ENGINE DETAIL
The International Harvester 10-20 is a durable, kerosene-fueled tractor featuring a robust 2-cylinder, liquid-cooled engine with a significant displacement of 530.9 ci (8.7 L), which delivers noteworthy torque for heavy-duty applications. Its bore and stroke of 6.50 x 8.00 inches (165 x 203 mm) indicate a long-stroke design that favors low-end power, making it suitable for plowing and tilling in challenging terrains. However, the rated RPM of 575 may limit its top-end speed, highlighting the need for careful gear selection to optimize performance based on load and field conditions.

INTERNATIONAL HARVESTER 10-20 ENGINE
The International Harvester 10-20 tractor is powered by an 8.7L two-cylinder kerosene engine, offering efficient fuel combustion and lower operational costs compared to gasoline engines. Its robust design supports a versatile range of agricultural operations, but the reliance on kerosene may pose challenges in fuel availability and handling compared to more common fuels. This tractor is ideal for vintage farming applications or restoration projects, appreciated for its durability and historical significance.

TRANSMISSION
The International Harvester 10-20 tractor features a simple gear transmission system with 2 forward gears and 1 reverse gear, which limits its speed variability but enhances durability and reliability for basic agricultural tasks. This basic configuration is advantageous for straightforward operations such as plowing and harrowing, where consistent torque is more critical than high-speed performance. However, the limited gears may challenge operators seeking versatility in varied terrains and conditions, as the capability to adjust speed and power delivery is restricted.

| Gears | 2 forward and 1 reverse |
MECHANICAL
The International Harvester 10-20, with its 4x2 2WD chassis and manual steering, is designed for straightforward operation in agricultural settings. The open operator station provides good visibility but lacks weather protection, making it ideal for use in temperate conditions. With a 2-speed transmission, it offers moderate versatility for various tasks, though its limited speed options may challenge its efficiency for larger operations requiring faster transport capabilities.

INTERNATIONAL HARVESTER 10-20 TIRES
The International Harvester 10-20 features 36x6 steel front and 54x10 steel rear wheels, providing robust stability and excellent traction for agricultural tasks. The larger rear wheels enhance power transmission and reduce soil compaction, making it ideal for heavy-duty plowing or tilling. A potential challenge may be the tractor's weight distribution, which could affect maneuverability in tight spaces on uneven terrain.
