Engine Make Model:
David Brown (various diesel engines, often manufactured by the company itself or sourced from reputable diesel engine builders).
Displacement And Configuration:
Typically 4-cylinder diesel engines. Specific displacement varied by exact model variant and year, commonly in the range of 3.5 to 4.5 liters (e.g., 212ci for some variants).
Horsepower Range:
Approximately 50-65 PTO horsepower, with drawbar horsepower slightly lower.
Torque Characteristics:
Designed for strong low-end torque, crucial for pulling heavy loads and operating at lower engine speeds.
Injection System:
Typically rotary or inline injection pumps (e.g., CAV or Bosch).
Gearbox Type:
Constant mesh, non-synchronized manual transmission.
Gear Configuration:
Commonly 10 forward and 2 reverse gears, or 8 forward and 2 reverse depending on the specific model/options.
Dual Clutch System:
Often featured a dual-clutch system allowing for engagement of the PTO without disengaging the transmission.
Pto Options:
Independent Power Take-Off (PTO) typically with 540 RPM standard.
Differential Lock:
Typically equipped with a foot-operated differential lock for enhanced traction in slippery conditions.
Wheelbase:
Approx. 80-84 inches (203-213 cm), depending on variant.
Overall Length:
Approx. 120-130 inches (305-330 cm), excluding implement.
Overall Width:
Approx. 65-75 inches (165-190 cm) at rear axle, adjustable.
Operating Weight:
Around 5,000-6,000 lbs (2,270-2,720 kg) without ballast or implements.
Engine Oil Change:
Typically every 100-150 operating hours, or annually. (Specific interval depends on oil type and operating conditions).
Greasing:
Daily or weekly greasing of pivot points, kingpins, and PTO shaft spline is crucial.
Engine Oil Type:
API CD or CE rated diesel engine oil, SAE 15W-40 or 10W-30 depending on climate. (Refer to manual for exact specification).
Transmission Hydraulic Fluid:
Universal Tractor Transmission Oil (UTTO) or equivalent, typically 10W-30 or 134D fluid type. Capacity around 10-12 gallons (38-45 liters).
Coolant:
Ethylene glycol based antifreeze mixture, typically 50/50 with distilled water for freeze and corrosion protection.
Final Drive Oil:
Typically shares the same UTTO fluid as the transmission and hydraulic system. Capacity varies per side.
Common Wear Points:
Steering box wear, clutch wear, hydraulic pump performance degradation over time, potential for oil leaks from seals and gaskets.
Fuel System Maintenance:
Regular cleaning or replacement of fuel filters is essential due to potential diesel fuel contamination.
Cooling System Maintenance:
Regular flushing and refilling of the cooling system, checking for radiator leaks and thermostat function.
Parts Considerations:
While original parts may be scarce, many common wear items and filters are still available from aftermarket suppliers specializing in vintage tractors.
David Brown Legacy:
David Brown Tractors Ltd. was a British manufacturer known for its robust and reliable agricultural machinery, later becoming part of Case IH.
Series Development:
The 990 and 995 were part of a successful line of tractors that evolved from earlier David Brown designs, offering improved features and power.
Production Years:
The 990 series was produced roughly from the early 1960s to the mid-1970s, with the 995 being an update or variant within this period.
