⚙️ Engine Specifications

Engine Model:

Likely a Perkins AD3.152 or similar diesel engine, common in this era of IH tractors.

Engine Type:

3-Cylinder Diesel

Displacement:

Approximately 152 cu. in. (2.5 Liters) - based on common engine variants for the 474.

Horsepower Rating:

Typically around 47-50 PTO horsepower (actual engine HP slightly higher).

Torque Rating:

Specific torque figures are model-dependent but designed for substantial low-end torque for agricultural work.

Fuel Type:

Diesel

Injection System:

Direct injection, likely with a rotary or inline injection pump (e.g., Simms, CAV, or Lucas).

🔧 Transmission

Transmission Type:

8-speed manual transmission (4 forward gears, 2 reverse gears in two ranges: high and low).

Optional Transmission:

Likely a 'Synchronized' version for easier shifting. Hydrostatic transmission not typically offered on the 474.

Clutch Type:

Dual-stage clutch (one for transmission, one for PTO).

Pto Speed:

Standard 540 RPM PTO, potentially with a 1000 RPM option or dual speed PTO depending on configuration.

📐 Dimensions

Wheelbase:

Approximate wheelbase of 72 inches (1829 mm).

Operating Weight:

Approximately 4,500 - 5,000 lbs (2041 - 2268 kg) depending on configuration and ballast.

🛡️ Safety Features

Safety Standards:

Designed to meet agricultural safety standards of its production era. Roll Over Protection Structure (ROPS) and seatbelts may be optional or dealer-installed upgrades, not always standard from factory depending on year and market.

Braking System:

Mechanical/hydraulic assisted brakes.

Operator Station:

Open operator station (platform) or optional cab, designed for operator visibility and control.

💡 Technology Features

Infotainment System:

N/A (This is a utility tractor from the late 70s/early 80s; no infotainment systems were present).

Driver Assistance Features:

N/A (Basic operator controls for steering, throttle, and transmission are the primary features).

Connectivity Options:

N/A

🔧 Maintenance

Engine Oil Change:

Typically every 250 hours of operation or annually. Specific oil type and viscosity are critical.

Fuel Filter Replacement:

Recommended every 250-500 hours or as needed based on fuel quality.

Air Filter Service:

Service based on operating conditions (dusty environments require more frequent cleaning/replacement).

Hydraulic Fluid Change:

Typically every 1000 hours or biennially. Filter replacement is also critical.

Engine Oil Specification:

API CD or CE rated diesel engine oil, SAE 15W-30 or 10W-30 depending on ambient temperature. Consult manual for exact specifications.

Hydraulic Fluid Specification:

IH Hy-Tran fluid or equivalent UTF (Universal Tractor Transmission) fluid. Capacity approx. 10-12 gallons.

Coolant Specification:

Ethylene glycol-based antifreeze mixed with distilled water (50/50 ratio). Capacity approx. 10-12 quarts.

Common Problems:

Wear in transmission synchronizers (if equipped), hydraulic lift system leaks, injector pump timing drift, starter motor issues, potential for radiator leaks and hose degradation.

Maintenance Recommendations:

Regular greasing of pivot points, checking and topping up all fluid levels, proper air cleaner maintenance, and ensuring the fuel system is free from water and sediment are crucial for longevity.

📚 Vehicle History

Brand Legacy:

International Harvester (IH) was a major American manufacturer of agricultural and construction equipment, known for its durable and reliable tractors.
