Engine Displacement:
Typically around 240 cubic inches (approx. 3.9 Liters) for engines in this power class within the David Brown range.
Horsepower Range:
Approximately 50-60 PTO horsepower (exact figure dependent on specific engine variant and testing conditions)
Torque Characteristics:
Designed for robust low-end torque suitable for agricultural applications
Injection System:
Typically rotary or inline injection pump, manufacturer-specified (e.g., CAV, Lucas)
Gearbox Type:
David Brown's own design, often a constant mesh gearbox with multiple forward and reverse speeds (e.g., 8 forward, 2 reverse or more with a range splitter)
Optional Features:
Some models may have offered a range splitter or creeper gear option
Pto Options:
Standard rear Power Take-Off (PTO), often with 540 RPM capability
Operating Weight:
Approximately 4,500 - 5,500 lbs (2040 - 2500 kg) depending on configuration and fitted equipment
Front Axle Load:
Specification for front axle load capacity and distribution is essential for safe operation and tire selection, detailed in manual.
Rear Axle Load:
Specification for rear axle load capacity and distribution, critical for implement matching, detailed in manual.
Engine Oil Change:
Typically every 250 hours or annually, depending on operating conditions (refer to specific manual for exact intervals)
Fuel Filter Replacement:
Recommended at regular intervals, often with oil changes or as per diagnostic indicators
Engine Oil Type:
API CD or CE rated heavy-duty diesel engine oil, SAE 15W-40 or 10W-30 recommended based on ambient temperature. (Specific viscosity and API rating from manual is crucial).
Hydraulic Fluid Type:
Tractor hydraulic fluid (e.g., UTF - Universal Tractor Transmission fluid) or specified hydraulic oil. Capacity and specific type detailed in the manual.
Transmission Fluid Type:
If separate from hydraulic system, specified transmission oil (e.g., GL-4 rated gear oil).
Common Wear Items:
Clutch wear, PTO clutch engagement issues, hydraulic pump performance degradation, potential for diesel injection pump timing drift.
Electrical Reliability:
Wiring harness degradation and connection issues over time are not uncommon in older machinery.
Cooling System:
Radiator blockages or coolant leaks can occur, requiring flushing and radiator component checks.
Manufacturer Origin:
David Brown Tractors Ltd., a British agricultural machinery manufacturer
Legacy:
