Petrol Engine Variants: Likely to cover BMC's overhead valve (OHV) petrol engines, potentially derived from Austin or Morris car engines (specific displacement varies by Mini Tractor model). Performance Horsepower Range: Typically in the 15-35 HP range, depending on the specific engine and model variant. Torque Characteristics: Designed for consistent torque delivery at lower RPMs, crucial for farm work. Fuel System Diesel Fuel System: Direct injection, typically with rotary or inline injection pumps (e.g., CAV, Simms) and glow plug starting assistance. Petrol Fuel System: Carbureted, with typical ignition systems employing distributors and coils. Lubrication Oil Type Diesel: API CD or equivalent multi-grade diesel engine oil (e.g., SAE 15W-40, SAE 20W-50 depending on temperature and specific engine recommendation). Oil Type Petrol: API SF/CD or equivalent multi-grade gasoline engine oil (e.g., SAE 10W-30, SAE 20W-50). Cooling System Cooling Medium: Water-cooled, pressurized system with thermostat and fan. Coolant Type: Ethylene glycol based antifreeze coolant with corrosion inhibitors. Transmission Standard Gearbox Type: Manual transmission, typically a constant mesh gearbox with multiple forward and reverse gears. Features Gear Selection: Synchromesh may be present on higher gears, depending on the specific model and production year. Power Take Off Pto: Independent or transmission-driven PTO, often with multiple speed options (e.g., 540 RPM). Fluid Specifications Transmission Fluid Type: API GL-4 or GL-5 multi-purpose gear oil (e.g., SAE 80W-90, SAE 90). Differential And Axles Rear Axle Fluid: Similar to transmission fluid specifications (API GL-4/GL-5 SAE 80W-90). Dimensions Exterior Wheelbase: Varies by model, typically compact for maneuverability. Weights Operating Weight: Ranges from approximately 1000-1500 kg (2200-3300 lbs) depending on configuration. Towing Capacity: Designed for light-duty towing, specific capacity varies by model and braking system. Safety Features Ratings Rollover Protection: ROPS (Roll Over Protective Structure) may be an optional or standard fitment on later models or depending on market regulations. The manual would cover installation and maintenance if present. Active Features Braking System: Typically mechanical drum brakes or early hydraulic disc/drum brakes, with independent rear wheel braking and potentially parking brake. Passive Features Operator Station: Basic operator controls, seat, and potentially safety guards for PTO and other moving parts. Technology Features Infotainment Infotainment System: N/A (Basic agricultural equipment with no...
