Displacement: Approximately 3.3 liters (203.6 cubic inches) for the AD4.204 engine. Performance Horsepower: Typically in the range of 55-65 PTO horsepower, depending on exact configuration and testing. Torque: Specifications vary, but generally designed for robust torque delivery at lower RPMs. Fuel System Fuel Type: Diesel Fuel Injection System: Likely a rotary or inline injection pump system (e.g., CAV or Lucas/Simms). Lubrication Oil Type: API CD or CE rated diesel engine oil, SAE 30 or 15W-40 recommended depending on climate. Oil Capacity: Approximately 7.0-8.0 liters (e.g., 7.5 US Quarts) including filter. Precise capacity will be in manual. Cooling System Coolant Type: Ethylene glycol based antifreeze with corrosion inhibitors. Coolant Capacity: Approximately 10-12 liters (e.g., 10.5-12.5 US Quarts). Precise capacity will be in manual. 🔧 Transmission Standard Gearbox Type: Constant mesh, sliding gear transmission. Gear Selection: Typically a 10-speed or 12-speed gearbox (e.g., 8 forward + 2 reverse, or 12 forward + 4 reverse with splitter). Specific configuration for 'N' variant needs manual confirmation. Optional Power Take Off: Standard 540 RPM PTO, potentially with a 1000 RPM option on some later models. Features Clutch: Dry single or dual-stage clutch. Fluid Specifications Transmission Oil Type: API GL-4, SAE 80W/90 gear oil for transmission and final drives. Some hydraulic systems may share this fluid, others may use UTF (Universal Tractor Fluid). Fluid Capacity Transmission Oil Capacity: Refer to manual for specific capacity, typically around 18-20 liters (e.g., 19-21 US Quarts) for transmission and rear axle. 📐 Dimensions Exterior Wheelbase: Approximately 76-78 inches (1930-1981 mm). Specific to 'N' variant. Length: Varies, typically around 130-140 inches (3302-3556 mm) with standard linkage. Width: Varies based on rear axle track setting, generally 70-80 inches (1778-2032 mm). Weights Operating Weight: Approximately 5000-6000 lbs (2268-2722 kg) without ballast. 🛡️ Safety Features Ratings Safety Standards: Designed to meet standards of its production era, focusing on operator protection through structural integrity and functional controls. Modern ROPS/FOPS not standard on original models but often retrofitted. Active Features Braking System: Mechanical drum brakes or hydraulic disc brakes on rear wheels, often with independent parking brake. Passive Features Operator Station: Open operator station. Manual will detail seat safety, control placement, and pedal design for safe operation. 💡 Technology Features Infotainment Features: As a tractor from its era, infotainment features are non-existent. Focus is on functional controls for farming operations. Driver Assistance Features: No electronic driver assistance features. Operation relies on mechanical controls and operator skill. Connectivity Features: No digital connectivity features. PTO and hydraulic linkages are the primary means of 'connectivity' to implements. 🔧 Maintenance Service Intervals Engine Oil Change: Typically every 100-150 operating hours or annually. Fuel Filter Replacement: Recommended at every oil change or as needed if experiencing fuel issues. Air Filter Cleaning/Replacement: Service dry-type air filter element at regular intervals (e.g., daily or weekly depending on dust conditions). Oil-bath type requires more frequent servicing. Transmission Oil Change: Typically every 500-1000 operating hours or every 1-2 years. Fluid Specifications Hydraulic Oil Type: If separate from transmission, likely...
