ENGINE DETAIL
The Hart-Parr Steel King tractor features a robust 2-cylinder kerosene engine with a substantial displacement of 1206.4 ci (19.8L), delivering significant torque for heavy-duty applications. Its bore and stroke of 8.00x12.00 inches (203x305mm) suggest a design focused on low-end power, ideal for pulling loads on challenging terrain at a rated RPM of 400. However, with a coolant capacity of 200 quarts (189.3L), managing temperature could present challenges during extended operations, necessitating efficient cooling systems to prevent overheating.

HART-PARR STEEL KING ENGINE
The Hart-Parr Steel King is equipped with a robust 19.8L two-cylinder kerosene engine, beneficial for delivering high torque at low RPMs, making it suitable for heavy-duty agricultural tasks. However, the substantial fuel tank capacity of 50 gallons (189.3L) implies a trade-off between weight and fuel efficiency, potentially increasing operational costs for smaller farms or projects. This tractor is ideal for large-scale operations where fuel economy is secondary to power and endurance.

TRANSMISSION
The Hart-Parr Steel King tractor features a basic transmission system with two forward and one reverse gear, which provides limited speed versatility and maneuverability. This simplified gearing can be advantageous for straightforward agricultural tasks but may pose challenges in more complex terrain or when greater speed variation is needed. In scenarios requiring frequent direction changes, the reverse gear offers crucial operational flexibility despite the limitations of having only one reverse option.

| Gears | 2 forward and 1 reverse |
MECHANICAL
The Hart-Parr Steel King, with its 4x2 2WD chassis, offers straightforward maneuverability, making it suitable for flat terrain and light-duty agricultural tasks. Its 2-speed transmission provides versatility in speed selection, but may limit performance under heavy loads or challenging conditions compared to modern multi-speed systems. Ideal for collectors and vintage enthusiasts, this tractor represents the evolution of early agricultural machinery but may struggle with traction in muddy or uneven fields.
