Precise engine identification would require serial number lookup. Performance Horsepower Range: Typically in the 30-40 PTO horsepower range. Exact figures vary based on engine option (gasoline or diesel). Torque Characteristics: Designed for good lugging ability at lower RPMs, characteristic of agricultural diesel engines of the era. Fuel System Carburetor Or Injection: Gasoline models would feature a carburetor (e.g., Zenith, Stromberg). Diesel models would utilize a direct injection fuel system with a rotary or inline injection pump (e.g., Bosch, CAV). Fuel Type Engine Fuel Type: Gasoline or Diesel, depending on the specific tractor configuration. 🔧 Transmission Standard Transmission Type: Likely a constant mesh manual transmission with multiple forward speeds and one reverse (e.g., 6-speed, 8-speed, or 10-speed options). Optional Optional Transmission Features: Possibility of a multi-power or shuttle-shift option on some Series II models for enhanced forward/reverse functionality. Features Power Take Off Pto: Standard rear PTO (540 RPM) and potentially a live PTO or independent PTO system. 📐 Dimensions Exterior Wheelbase: Approx. 75-80 inches (190-203 cm), varies slightly with tire size. Weights Operating Weight: Approximately 3,500 - 4,500 lbs (1588 - 2041 kg), depending on configuration and attached equipment. 🛡️ Safety Features Ratings Safety Standards: No formal crash ratings for tractors; safety pertains to operational stability, braking effectiveness, and guarding of moving parts as per contemporary standards. Active Features Braking System: Typically mechanical drum brakes on the rear axle, or possibly inboard wet disc brakes on later or more advanced versions. Handbrake for parking. Passive Features Operator Protection: Basic operator controls, fenders to prevent thrown debris, rear view mirrors on some configurations. Rollover Protective Structures (ROPS) were not standard but often available as an aftermarket or factory option later in its production life or for Series II models. 💡 Technology Features Infotainment Infotainment System: None. Designed for pure utility functionality, not entertainment. Driver Assistance Driver Assistance Features: None. Basic mechanical controls for operation. Connectivity Connectivity Options: None. 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 50-100 operating hours, depending on operating conditions and oil type used. Refer to manual for exact interval and oil specification. Air Filter Service: Regular checks based on operating environment; cleaning or replacement often required...
