Denning farm tractors

Denning was an Iowa based US tractor manufacturer that offered products that were produced in Cedar Rapids. The company was founded in 1989 and offered its machines during the early part of the twentieth century. However, it was forced to cease operations soon, as a result of financial difficulties. 1912 was a significant year in the history of Denning because it sold its patents and fence machinery thereby becoming the Denning Motor Implement Company. Denning disappeared from the list of tractor manufacturers in the year 1918 when it was acquired by the General Ordnance Company. After this, it was renamed as National Tractor. The company operated for just 6 years between 1912 and 1918. During these times, Denning was able to offer only 4 tractor models. This number was much smaller even by the standard of those days and as a result, it hampered Denning’s initial intent of becoming one of the major tractor manufacturers of the country. The tractors offered by Denning had powers ranging between 13 and 33 hp and were thus small machines that could only satisfy the needs and requirements of small clients. Some of the tractor models offered by the company included but were not limited to A & E.
