Series 3E1-3E51, 1933 only.

The DIESEL SEVENTY used the diesel engine from the DIESEL SIXTY FIVE in a new large chassis and was produced only briefly in 1933.

Unlike many tractors of the period, the DIESEL SEVENTY was made in just one version with a 78 inch gauge.

It is roumoured that only two DIESEL SEVENTY tractors left the factory, the others being fitted with D11000 engines and sold as DIESEL SEVENTY FIVE tractors

The Diesel SEVENTY is extremely rare and very few are known to have survived. The example below was found in Hawaii.
