Holt 75 Artillery Tractor.

The Holt 75 was a heavy artillery tractor produced in the early 20th Century by inventor Benjamin Holt in the United States. At first it was used exclusively for agricultural needs, but with the outbreak of the First World War it was brought into military service as a mover of heavy artillery pieces that could not be hauled by the physically limited horse-drawn harness. In addition to Great Britain, these machines were also used by France and the United States. A total of 2,000 tractors of this type took part in the First World War. They became the forerunner of a major new element in the mechanized army - the artillery tractor, since used with great success to the present day.
