ENGINES OVERVIEW
The International Harvester 8-16 tractor features a choice of a 4.1L or 4.6L four-cylinder kerosene engine, providing flexibility in output and efficiency for agricultural tasks. Its ability to run on kerosene allows for cost-effective operations, particularly in farming scenarios where fuel availability and pricing can vary significantly. However, its older design and technology may present challenges regarding parts availability and maintenance compared to more modern tractors, necessitating a knowledgeable operator for optimal performance.

ENGINE DETAIL 1
The International Harvester 8-16 tractor features a robust HC kerosene engine with a 251 ci (4.1 L) displacement, providing efficient fuel utilization for agricultural tasks. Its 4-cylinder, liquid-cooled design with a 4.125x5.00 inches bore/stroke ratio ensures reliable torque delivery at a rated RPM of 1000, suitable for plowing and pulling applications. However, the lower RPM may limit high-speed operations; thus, it excels in applications requiring steady power over prolonged periods.

| Rated RPM | 1000 |
ENGINE DETAIL 2
The International Harvester 8-16 tractor features a 4-cylinder, liquid-cooled engine that efficiently utilizes kerosene, making it suitable for agricultural applications where fuel availability may vary. With a displacement of 283.7 ci (4.6 L) and a bore/stroke ratio of 4.25x5.00 inches, the engine is designed for low-end torque, enhancing plowing and heavy-load capabilities. However, operating at a rated RPM of 1000 may limit its speed, potentially restricting productivity in larger fields compared to higher RPM models.

INTERNATIONAL HARVESTER 8-16 ENGINES
The International Harvester 8-16 tractor features a choice between a 4.1L and a 4.6L four-cylinder kerosene engine, providing versatility in power output. With an 11-gallon primary fuel tank and a 1.5-gallon auxiliary tank, it allows for extended operation, ideal for long fieldwork scenarios; however, it may be limited by its relatively low fuel capacity compared to modern standards. The kerosene fuel type may present challenges in terms of availability and efficiency, but it allows for effective performance in agricultural applications.

TRANSMISSION
The International Harvester 8-16 features an unsynchronized gear transmission with 3 forward gears and 1 reverse, which can present challenges in shifting smoothly under load. This configuration is advantageous for simple operation and durability, making it suitable for farm tasks where precision is less critical. However, the lack of synchronization may lead to increased wear in the gear system and requires skilled operation to prevent grinding during shifts.
| Type | unsynchronized gear |
| Gears | 3 forward and 1 reverse |
MECHANICAL
The International Harvester 8-16 features a 4x2 2WD chassis, which limits traction on uneven terrain but enhances maneuverability on flat surfaces. Its manual steering may require more physical effort, particularly in tight turns, making operator fatigue a potential challenge during prolonged use. The 3-speed unsynchronized transmission offers simplicity and reliability, but slow gear shifting could hinder productivity in rapidly changing field conditions.

INTERNATIONAL HARVESTER 8-16 TIRES
The International Harvester 8-16 features a robust design with 32x4 steel front wheels and 40x10 steel rear wheels, enhancing its durability and weight distribution for agricultural tasks. The larger rear tires improve traction and stability, making it suitable for plowing and heavy tillage on uneven terrain. However, the steel wheels may limit traction on wet ground compared to pneumatic options, potentially affecting maneuverability in adverse conditions.

DIMENSIONS & TIRES
The International Harvester 8-16 tractor features a wheelbase of 85 inches, providing stability during operation; however, its relatively compact size may limit certain stability under heavy loads. Weighing 3660 lbs and equipped with 32x4 front and 40x10 rear tires, it offers decent traction but may face challenges in muddy terrains due to its lighter weight and narrower front tires. Ideal for smaller fields, this tractor is suitable for light to medium agricultural tasks but may struggle on larger, uneven terrains.
