The 40-80 Avery was built from 1913 to about 1924 according to Clifford Caron, Fairbault, Minnesota in his article in the July-August 1968 G.E.M. R.B. Gray in his Development of the 0Agriculture Tractor in the United States gives the following specifications for the 1913, 40-8-- Avery 500 r.p.m., 4 cylinder horizontal double-opposed engine 7-3/4' bore with 8' stroke, thermosyphon cooling system with induced draft in cooling tower; double carburetor for gasoline and kerosene fuel; high-tension ignition, pump and splash oiling; friction clutch in belt pulley; final drive, bull gear and pinion; two forward speeds, 1-3/4 and 2-2/3 m.p.h. effected by sliding frame. For a couple of years each tractor was provided with 3 separate pinions to slip on end of crankshaft to alter road speeds, by use of the sliding frame. Later models had two speeds incorporated in the transmission. In 1914 the price from the Avery catalogue for the 40-80 was $2,650 F.O.B. Peoria. This is shown in the February 1962 E.&E. from Avery catalogue 1914 sent in by Ted Worrall, Loma, Montana. The tractor is called a 'Light-weight' gas and oil tractor. The weight is listed as 20,000 pounds. The Avery trademark was 'The Bull Dog Line.' Other models shown in this 1914 catalogue are the 20-35 8-16, 25-50, and 12-25.

In an article in the August 1962 E. & E. by Marcus Leonard describing the Hutchinson Fair and their tractor tests, he says the plowing field in 1915 was a 'frog pond' and the five Avery tractors were equipped with extension rims.

T.F. Kruger in his Observation in the March-April 1969 G.E.M. says the Avery Company started enclosing the governors on their tractors the later part of 1918. If only more people with the experience, background and first hand knowledge that Mr. Kruger has would contribute articles, the rest of us would gain a great deal of information.

The Nebraska test for the 40-80 Avery with engine ZB 1073 Chassis 25259 was test #44 in 1920. The test weight was listed as 22,000 pounds. The rated load belt horsepower was 65.73 while the rated load horsepower on the drawbar was 46.93. The maximum pounds pull was 8,475 pounds. Amos B. Stauffer, Ephrata, Pa. in an article on the Happy Farmer tractor in the September-October 1968 G.E.M. says the Avery men were delusioned because their prony brake was out of adjustment. After 1920 the tractor was rated 45-65 by the company.

B.B. Gray in part II of his book stated the production of the 46-65 horsepower model powered with a 4-cylinder so called 'Draft Horse' engine began in 1926. But I think this paragraph must have gotten in the wrong year in his book. It looks to me as though this should be in 1921 or 1922. Also the Avery company changed to the core type radiator with pump and fan about this time and from a sliding frame to a sliding gear transmission.

An advertisement in the December 1919 Tractor and Gas Engine Review lists sizes of Avery tractors as: 8-16, 12-25, 14-28, 25-50, and 40-80; all built alike with the same standardized design, including the famous 'Draft Horse' motor and 'Direct Drive' transmission. In the June 1920 Tractor and Gas Engine Review the Avery advertisement mentions the 20-35 hp as being the firstAvery tractor built. The May 1920 issue of the same magazine gives the story of the ignition on the first Avery in a K.W. magneto advertisement. This tractor was bought by Frank Gerry, St. Charles, Minnesota in 1911.

The 40-80 Avery #5301 here at Makoti was unloaded in Plaza, North Dakota in 1916. Mr. John Scholtz of Parshall helped unload this one and one other from the railroad car. One was bought by Bob Rasmussen of Raub. This one John Scholz drove, breaking and seeding flax with eight bottom plow packer and drill. He said sometimes the rounds were four miles long. They had a large enough crew so the tractor could be run day and night beginning in the spring as soon as the frost came out of the ground and working into the early summer until the people thought it was too late for a flax crop to mature in the season. One crew worked a twelve hour shift so the crews changed off.

The other one was bought by Jessie Schaffer, Roseglen, North Dakota. This is the one Clarence Schenfisch bought and restored for the Makoti Golden Anniversary in 1961. He had to replace about 60 of the copper tubes in the radiator, along with other restoration work. In the 1969 show the tractor was driven by Jessie's son, Herb Schaffer, with help from Don Nelson, Makoti.

Some other Avery tractors of this size in the area are as follows; engine ZB723 chassis 17968 owned by John Sandstrom, Lonetree. Roy Peterson, Ryder, has a 45-65 model. Clifford Ruff, Edgley, is restoring a 40-80. Then at a recent auction sale one was sold and it will be restored and will appear at New Rockford. This is a 40-80 chassis 1067, about a 1913 model. George Hedtke is from Davis Junction, Illinois. There is also one pictured at Grand Island, Nebraska. This is in the September 1964 E. & E., a later model Avery 45-65 which is now in the Stuhr Museum. This tractor was purchased for the late John Thieszen, Henderson, Nebraska. This tractor was bought from South Dakota and John restored it. The one on the cover of the January-February 1971 G.E.M. is also pictured in the February 1963 E.E. showing the tractor in use in 1914. This one is owned by Wm. Morganfield, Winner, South Dakota. The cover picture for the 1971 G.E.M. is with the negative wrong side up. The Avery has the belt pulley on the right side not the left.

Does anyone know the history of the Avery Company? When and how did the Avery Company begin? Where did the name Avery come from? What became of the Avery Company?

Does anyone know what happened to the Avery Company production tractor records? How did the Avery Company number their tractors? Did all models use the same series of numbers for a given year or did each model have its own number system? Does anyone have any parts books with Avery serial numbers for the tractors?
