Summary

Describes the technical advances encapsulated in the model '81' tractor released in the early war years. The advances in both metallurgy and engineering occasioned by the war are evident. These tractors were imported from America, and the illustrations and style of the pamphlet suggest it may be American in origin.

The pamphlet presents a great deal of information, including a full listing of the technical specifications. Detailed photographs illustrate the layout of the controls, and the construction of the gear-box and differential.
