ENGINE DETAIL
The International Harvester TD-20 is powered by a robust D-691 diesel engine, offering 134 hp at 1550 RPM with a high compression ratio of 15.06:1, which enhances efficiency and torque at lower RPMs. The substantial displacement of 11.3 liters (691.1 ci) provides significant pulling power for heavy-duty applications, making it ideal for construction or agricultural tasks. However, the gasoline-start mechanism may pose challenges in extreme cold conditions, potentially requiring auxiliary starting aids.

INTERNATIONAL HARVESTER TD-20 TRANSMISSION
The International Harvester TD-20 features a 6-speed gear transmission, allowing for smooth power delivery and flexibility in various operational scenarios. This transmission setup enhances traction control and efficiency, making it suitable for both fieldwork and transport tasks. However, operators must be familiar with gear shifting techniques to maximize performance, particularly in challenging terrain.
MECHANICAL
The International Harvester TD-20 is a crawler tractor featuring contracting band brakes, which enhance its stopping power and control on uneven terrain. Its open operator station provides excellent visibility and operator comfort, but may offer limited protection from environmental elements. Ideal for earthmoving and construction applications, its tracked design ensures superior traction and stability on soft ground, though it may struggle with high-speed transport compared to wheeled tractors.
