ENGINES OVERVIEW
The Farmall 826 tractor is equipped with either a 5.9L 6-cylinder diesel engine, which offers better fuel efficiency and torque for heavy-duty tasks, or a 4.9L 6-cylinder gasoline engine, providing quicker start-up and lower initial costs. A key advantage of the diesel variant is its durability and longevity under load, making it suitable for extensive farming operations. However, the gasoline engine may be preferred for lighter applications where initial investment and maintenance simplicity are critical.

ENGINE DETAIL 1
The Farmall 826 features a robust International Harvester D-358 diesel engine with a displacement of 5.9L and a high compression ratio of 16:1, providing excellent torque and efficiency for heavy-duty farm operations. Its dual-stage dry air cleaner enhances filtration, ensuring optimal engine performance and longevity. However, the rated RPM of 2400 limits its maximum speed, potentially impacting tasks requiring higher RPMs, so it's best suited for applications with moderate power demands.

ENGINE DETAIL 2
The Farmall 826 is powered by a C-301 gasoline engine with a displacement of 301 cubic inches (4.9L), offering a solid balance between power and efficiency for mid-sized farming operations. Its bore and stroke dimensions (3.8125 x 4.39 inches) indicate good torque characteristics, beneficial for tasks such as plowing and tillage. However, being gasoline-fueled may lead to higher operational costs compared to diesel counterparts, particularly for extensive fieldwork.

TRANSMISSIONS OVERVIEW
The Farmall 826 features a 16-speed two-speed power shift hydrostatic transmission, offering precise control and adaptability in varying terrain conditions. This system enhances operational efficiency by providing seamless shifting without the need for clutching, improving productivity during heavy fieldwork or transport. However, while providing fine gear selection, maintenance of the hydrostatic components can be more complex and costly compared to traditional mechanical transmissions.

FARMALL 826 TIRES
The Farmall 826 features a robust 9.5L-15 Ag front tire setup and an 18.4-34 Ag rear tire configuration, which provide excellent traction and stability, especially in agricultural applications. With this tire combination, the tractor can effectively handle heavy-duty tasks like plowing and tilling, optimizing ground contact. However, the selection of larger rear tires may lead to a higher center of gravity, which can affect maneuverability in tight spaces or uneven terrain.

DIMENSIONS & TIRES
The Farmall 826 tractor features a 105-inch wheelbase, which enhances stability during operation, particularly on uneven terrain. With a weight of 9,860 lbs, it provides sufficient ballast for traction, making it suitable for heavy towing and implements. However, the tire configuration (9.5L-15 front and 18.4-34 rear) may limit maneuverability in tighter spaces, thus making it better suited for larger fields and less confined agricultural tasks.
