only Kohler engines were used by this point. There were a few Briggs made to order at this time.

Allis Chalmers WD Starter

When the WC ended in 1948, the WD would be the successor. Newer models looked similar however, there were new and improved features on the WD. The sales force would have to learn new terms and information about the tractors at this time. With a two-clutch power control, they offered a single hitch point as well as implements. They had a traction booster and the power shift wheels would offer new features. With a two clutch allowing operators to stop drive wheels while power would continue operating the implements, they could use combines and balers on these newer models. The power shifter rear wheels would allow the WD to move the rear wheels closer to or farther away from the tractor so that they could do different widths of rows without having to move the tractor up off of the ground. The power shifter would work by engaging the spiral rails on the axel and this was a huge hit with all of the farmers of the era. It allowed it to pull three plows with 24 to 30 horsepower. It was over six years in the making but it had plenty of power and was in competition with John Deere. IH was also coming out with more tractor over 40 in horsepower so the competition of the era was stiff. With so much more power, users were now able to back up over implements and hitch them easily when the tongue snapped the groves into place on the hitch. Three point hitches wouldn't catch up to this level for a few more years. With so many improvements it quickly soared to four plow class. It offered a diesel engine that had power steering, never before heard of. From 1953 to 1957 it had made drastic implements and sold over 90,000 WD45s.

Allis Chalmers 616

In 1972, Allis Chalmers also introduced their Model 616. This was their former Simplicity PowerMax. It had orange paint and the hood was a different color. It quickly became the 620 and by 1973 it had 20 horsepower engines. by 1975 it was relabeled to the 720 in order to match the numbering of their now updated small tractors. They appear to be identical except for the fact that the later 720 models had a different upgraded front axle. They would eventually come out with a secondary 616 model with a painted over Simplicity 4216 without any relation or mention of the PowerMax 616.

Allis Chalmers B Hydraulics

By the 1930s, the farming industry was disenchanted with the smaller and cheaper tractors of the era. Tractors on farms had mushroomed from the 246,000 that were available in the 1920s and the 920,000 that were available in the 1930s. This was due to the lower prices on tractors that weren't performing well and it left farmers with a bad opinion of smaller sized tractors. The market was prime for new tractors that worked and was affordable and Allis Chambers took advantage of this well-known fact and did something about it.

By 1937 Allis Chalmers B designed and then marketed their tractors to over 4 million farmers. These farmers were tilling under 100 acres of land. The marketing challenge at this time was for Allis Chalmers to convince the farmers that they needed tractors in lieu of horses to do the job. Allis Chalmer chose a lightweight model that was simple to operate and it worked, farmers began to purchase the tractors for their small farms. These early tractors would cost $495 and weigh in at about 2000 pounds. The price of this tractor included the tires made of rubber and a seat that had a cushion on it. Allis Chalmers focused their sales pitch on telling farmers that it would require far less maintenance than their teams of horses and that it would last longer. Using the governmental research that they had access to as well as their own research data, they began their marketing pitch to smaller farms that would benefit from the more modernized equipment. This offered them a way to effectively market their farm produce and improve production.

Introducing new frame designs, Allis Chalmers was on the market at the right time. Their new designs would offer farmers two advantages. The first was that the farmers could improve their farming and the second was that the angle was reduced meaning that they could see the cultivator when it was being used.

Other innovations that would spur sales on were that a narrower fuel tank offered more support. A thin U-shaped sheet metal piece would hold the gas tank and allow the farmer to see where they were going with the torque tube design.

By 1937 Allis Chalmers had the Waukesha inline engine that was four-cylinders. They used this engine exclusively and produced its own engine with a belt pulley and 1400 rpm.
