The Oliver 70 was built in 1946 (this model was built between 1937 and 1948). It has been modified to add a second smoke stack. It has a six-cylinder gasoline engine, six-speed transmission, electric lights and starter. Two Oliver tractors were used on the east end of the island. The Gherini family brought the first Oliver tractor to the island in 1954. A second Oliver tractor came to the island in the 1960s. The Oliver was a versatile piece of equipment. It has a fly wheel that was used to run well pumps in times of emergency when engines (usually the reliable Briggs and Stratton) broke down. A large belt was attached to the fly wheel of the Oliver and the fly wheel of the pump.
