Engine Manufacturer:
David Brown (likely a Perkins engine variant, common for the era and brand)
Displacement:
Typically in the range of 3.5 to 4.0 liters (specific to engine variant, e.g., 3.18L or 3.92L for Perkins models).
Horsepower Range:
Approximately 70-85 PTO horsepower (Power Take-Off horsepower), depending on specific engine tune and model variant.
Torque Curve:
Detailed torque specifications and potential ranges available within the manual for engine components.
Injection System:
Direct injection, likely utilizing a rotary or inline injection pump (e.g., CAV, Bosch).
Cooling Type:
Water-cooled
Oil Capacity:
Refer to manual for specific oil capacity, typically around 8-10 liters.
Overall Length:
Refer to manual for precise dimensions, typically around 3.5-4.0 meters.
Overall Width:
Refer to manual for precise dimensions, typically around 1.8-2.0 meters.
Operating Weight:
Typically in the range of 3,500 - 4,500 kg (unladen).
Drawbar Pull Capacity:
Detailed in manual, significant for tractor operation.
Infotainment Systems:
Basic tractor instrumentation including engine temperature gauge, oil pressure warning light, ammeter, and tachometer. No advanced infotainment features.
Driver Assistance Features:
Primary driver assistance is the mechanical linkage and hydraulic assist for steering and implement control. No electronic driver aids.
Connectivity Options:
N/A. This is a mechanical tractor from an era preceding modern vehicle connectivity.
Engine Oil Change:
Typically every 250-500 operating hours, refer to manual for precise interval and oil type.
Air Filter Maintenance:
Frequent checks and cleaning, replacement as needed based on operating conditions. Specific interval in manual.
Fuel Filter Replacement:
Scheduled replacement based on hours of operation, typically every 250-500 hours. Manual will specify.
Engine Oil Type:
Typically API CD or CE rated diesel engine oil, viscosity grade SAE 15W-40 or 10W-30 depending on ambient temperature. Manual is definitive.
Hydraulic Transmission Fluid:
David Brown specialized UTF (Universal Tractor Transmission Fluid) or equivalent. Manual will specify exact type and specifications (e.g., API GL-4).
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors. Refer to manual for specific mix ratio and type.
Common Wear Parts:
Clutch wear, hydraulic pump performance degradation, front axle kingpin wear, and potential seal leaks are common areas of focus in this model range.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical issues. Manual's wiring diagrams are crucial for diagnosis.
Pto Engagement:
Issues with PTO engagement or disengagement can arise from linkage wear or internal clutch pack issues, detailed in the manual.
