INTERNATIONAL HARVESTER 4186 ENGINE
The International Harvester 4186 is powered by a robust 7.1L 6-cylinder diesel engine, offering high torque output ideal for heavy-duty agricultural tasks. With a substantial 100-gallon fuel tank, it provides extended operational time, minimizing refueling intervals during long workdays. However, the tractor's weight and size might limit maneuverability in tighter spaces, making it better suited for larger fields and more open terrains.

TRANSMISSION
The International Harvester 4186 features an 8-speed forward and 4-speed reverse transmission, allowing for versatile operation in varying field conditions. The inclusion of a 355.6mm dry disc clutch enhances durability but may require more frequent maintenance than hydraulic alternatives. Operators may benefit from using lower gears for heavy-duty tasks, while the higher gears facilitate faster transport between sites, balancing power and speed effectively in agricultural applications.

MECHANICAL
The International Harvester 4186 tractor features a robust 4x4 drivetrain, providing enhanced traction on varied terrain, making it ideal for fieldwork in challenging conditions. Its hydraulic power steering improves maneuverability, while the hydraulic expanding shoe brakes ensure effective stopping power, especially when hauling heavy loads. With an 8-speed transmission, operators can efficiently manage different operational speeds, though the complexity of the gearbox may require more maintenance compared to simpler transmission systems.

INTERNATIONAL HARVESTER 4186 TIRES
The International Harvester 4186 tractor is equipped with 23.1-26 tires both on the front and rear, providing excellent ground traction and stability, especially in agricultural applications. This tire size enhances flotation over soft soils, but may limit maneuverability in tighter spaces due to the broader footprint. Ideal for large-scale operations, the 4186 can efficiently handle heavy implements, although operators should be aware of potential soil compaction with prolonged use on sensitive terrains.

DIMENSIONS & TIRES
The International Harvester 4186 tractor features a 102-inch wheelbase, which enhances stability and maneuverability, particularly in tight field operations. Weighing 15,900 lbs provides substantial traction, making it suitable for heavy-duty applications such as plowing and tilling; however, its weight may pose challenges in less stable soil conditions. The uniform tire size of 23.1-26 on both front and rear improves balanced weight distribution but may limit versatility across varying terrains compared to tractors with adjustable tire options.
