ENGINES OVERVIEW

The International Harvester 826 features a robust 5.9L 6-cylinder diesel engine, providing high torque output ideal for heavy-duty applications, while the alternative 4.9L 6-cylinder gasoline engine offers a higher RPM for lighter tasks, serving diverse operational needs. Key advantages of the diesel variant include improved fuel efficiency and durability under load, although challenges may arise from higher initial costs and maintenance for the diesel system. Scenario-wise, the diesel engine excels in tillage and plowing, whereas the gasoline version may be more suitable for lighter farming tasks or small-scale operations.

ENGINE DETAIL 1

The International Harvester 826 features a robust D-358 diesel engine with a significant displacement of 5.9L, offering high torque at lower RPMs, ideal for heavy-duty farming applications. Its dual-stage dry air cleaner enhances engine longevity by improving air filtration, but the higher compression ratio of 16:1 may lead to increased noise and vibrations during operation. This model operates optimally around 2400 RPM, making it suitable for both fieldwork and transport scenarios, though operators should monitor starter battery health to ensure reliable performance.

ENGINE DETAIL 2

The International Harvester 826 features a robust C-301 gasoline engine with a displacement of 301 cubic inches (4.9L), providing substantial power for various agricultural tasks. Its 3.8125x4.39-inch bore and stroke configuration suggest a strong torque output, advantageous for heavy-duty applications such as plowing and tilling. However, owners should be mindful of fuel efficiency and maintenance considerations with a gasoline engine compared to diesel alternatives, especially in large-scale farming scenarios.

INTERNATIONAL HARVESTER 826 ENGINES

The International Harvester 826 tractor features a robust 5.9L 6-cylinder diesel engine, providing superior torque and fuel efficiency for heavy-duty agricultural tasks. The option of a 4.9L 6-cylinder gasoline engine offers versatility, though may sacrifice some power compared to its diesel counterpart. With a substantial 37-gallon fuel tank, operators can run longer without refueling, enhancing productivity in large fields; however, weight distribution and fuel management must be carefully considered for optimal performance.

Type	two-speed power shift
Gears	16 forward and 8 reverse

TRANSMISSION 2

The International Harvester 826 features a hydrostatic transmission, providing infinite forward and reverse speeds for smooth operation and enhanced maneuverability, particularly in tight spaces. This system allows for precise control of speed and direction without the need for clutching, ideal for tasks requiring finesse like mowing or planting. However, hydrostatic systems can lead to increased wear under heavy loads and may require more maintenance than traditional gear systems.

Gears	infinite forward and reverse

MECHANICAL

The International Harvester 826 tractor features a versatile 4x2 configuration with optional 4x4 MFWD, providing adaptability for various terrain conditions. Its power steering ensures ease of maneuverability, while the hydraulic dry disc brakes offer reliable stopping power, crucial for safety and control in demanding operations. The 16-speed transmission with two-speed power shift allows for efficient speed management, making it suitable for both fieldwork and transport scenarios, although the open operator station may lack weather protection in harsh environments.
