First Generation Tractors

1911 International Mogul Model C
Year: 1911
Manufacturer: International Harvester
Model: Mogul Model C
Serial Number: TP244
Horsepower: 25 HP @ 240 RPM
Gears: 1 Forward, 1 Reverse
Fuel: Gasoline, Kerosene/Water
Cooling: External Evaporative Pumped Water

Description: The Model C uses a 25 HP single-cylinder hit-and-miss International Famous engine. Essentially, the Mogul is a stationary engine mounted on a frame with wheels and a drive train. The "Famous" engine is actually International's brand name - not a reference to the fact that the engine was well-known.

The unique evaporative cooling system works by pumping warm water from the engine over the top of external wire screens. As the water cascades down the screen, some of it evaporates and cools. It then collects in the holding tank to be picked up by the pump and recirculated through the engine.

862 of these 25 HP Model C tractors were produced between 1911 and 1914. All were built at International's Milwaukee Works. The serial number of 244 suggests this tractor was built around autumn of 1911. Now over 100 years old, this tractor is one of the oldest in the Pioneer Acres collection.

Aultman & Taylor 30-60
Year: circa 1918
Manufacturer: Aultman & Taylor
Model: 30-60
The Aultman & Taylor Machinery Company is worthy of note for many reasons, but in particular because it evolved from a continuous series of business endeavors by Cornelius Aultman and Henry Taylor starting around the time of the civil war in the United States. The site of production was Mansfield Ohio, where it stayed until the demise of the company in 1923. This is a very long lifespan for any company, and was in no small part due to the high quality of workmanship and design that went into their products. So it was that in 1910, when the first Aultman-Taylor 30-60 internal combustion powered tractor came into being, it was soon one of the leading contenders in dominating the farm and industrial mobile power markets. The period from around 1907 to the early 1930’s is unique in history for the simple reason that the emerging oil industry was able to produce kerosene in quantities and at a price that made it an attractive fuel for the first generation of petroleum powered traction engines. Hence, the 30-60 was designed to burn kerosene. The tractor was literally built around an engine patent that had become available during this time that was also offered by the Aultman & Taylor Machinery Company as a stationary power source. The 30-60 frame was unique in the industry, being formed from a ‘locomotive truss’ design that was very strong while being comparatively light. The 30-60 was the largest of a series of models that included a 22-45 and a 15-30. It incorporated a state-of-the-art cooling systems and featured huge 90-inch drive wheels. One interesting feature was the patented single speed transmission control that was implemented on a single lever. An adjustable water injection system was supplied to prevent pre-ignition of the kerosene under conditions of heavy load.

1918 GMC Samson Sieve Grip
Year: 1918
Make: GMC
Model: Samson
Engine: Inline 4 Cylinder
Wheels: Cast Iron
Weight: 5,800 pounds

GMC saw that Ford was making inroads with its Fordson line of tractors in the early 1900's and in an effort to quickly gain some of that market, it purchased the Samson Tractor Company in 1918. Unfortunately, even though the Sieve Grip was a decent tractor, it didn't sell well and was finally discontinued in 1923.

This tractor has an inline 4 cylinder motor that has its speed regulated by a very advanced (for its time) and innovative electric governor that also acts as a generator to recharge the battery. It even has an electric headlight so the tractor could be used at night.

The cast iron wheels are the most visually distinctive feature and are the reason that the tractor is called the Sieve Grip. The clutch is hand operated and tends to grab suddenly so the tractor is either moving or it's not - there isn't much in between.
