Engine Type:
David Brown AD4/48 (typically, but engine variants may exist for 880 models)
Displacement:
Approx. 3.0 litres (183.7 cu. in.)
Horsepower:
Approx. 52 PTO hp (rated, actual figures may vary by specific engine tune and condition)
Torque:
Specific torque figures not readily available for parts catalogue but representative of diesel engine output for its era.
Injection System:
Typically CAV or Bosch inline injection pump with mechanical governor.
Gearbox Type:
David Brown constant mesh gearbox with Selectamatic hydraulic lift control and multi-speed PTO.
Livedrive Clutch:
Model 880/A features 'Livedrive', an independent clutch for PTO engagement while roading or operating implements.
Speed Options:
Typically 8 forward and 2 reverse speeds.
Final Drive:
Spur gear reduction at rear wheels.
Engine Oil Change:
Typically every 100-125 operating hours or annually, depending on usage severity. Refer to specific tractor manual for exact intervals.
Transmission Oil Change:
Recommended every 500-1000 operating hours. Both gearbox and rear axle often share or have separate service points.
Engine Oil Type:
API CD or CE equivalent, SAE 30 or 15W-40 for most operating temperatures. Refer to manual for precise specifications.
Transmission Hydraulic Fluid:
David Brown recommended specific hydraulic fluids or Universal Tractor Transmission Oil (UTTO) meeting certain specifications for the Selectamatic system and gearbox. Common specification is usually for an API GL-4 rated gear oil or compatible hydraulic fluid.
Engine Coolant:
Ethylene glycol-based antifreeze/coolant with rust inhibitors, mixed 50/50 with water for freeze protection and corrosion control.
Differential Oil:
Typically shared with gearbox or a separate fill. API GL-4 or GL-5 gear oil appropriate for hypoid gearing is common, but check manual for specific viscosity and formulation.
Selectamatic System:
Potential for hydraulic leaks, pump wear, and control valve issues due to age and usage. Requires proper fluid levels and filter maintenance.
Gearbox Synchromesh:
While primarily constant mesh, some wear can occur in selector forks and dog clutches over time leading to stiff shifting. Parts catalogue is vital for these components.
Engine Starting:
Glow plugs, injection timing, and fuel system integrity are critical for reliable diesel starting, especially in cold weather.
Manufacturer:
David Brown Tractors Ltd., United Kingdom.
Model Introduction:
The 880 Selectamatic was a key model in David Brown's range, introduced in the early to mid-1960s, evolving from earlier 850 and 860 models.
Production Period:
Mid-1960s to early 1970s (specific years for 880/A and 880/B may vary slightly).
Manufacturing Location:
Meltham, Yorkshire, England.
