The construction of the Steel King is characterized by its substantial mass, weighing 15,870 lbs (7,198 kg). The machine measures 191 inches (485 cm) in length and 95 inches (241 cm) in width. The liquid cooling system is notably large, featuring a coolant capacity of 200 quarts (189.3 liters) to maintain operating temperatures during heavy field loads.
Conclusion
The Hart-Parr Steel King is a representative example of early industrial-era farm machinery. Its heavy construction and high-displacement engine make it suited for steady, high-torque work, serving as a primary power source for early 20th-century agricultural operations.
