ENGINE DETAIL
The International Harvester Hydro 85 features a robust 4-cylinder diesel engine with a 4.0L displacement, providing a gross power output of 80hp at a rated speed of 2300 RPM, and an impressive torque of 194 lb-ft at 1600 RPM, which is advantageous for heavy-duty applications like plowing and hauling. The indirect fuel injection system enhances fuel atomization, contributing to efficient combustion and lower emissions, but may be more susceptible to injector fouling compared to direct systems. With an electric starter operating at 12 volts, the Hydro 85 offers reliable ignition, making it suitable for various operational scenarios while requiring routine maintenance to ensure optimal performance.

INTERNATIONAL HARVESTER HYDRO 85 ENGINE
The International Harvester Hydro 85 features a robust 4.0L 4-cylinder diesel engine, providing strong torque and fuel efficiency, ideal for medium-duty agricultural tasks. Its 29.6-gallon fuel tank ensures extended operational time, reducing the frequency of refueling during long workdays. However, potential challenges include the weight distribution considering the size of the tank and the engine's performance in high-demand conditions.

TRANSMISSION
The International Harvester Hydro 85 features a hydrostatic transmission, allowing for infinite speed control in both forward and reverse, enhancing maneuverability and ease of operation. This system eliminates the need for gear shifting, which can reduce operator fatigue during prolonged use, especially in varied terrain or for tasks requiring precise speed adjustments. However, the hydrostatic system may be less fuel-efficient under heavy loads compared to traditional gear transmissions, necessitating careful management of throttle usage to maintain optimal performance.

| Gears | infinite forward and reverse |
MECHANICAL
The International Harvester Hydro 85 features a hydrostatic transmission, providing smoother power delivery and ease of operation, particularly beneficial for tasks requiring frequent speed adjustments. The tractor's available 4WD (MFWD) enhances traction in varied terrain, while the hydraulic wet disc brakes provide reliable stopping power, essential for safety during heavy-duty applications. However, the limited 4x2 option may affect performance in challenging conditions, making the 4WD model preferable for rigorous farming tasks.

INTERNATIONAL HARVESTER HYDRO 85 TIRES
The International Harvester Hydro 85 features a Hydrostatic transmission, providing seamless speed control and enhanced maneuverability, particularly beneficial in varied field conditions. The front tire options (10.00-16 for 2WD or 12.4-24 for MFWD) offer flexibility for traction and terrain adaptability, while the rear tires (16.9-34) ensure sufficient load-bearing capacity and stability for heavy implements. When considering this tractor, note the 2WD model may struggle on inclines or muddy conditions compared to the MFWD variant, which offers improved traction.

DIMENSIONS & TIRES
The International Harvester Hydro 85 features a wheelbase of 88.2 inches, which contributes to enhanced stability during field operations, particularly when towing or plowing. Its front tires (10.00-16) offer maneuverability, while the larger rear tires (16.9-34) provide improved traction and weight distribution for heavy loads, making it suitable for larger agricultural tasks. However, the wide rear tire size may present challenges in narrower pathways or limited-space fields, necessitating careful navigation in tight conditions.
