Engine Family Type:
Ford-designed inline diesel engines (specific displacements and configurations varied by model, typically 3-cylinder or 4-cylinder).
Horsepower Range Estimated:
Likely in the 40-65 HP range, depending on specific model and engine variant.
Torque Range Estimated:
Specific figures vary by engine, but designed for robust pulling power characteristic of the era.
Fuel Injection Type:
Typically indirect injection, with components like Bosch or CAV injection pumps.
Cooling Method:
Water-cooled, pressurized system.
Oil Type Specification:
Likely API CD or MIL-L-2104B specification for diesel engines of that era. Common viscosities would include SAE 30 or 10W-30/15W-40 depending on operating temperature.
Gearbox Type:
Manual transmission, likely with a sliding gear or constant mesh design.
Number Of Speeds:
Typically 5, 6, 8, or 10 forward speeds plus reverse, depending on the specific model and transmission option.
Optional Features:
Some models may have featured a dual-clutch or creeper gear option for very low speeds.
Clutch Type:
Dry single-plate or dual-plate clutch.
Transmission Fluid Specification:
Likely SAE 80W or 90W GL-4 gear oil. Specific Ford part numbers or equivalent would be detailed in the manual.
Wheelbase Range:
Varies by model; typically around 70-80 inches for standard row-crop configurations.
Tire Size Front:
Commonly 6.00-16 or 7.50-16.
Tire Size Rear:
Commonly 11.2-28, 12.4-28, or 13.6-28 agricultural tires.
Operating Weight Estimate:
Approximately 4,000 - 5,500 lbs (1800 - 2500 kg), depending on model and configuration.
Safety Features Era:
Tractors of this era typically lacked modern safety features like ROPS (Roll-Over Protective Structures) and seatbelts as standard. The manual would detail safe operating practices for the time.
Braking System Type:
Mechanical drum brakes or expanding shoe brakes, operated by foot pedals, often with differential braking.
Operator Station:
Open operator station with manual steering and a basic seat.
Engine Oil Change:
Typically every 100-200 operating hours, or annually, depending on usage and oil quality. Manual will specify exact intervals.
Transmission Fluid Change:
Typically every 600-1200 operating hours. Manual will provide exact intervals and procedures.
Air Filter Service:
Frequent inspection and cleaning/replacement, especially in dusty conditions (e.g., daily or weekly checks).
Engine Coolant:
A mix of clean water and a suitable anti-freeze/anti-corrosion additive appropriate for cast iron engines of that era.
Hydraulic Fluid:
Ford M2C41B (or later compatible fluids like M2C134A/D), often a multi-purpose tractor hydraulic fluid with good cold-weather performance and seal compatibility. Specific viscosity would be detailed.
Common Wear Items:
Clutch wear, seal leaks (engine, transmission, hydraulics), injector pump calibration drift, cooling system leaks, starter and generator wear.
Electrical Reliability:
Wiring insulation degradation over time, generator/regulator issues, and battery charging problems can occur.
Ford Tractor Division:
Ford was a dominant force in tractor manufacturing, known for its innovation and reliability, particularly with its 'Golden Jubilee' and subsequent models.
New Holland Integration:
Ford tractors were often marketed and serviced under the Fordson and later Ford New Holland branding, representing a significant lineage in agricultural machinery.
Manufacturing Locations:
Primarily manufactured in North America (USA) and potentially the UK for certain markets.
Brand Reputation In Era:
Ford tractors of this period were highly regarded for their durability, power, and innovative features (like the Select-O-Speed transmission on some models not explicitly listed but relevant to the era) and were market leaders.
Industry Impact:
These models were instrumental in the mechanization of agriculture during the post-war boom, contributing significantly to increased farm productivity.
