            Engine Family:
        
        
            David Brown 3-cylinder or 4-cylinder diesel engine. Specific displacement not provided but typical for the era would be in the 3.0-4.5 liter range.
        
     
    
    
        
            Horsepower Range:
        
        
            Estimated 50-70 HP, typical for a tractor of this classification in the 1980s.
        
     
    
    
    
        
            Injection System:
        
        
            Likely a mechanical rotary or inline injection pump system. Specific brand (e.g., CAV, Lucas) not detailed.
        
     
 
    
    
    
        
            Transmission Type:
        
        
            Likely a constant mesh, unsynchronized or partially synchronized manual gearbox. David Brown offered various configurations, including 8-speed or 12-speed options (e.g., with a Hi-Lo splitter).
        
     
    
    
        
            Transmission Options:
        
        
            Possible variations in gear ratios or additional speed ranges.  PTO (Power Take-Off) speeds would also be a factor.
        
     
    
    
        
            Clutch:
        
        
            Dual-stage clutch likely standard for independent PTO operation.
        
     
 
    
    
    
        
            Infotainment System:
        
        
            N/A (Tractor from the era would have basic instrumentation, no infotainment system.)
        
     
    
    
        
            Driver Assistance Features:
        
        
            N/A (Tractor from the era would have basic controls, no electronic driver assistance.)
        
     
    
    
        
            Connectivity Features:
        
        
            N/A (No electronic connectivity features present.)
        
     
 
    
    
    
        
            Engine Oil Change:
        
        
            Typically every 250-500 operating hours, dependent on operating conditions.
        
     
    
        
            Transmission Oil Change:
        
        
            Approximately every 1000-1200 operating hours.
        
     
    
    
        
            Engine Oil Grade:
        
        
            Likely API CD or CE rated, SAE 15W-40 or 10W-30 (depending on climate).
        
     
    
        
            Hydraulic Fluid Type:
        
        
            Hydraulic Transmission Oil (HTO) or Universal Tractor Transmission Oil (UTTO), meeting specific David Brown specifications (e.g., DB 261).
        
     
    
        
            Coolant Type:
        
        
            Ethylene glycol-based antifreeze/coolant with corrosion inhibitors, typically a 50/50 mix with distilled water.
        
     
    
    
        
            Common Wear Points:
        
        
            Wear in the transmission synchronizers (if applicable), clutch wear, potential hydraulic pump or cylinder leaks, starter motor issues, and wear on PTO components.
        
     
    
        
            Electrical Problems:
        
        
            Corrosion on electrical connections, alternator/generator issues, wiring harness degradation over time.
