Model Variant Coverage:
International Harvester 424 Tractor
Engine Type:
Inline Diesel (likely variations of International Harvester's C-series or BD series engines, specific model to be detailed in manual)
Engine Displacement:
Likely in the range of 144 to 236 cubic inches (2.36L to 3.87L), depending on specific engine variant (e.g., C153, BD-154, BD-206, BD-236). Actual manual will confirm.
Horsepower:
Variable based on engine and configuration, typically in the 40-65 PTO HP range. Specific figures will be in the manual.
Torque:
Specific torque figures will be detailed in the manual.
Injection System:
Likely mechanical injection (e.g., CAV, Simms, or Bosch distributors/pumps). Manual will specify.
Cooling Type:
Water-cooled
Transmission Type:
Manual Synchromesh Transmission (likely 8-speed or 10-speed options based on IH's typical offerings for this era).
Transmission Type:
Possible options like a range splitter or independent PTO, though a separate 'Automatic Transaxle System' is listed, which might refer to a specialized gearbox or torque converter setup not common on tractors of this class, or it could be a miscategorization in the product description. Standard transmissions were typical.
Gear Ratios:
Detailed gear ratios for forward and reverse gears will be in the manual.
Power Takeoff Pto:
Likely independent PTO, specification for speeds (e.g., 540 RPM) and engagement method will be covered.
Wheelbase:
Specific dimensions will be in the manual; typical for a utility tractor of this size, likely around 75-80 inches.
Operating Weight:
Approximately 3500-4500 lbs, depending on configuration. Manual will provide exact weights.
Towing Capacity:
Towing capacity not typically stated as a specification for tractors, but drawbar pull capabilities will be implied by engine power and traction. Manual will offer guidance.
Safety Features:
The manual will detail safety warnings and procedures. Tractor safety standards of the era were less stringent than modern vehicles. Features may include brake interlocks, PTO shields, and operator presence controls. Modern ROPS (Roll Over Protective Structures) were not standard but may be covered if an aftermarket option is referenced.
Active Safety:
Brake systems, steering system functionality.
Passive Safety:
Operator controls, shielding of moving parts.
Engine Oil Change:
Typically 100-250 hours or annually, depending on operating conditions. Manual will provide precise intervals and oil type.
Transmission Fluid Change:
Intervals vary significantly based on fluid type and service. Manual will specify, likely around 500-1000 hours.
Hydraulic Fluid Change:
Similar to transmission fluid, intervals will be specified in the manual.
Engine Oil Specification:
Likely a high-quality diesel engine oil, such as API CD or CE rated, with a viscosity grade like SAE 15W-40 or 30W, depending on ambient temperature. Manual will specify the exact IH-approved grade.
Transmission Fluid Specification:
Often a Universal Tractor Transmission Oil (UTTO) or specific IH hydraulic fluid. Manual will list the exact part number or specification.
Hydraulic Fluid Specification:
Typically the same as transmission fluid (UTTO) or a specific IH hydraulic fluid. Manual will confirm.
Coolant Specification:
A mixture of ethylene glycol and water, with specific anti-corrosion additives. Manual will specify the type and ratio.
Common Wear Items:
Clutch wear, injector pump timing issues, hydraulic pump wear, starter motor issues, and potential fuel system leaks are common for tractors of this age. The manual will provide diagnostic and repair procedures for these.
Fuel Filter Part Number:
Specific part numbers for fuel, oil, and air filters will be in the manual, crucial for correct maintenance.
Oil Filter Part Number:
Specific part numbers for fuel, oil, and air filters will be in the manual.
Air Filter Part Number:
Specific part numbers for fuel, oil, and air filters will be in the manual.
Brand:
International Harvester (IH), a major American manufacturer of agricultural and construction equipment with a long history.
Model Context:
The 424 was part of IH's successful utility tractor lineup, produced during the mid-to-late 1960s. It offered a balance of power, versatility, and affordability for small to medium-sized farms.
Production Years:
Approximately 1965-1967. Specific production dates and locations (likely Louisville, KY) will be implied by the manual's context.
