Electric Tractors (Sep, 1936)
The key to a good electric tractor is to sup-supply the current.
THE Soviet Union increasingly widens the application of electric power to agriculture. The large network of electric power stations has made it possible to use electricity in running tractors, and other agricultural machines.
The photo shows an electric caterpillar tractor. Above the tractor cabin is mounted a drum for the cable that sup-supplies the current.
