ENGINE DETAIL
The Hart-Parr gasoline 2-cylinder liquid-cooled engine, with a displacement of 464.6 ci (7.6L) and a bore/stroke ratio of 6.50x7.00 inches, offers robust torque characteristics, beneficial for heavy-duty applications. Operating at a rated RPM of 750, it is optimized for low-speed, high-torque performance, ideal for plowing and tilling. However, the challenges may include potential vibrations due to its lower RPM coupled with high displacement, requiring effective vibration dampening solutions.

HART-PARR NEW HART-PARR ENGINE
The Hart-Parr New Hart-Parr tractor, powered by a 7.6L 2-cylinder gasoline engine, offers robust performance suitable for medium-duty agricultural tasks. Its simplicity in design can facilitate easier maintenance and lower operational costs, but the 2-cylinder configuration may struggle with higher torque demands during heavy workloads. For optimal use, this tractor excels in lighter applications such as plowing and cultivating, making it ideal for small to mid-sized farms.

TRANSMISSION
The Hart-Parr New Hart-Parr tractor features a simple two-speed forward and one-speed reverse gear configuration, which enhances ease of operation for basic agricultural tasks. This gearbox arrangement can be advantageous for users requiring straightforward control, but may limit its effectiveness in applications demanding variable speed or high torque. Ideal for small to medium-scale farming operations, this straightforward transmission suits tasks such as plowing and planting where lower speeds are generally sufficient.

| Gears | 2 forward and 1 reverse |
MECHANICAL
The Hart-Parr New Hart-Parr tractor features a 4x2 2WD chassis with bull gear final drives, which provide a robust torque transfer but may limit off-road performance. Its manual steering requires more physical effort and may lack the precision of power-assisted systems, while the open operator station offers minimal protection against environmental elements. The 2-speed gear transmission allows for basic speed adjustment, suitable for simple agricultural tasks but may limit operational versatility in diverse applications.

HART-PARR NEW HART-PARR TIRES
The Hart-Parr New Hart-Parr tractor features robust agricultural front tires (28x5) and larger rear tires (52x10), both made of steel, enhancing durability and load-bearing capacity. The larger rear tires provide improved traction and stability in field conditions, making this tractor suitable for heavy-duty operations. However, the steel construction may lead to a harsher ride compared to rubber tires, potentially impacting operator comfort over prolonged usage.
