Allis-Chalmers Rototillers

 Recently I have been compiling my own database from books and online sources. I come across crazy items. We think we know our tractor company well. Then as you dig into its history randomness appears. Today I want to share with you one of those random things I found today reading The Ultimate Guide to Tractors by Jim Glastonbury. Actually two things. First up is the Rotary Tiller, it was Allis-Chalmers first attempt into the tractor business. AC purchased the right to produce it at cost of $10,000 and 6% royalty. Here is a link with a more description. http://www.bungartz.nl/hist-allis-chalmers.html I also stole his photo, so the photo here is same as on the linked website. 

Second AC decided to make a monstrous half track as a tractor. Yeah. We'll give them a pass, it was 1915 no one knew how tractors were supposed to look like. So here are two photos I found on internet of the 1915 half-tracks.

Farmall A

 

I have many fond memories of raking hay with this tractor along with doing other things with it around the farm. One thing I can tell you, is that it is a gutsy little tractor. It is a very distinctive tractor because of it's offset engine. And in all it is a very beautiful tractor, I mean it is a Farmall-it's got that pretty red paint.

The Farmall A was built between 1939-1947. This is one of those instantly recognizable tractors for it's offset engine. The design of the A was to allow a full unobstructed view of cultivating right in front of you. With the engine, frame, and drive train off to the left side of the tractor and the seat and steering on the right side right above and behind the cultivator. This allowed the "cultivision".
There were two other variants of the tractor the AV and the AI. The AV was a high crop version of the A, the V standing for vegetable. The AI was an industrial version of the A, the I standing for Inudstrial. It also had no PTO and had a stronger rear end.

The A had an IH  1.9L 4 cylinder gasoline or kerosine (distillate) engine. The transmission was 4 forward and 1 reverse. It ran on a 6 volt system. It was claimed to be a 13-16 HP 1 plow tractor, however the Nebraska test revealed it to be a 16-18. The belt pulley allowed a 8.5 x 6 belt to run at 1156 RPM. The A had a standard set of 4-15  4ply front tires and 8-24 4ply rear tires.

From 1939-1945 it was advertised under the McCormick-Deering Farmall banner, in 1946 it was changed to McCormick Farmall banner. It was built in both the Chicago and Lousville factories, with Louisville only making it in 1947. The engine was a updated version of the F-14's 113ci engine. The distilate engines were only in 1939 and the later years were only the more powerful gasoline engines. The tractor also had a attatchment for a pneumatic lift called a "lift-all" system it was powered by the exhaust of the tractor. It was made to compete with the Allis-Chalmers B which was released in 1937 as a pilot run and 1938 in full production. International Harvester seeing the success of the B saw the need to compete in the small tractor market. Improving on the concept IH offset the engine, increased the transmission gears from three to four, and increased the horsepower Not to be outdone Allis put a bigger engine in the B, Farmall responded with the Super A in 1947. Options for the A were electric start, Pneumatic "Lift-All", and adjustable front axle. Tires could also be swapped for 5-15 front; 9-24, 10-24, 11-24 rear; and 4-30, 5-30 duals for the rear.

Allis-Chalmers WD-45

 Allis Chalmers WD-45

For many people this tractor is Good Ol' Allis. Many people believe that this tractor is the most important tractor made by Allis. The WD-45 started it's life in 1953 as an update from the WD which in turn was an update from the WC. Because of this the style and overall dimensions of the machines are similar, however underneath the hood it is more powerful. It had the "Power Crater" 4x4-1/2"  bore and stroke. When A-C acquired Buda it placed the 6BD-230 diesel engine as an option for diesel. This would make the WD-45 the first Allis with a diesel engine. It was advertised as a 33-39 HP tractor but after the Nebraska tests it was rated at 38-44 HP. In 1954 they offered the WD-45 with the "Snap-Coupler" power lift system. The first Allis-Chalmers with power steering when it was added in 1956. Another item that made this a great tractor was its hand clutch in addition to its foot clutch, which would give it a semi-live power. At the time when it was marketed it was the most powerful tractor of its size for sale. Some variants were wide front, narrow front, cane special, and adjustable axle. The last WD-45  was made in 1957 after a production run of 90,382. In 1956 a gas engine wide front WD-45 cost an average of $2380. 

