  • Turn Tractor
    The Square Turn Tractor, built in Norfork, Nebraska, from 1916 to 1919 carried a three-plow gang under the tractor frame. The engine developed 18 HP on the drawbar and 35 HP on the belt.
  • Four-Wheel Farm Tractor
    A Four-Wheel Farm Tractor: The Leonard Tractor Company of Gary, Indiana, produced this tractor in 1917. The 4-cylinder 'Buda' motor developed 30 horsepower on the belt and was designed to pull three plow bottoms. It underwent field trials in Michigan and Canada. This odd machine featured two transmissions: one below the frame and the other above the frame.
  • Three wheel tractor
    A Three Wheel Tractor: The Gray tractor was built in Minneapolis in 1915. Drive wheel is a large drum five feet in diameter. 20-35 HP. Waukesha 4-cylinder motor. Weight, 8,000 pounds. Price, $2,150 (which translates to roughly $43,500 in today's money).
  • Gray Tractor
    The Gray tractor with umbrella.
  • Unorthodox tractor
    Strait's Tractor: This unorthodox tractor was built by the Killen-Strait Manufacturing Company of Appleton, Wisconsin in 1914. It weighed 11,000 pounds and developed 50 HP on the belt. It was priced at $2,250 (which would be about $45,600 today).
  • 'Happy Farmer' Tractor
    1918 oddball: 6-12 HP motor mounted on a simple chassis: La Crosse "Happy Farmer" Tractor, La Crosse, Wisconsin.
  • Four Wheel Drive Tractor
    A Four Wheel Drive Tractor: 1918, The Heer Engine Company, Portsmouth, Ohio.
  • Tom Thumb Tractor
    An oddball tractor: Tom Thumb Tractor Co. of Minneapolis built the oddball Tom Thumb Tractor in 1915. It was powered by a Waukesha motor which developed 12-20 HP. It was equipped with a Bennett carburetor, a Dixie ignition system, Splitdorf spark plugs and Perfex radiator. Its impractical construction led to its early failure.
  • Three Wheel Tractor
    A Three Wheel Tractor: This Simplex tractor was built by the Simplex Tractor Company located at 1615 Central Avenue in Minneapolis. The first Simplex tractor was built in 1913. One large drive wheel in the rear. 15-30 horsepower. 4 cylinder motor.
  • Boring Tractor
    The Boring Tractor was manufactured by the Boring Tractor Corporation of Rockford, Illinois.
  • K-T tractor
    A Three-Wheel Tractor in 1916: The Kinkead Tractor Company manufactured the K-T tractor in Minneapolis, Minnesota. 12-20 HP, one big drive wheel. Dr. Charles H. Mayo of Rochester, Minnesota, purchased one of these tractors.
  • Bull Tractor
    A Three Wheel Tractor: 1914. The Bull Tractor, manufactured by Bull Tractor Company of Minneapolis, Minnesota, sold for $395 (which translates to about $8,000 today). One drive wheel in the furrow; one land idle wheel; one steering wheel in front.
  • 4 cylinder Waukesha motor
    A Two Wheel Tractor: The Line Drive Tractor, Milwaukee, Wisconsin, 1916. 15-25 HP, a 4 cylinder Waukesha motor. Speed 1 to 4.25 miles per hour.
  • Two Wheel Tractor
    A Two Wheel Tractor: 1917. The John Noble Tractor was manufactured by the John Noble Company in Kansas City, Missouri. 30 HP motor, weight 3,000 pounds. Speed, 2.5 mph; chain drive.
  • 60 horsepower four cylinder motor
    The Nevada Auto Plow manufactured in Nevada, Iowa, featured a 60 HP four cylinder motor to handle a gang of three plow bottoms. A limited number of these tractors were on the market in 1918.
  • Line-Drive Tractor

Tractor design was an issue facing manufacturers from 1900 to 1920 when approximately 500 companies built tractors for use in American agriculture. This tractor boom resulted in much trial and error because factory engineers lacked experience in producing tractors for general farming. As a result, they built machines of great diversity ranging from the sensible to bizarre mechanical monstrosities.

At the time no one seemed to know how many wheels should support a tractor, therefore they appeared mounted on two wheels, three wheels, four wheels or caterpillar tracks. This occurred in spite of the fact that farm steam engines had been manufactured for almost a century.

In addition, opinions on how the power from the motor should be carried to the ground varied. Some tractors came out with only one drive wheel. At a tractor demonstration held at Fremont, Nebraska, in August of 1916, fourteen different companies supplied tractors with only one drive wheel. The other 36 companies at this event mounted motors on two drive wheels, four drive wheels or on moveable tracks. Many employed the tricycle principle with one steering wheel in front and the drive wheels in the rear, or the reverse featuring the steering wheel in the rear and the drive wheels out in front.

One of the most radical designs made use of a big drum to replace the conventional drive wheels. The Gray tractor built in Minneapolis was driven by a drum five feet in diameter and five feet wide.



Some engineers thought farmers wanted to drive their tractors like a team of horses with the power out ahead of the operator. The Line-Drive Tractor, built in Milwaukee, Wisconsin, was actually driven with a pair of lines, or reins. The motor mounted on two drive wheels did the pulling with the driver seated on a farm implement which trailed behind. The Moline Universal Tractor, manufactured by the Moline Plow Company of Moline, Illinois, in 1915, eliminated the reins but extended the steering wheel on a long shaft which permitted the farmer to sit on a plow and drive the tractor in front of him.

Another innovation placed the plows under the tractor so the operator could look down to see the plow at work, rather than twist his neck to observe the plow being trailed behind. The Square Turn Tractor Company of Norfolk, Nebraska, carried a gang of three plows beneath the tractor frame.
