Ford Motor Company developed these stationary industrial engines using the standard Ford 8-N tractor engine. They came in various configurations, which included pulleys for flat belt and "V" belt use. They also had direct drives as well as units with a hand clutch. They were used to provide power for air compressors, welders, water pumps, oil well pumps and farm implements. This unit is a model "8NNN" and was mounted on a Dearborn-Wood Brothers combine. Most units did not use a battery and were started with a hand crank. A starter was adapted to this unit for the ease of demonstrating the power unit. A hydraulic brake from a 1997 Saturn automobile was mounted on this engine to demonstrate how the engine performs when a load is applied as it would in its use as a power unit.
