Engine Options:
Available with International Harvester's own diesel engines (e.g., D-236, D-282, DT-282) and potentially gasoline variants.
Diesel Displacement Examples:
D-236: 236 cu. in. (3.87 L); D-282: 282 cu. in. (4.62 L)
Diesel Horsepower Range:
Typically in the 60-80 PTO horsepower range, depending on specific engine and tuning.
Injection Type:
Direct injection for diesel models, often featuring Roosa-Master or similar rotary injection pumps.
Fuel Type:
Diesel Fuel (CD-15 or equivalent) for diesel variants; Gasoline for gasoline variants.
Oil Type Recommendation:
Refer to manual for specific API service classification (e.g., API CC/CD or later equivalent for diesel engines) and viscosity grades (e.g., SAE 10W-30, 15W-40).
Coolant Type Recommendation:
Ethylene Glycol based antifreeze mixed with distilled water (typically 50/50 ratio). Manual will specify exact formulation and capacity.
Transmission Type:
T-34 or T-35 manual transmission with 10 forward and 2 reverse speeds (range transmission).
Powershift Availability:
Optional Power-Shift transmission available on some models.
Pto Options:
540 RPM and 1000 RPM PTO options, often independent or non-live.
Gear Ratio Information:
Detailed gear ratio charts for all speed ranges will be present in the manual.
Transmission Fluid Type:
IH Hy-Trans fluid or equivalent (e.g., JD-Q82, Ford M2C41-A, etc.). Manual will confirm specific IH part number or interchange.
Wheelbase:
Approximately 90 inches (2286 mm) for 2WD models.
Length:
Varies by configuration, typically around 130-140 inches (3300-3550 mm).
Operating Weight:
Approximately 6,000 - 8,000 lbs (2720 - 3630 kg), depending on configuration and options.
Drawbar Pull Capacity:
Capable of significant drawbar pull, specified by tractor weight and traction. Manual will provide specific ratings.
Roll Over Protection System:
ROPS (Roll Over Protective Structure) may be an option or field-installed. Manual will detail any certified ROPS installations and requirements.
Brake System:
Mechanical disc brakes or expanding shoe brakes, typically internal to the rear axle housing. Maintenance and adjustment procedures covered.
Operator Station:
Designed for operator comfort and safety, with controls positioned for ease of use. Manual will detail safety precautions for operation.
Era Appropriateness:
Tractor from an era where infotainment was non-existent. Focus is purely on operational mechanics and PTO/hydraulic power.
Instrumentation:
Basic dashboard instruments including tachometer, oil pressure gauge, coolant temperature gauge, ammeter/voltmeter, and fuel gauge.
Connectivity Features:
Not applicable for this era of tractor.
Engine Oil Change:
Typically every 100-200 operating hours, depending on operating conditions. Manual will provide precise recommendations.
Transmission Fluid Change:
Usually at 600-1200 operating hours or annually. Manual will specify exact interval.
Hydraulic Fluid Change:
Similar to transmission fluid, often at 600-1200 operating hours. Manual will provide details.
Engine Oil Capacity:
Varies by engine, e.g., D-282 approximately 9 quarts (8.5 L) with filter. Manual to confirm.
Transmission Hydraulic Capacity:
Varies by transmission type (e.g., 10-speed vs. Power-Shift), typically around 18-20 gallons (68-76 L). Manual to confirm.
Engine Coolant Capacity:
Approximately 16-18 quarts (15-17 L). Manual to confirm.
Common Wear Items:
