Four Drive Tractor Models & Specifications
|
The Fitch Four Drive tractors proved to be extremley effective in the rice fields of California, Texas and Arizona. Even though rice is grown and harvested under water, the Fitch tractors easily handled the binders and other rice working machinery under these difficult conditions. The same results were obtained in the cotton fields in the Southwest United States. The tractors seemed to perform the best in conditions where the traction was the least, either on sand, gumbo (a fine silty soil that forms an unusually sticky mud when wet), muck or other wet and soggy ground. One of these places where they were extensively used was the Tulare Lake bottom, a sunken lake south of Fresno, CA. The first Four Drive Tractor was produced in 1916 and was known as "The Fitch". "The Fitch" was powered by a 4-cylinder Waukesha engine, had a wheelbase of 72 inches and an extreme width of 68 inches. The tractor had a turning radius of 8 feet, weighed 3,000 pounds with the tanks filled and sold for $1,000. This was the model that was featured in the March 16, 1916 edition of "Motor Age" magazine.
In July 1918, a Fitch Four Drive 20-35 model undertook a 100-acre non-stop demonstration test starting the day prior to the National Tractor Demonstration at Tyler Field in Wichita, Kansas. It was the only tractor at the site conducting a demonstration, so hundreds of visitors were on hand watching the feat. The tractor pulled four fourteen-inch plows to a depth of seven inches deep in a gumbo with approximately sixteen inches of wild flax on the ground and five old straw stacks to turn under. Fuel was poured into the tank and engine and transmission oils were added while not stopping the engine. The grease was not be changed until after the test was complete. During the first night, rain poured down from about eleven o'clock until after daylight. The tractor continued without intermission through the rain completing 15 of the 100 acres in 12 hours and then ran for about 60 more hours thereafter until the job was done. The whole 100 acres was plowed in 88 hours - an incredible feat for that time. The Fitch showed that drive on all four wheels would do the unbelievable. In addition to the show on the field, a display tent was setup with C.A. Watson, who was in charge of the Fitch activities, pointing out the details of a second Fitch Tractor's fine construction. In 1919, the company changed the design of the tractor so that it was heavier and had a more efficient kerosene burning motor. The 20-35 and the 16-26 models allowed the company to secure a solid footing and lead to the firm selling its entire 1920 output before the year started with extensive advertizing in 1919 and 1920. Around 1920, a 20-35 model Fitch Four Drive - with a weight of 5,100 pounds - pulled 7 trailers loaded with hay and oats having a gross weight of 49,000 pounds at a US Government Tractor Test at Marfa, Texas. In 1928, the company introduced a modified four drive tractor for heavy utility work. Known as "The Cat" Model E 15-30, it featured a Waukesha 4-cylinder engine vice the Climax 4-cylinder that powered the standard Model D 20-35 "Fitch" Four Drive. "The Cat" was shorter, wider and stockier than the Model D and can be identified by the existence of rear wheel covers and that all four wheels are the same size. The word "Cat" was discontinued in September 1929.
The booklet featured photos of tractors conducting work in the United States (Georgia, Michigan, Missouri, Kansas, Iowa and the Pacific Coast) and from Portuguese East Africa (now Mozambique) and New Zealand and a testimonial from the country of Montevideo. From July 1 to 17, 1929, a Four Drive Model E "The Cat" 15-25 (serial #3017 weighing 6,500 pounds with 4" spade lugs) was subjected to a standardized test conducted by the University of Nebraska Agricultural Engineering Department at Lincoln, Nebraska. The engineers in charge of the test concluded that the advertising literature submitted with the application for the test contained no claims or statements that were unreasonable or excessive. The actual rating code on the tractor tested was a beter than advertized rating of 18-28. |

Tractor models of that time were designated by a two number rating code. The first was the draw bar rating - the amount of horsepower while in intermediate speed when a load was attached at the draw bar. The second was the horsepower when a load was run off of the belt pulley. So a 20-35 model tractor had 20 horsepower from the draw bar and 35 from the belt. [return] |