People who own a WD-45 are also forever cursed with always referring to WD-40 lubricant as WD-45.

Meaning of Numbers (xx-xx)

 Ever heard of a Hart-Parr 12-24? Ever wondered what the 12 and 24 stood for?

The origin of this type of tractor naming goes back to the early years of tractors. It stood for the HP rating of the tractor. In this case 12 would stand for horsepower (HP) at the draw bar (pulling power) and 24 stood for the HP at the belt (production power).

So why is there two different numbers?

Well it had to do with the early tractor's capacity to do work. The configuration of early tractors were to either pull something heavy as in a plow. Or it would be stationary to power, to say, a thrasher. Rarely would the two be used in a single job. So knowing how much the tractor could produce in each perspective job was crucial.

If you only know one number, don't worry, because as a general rule the belt usually could produce twice the amount of power as the draw bar.

This period of tractor naming lasted from about the time tractors became popular and well into the 1920's.

Don't be fooled though. Some manufacturers falsified their tractors capabilities to increase their sales. This was actually a common practice used by corrupt tractor manufacturers and would not be done away with until the Nebraska Tests set a standard for tractor capabilities.

Farmall SuperMTA

 FARMALL SUPER M-TA

The Super M-TA was made only in 1954. 26,924 tractors of this type had been manufactured by IH.

Serial Numbers of this tractor are located just in front of the starter. Numbers start at SM-TA60001 to SM-TA83523.

Horsepower for this machine is 44.23 at the drawbar and 47.07 at the belt.

The Super M-TA (SMTA) was the first Farmall tractor that had live power. This was in the form of Independent PTO.

The TA on the Super M allowed the tractor to quickly downshift in the field. This gave the farmer the advantage in twice the gear selection and the ability to shift on-the-go. The gear ratio of the TA was 2.63:1.

The Torque Amplifier (TA) is just what it sounds like. It gives more torque to the tractor. In basic it reduces speed and transfers that energy over to pulling power. Or it could transfer pulling power into speed.

The SMTA would be in the beginning of the quest for more power for IH in the tractor race that sought for more power and higher gear ratios.

The M is the grandmother tractor of the SMTA. The M led to the development of the Super M. The Super M was the first tractor to mount the TA on and the SMTA was born.

The SMTA like the M was a very versatile tractor, it was produced in many different variations. It had three different front end options available a single tricycle - most commonly used for rice; a dual tricycle - normal front end; and the wide front - another option for farmers. The tractor also had different fuel options it had: gas, diesel, distillate, and LPG. Other variants of the SM-TA are the SMD-TA, SMV-TA, and the SMDV-TA.

The average cost a Super M-TA sold for in 1954 was around $2500. Today (2014) they sell for around $5500-$6000.

So what is rarer than a Super M-TA? A SMTA  TA delete. Yes there are those out there. The evidence is in the size of the tractor. The SM-TA is inches longer than the Super M. A simple way to tell the difference between a true TA and TA delete is the SMTA had wings on its emblem. The SMTA  TA delete had the wings removed.

Why was the SM-TA made only one year? Because International Harvester in 1955 came out with its number series and the SMTA became the 400. There is very little difference between the SMTA and the 400, most of it is just restyling of the decals and different tin work.

The Super M-TA is my favorite tractor. I love to start her up and here her 4 cylinders purrrrrr. Love to sit atop the beast and do hay with it. Better yet take her to shows and catch the envious glances in the crowd.

Minneapolis-Moline Thresher Flyer (collection)

This is one of the first things that I bought off of Aumann Auctions. This is a mailer that would be sent out to advertise Minneapolis Moline's thresher. The two threshers advertised are the 28x46 and the 32x54 - brilliant naming. What I find the most interesting is how the thrashing operation is set up. Threshing is so far removed from most of us that seeing where people would likely be stationed is informative. The cutaway is cool as it gives an insight to how the machine does its job.
