Engine Manufacturer And Model:
Likely a David Brown or Perkins diesel engine. The 1194 was commonly fitted with a David Brown 3-cylinder engine or a Perkins 3.152 (or similar displacement) diesel.
Engine Type:
Diesel, Naturally Aspirated (likely)
Cylinder Count:
3 Cylinders (common configuration for this model range)
Displacement:
Approx. 2.6 - 3.1 Liters (common for David Brown 3-cylinder diesels and Perkins 3.152 variations).
Horsepower Rating:
Typically in the 45-55 PTO horsepower range (exact rating depends on specific engine variant and tuning).
Torque Rating:
Specific torque figures vary, but designed for substantial low-end torque essential for agricultural work.
Injection System:
Direct Injection (typical for this era and engine type), likely with a rotary or inline fuel injection pump (e.g., CAV, Simms, or Bosch).
Cooling Method:
Liquid-cooled (Water-cooled)
Gearbox Type:
David Brown constant mesh gearbox, likely a 8-speed or 12-speed (e.g., CR Series gearbox common in this era). May include a creeper gear option.
Powershift Or Overspeed:
Some models may have featured a 'Grip-Shift' or similar two-speed engagement for PTO or rear axle, but full powershift was less common for this specific model designation.
Pto:
Standard 540 RPM PTO, often with a 2-speed (540/1000) option or a ground-speed PTO depending on the specific variant and market.
Differential Lock:
Mechanical differential lock, foot-pedal operated.
Wheelbase:
Specifications vary by configuration; typical for this class would be around 75-85 inches (190-215 cm).
Shipping Weight:
Estimated around 4,500 - 5,500 lbs (2,040 - 2,500 kg) unballasted.
Operating Weight:
Can exceed 6,000 lbs (2,720 kg) with ballast and operator.
Engine Oil Change:
Typically every 250-500 operating hours, or annually. Specific interval detailed in the manual.
Air Filter Service:
Check and clean/replace as needed based on operating conditions, typically every 250 hours. Manual will specify.
Engine Oil Grade:
Likely API CD or CE rated diesel engine oil, SAE 15W-40 or 10W-30 depending on climate. Manual is definitive.
Transmission Hydraulic Fluid:
Tractor Transmission Oil (TTO) or Universal Tractor Transmission Oil (UTTO) conforming to David Brown specifications. May also use SAE 90 gear oil in certain components. Manual is crucial for correct type.
Coolant:
Ethylene glycol-based antifreeze mixture for permanent antifreeze protection, typically a 50/50 mix with distilled water. Manual will specify concentration and type.
Common Wear Items:
Clutch wear, PTO clutch pack wear, hydraulic pump efficiency degradation, seal leaks (engine, transmission, hydraulics), front axle wear, electrical connection corrosion.
Potential Problems:
Overheating due to radiator blockage or thermostat failure, power loss due to fuel system issues (filters, injection pump timing), starter motor issues, difficulty shifting gears if synchronizers or shift forks are worn.
Manufacturer Origin:
David Brown Tractors was a British manufacturer, known for robust and reliable agricultural machinery.
Parent Company Evolution:
David Brown Tractors was acquired by Tenneco in 1970, becoming part of Case IH later in the 1980s/1990s.
Positioning Within Lineup:
The 1194 likely sat in the mid-range horsepower category of David Brown's tractor lineup during the 1980s, offering a balance of power and maneuverability.
Manufacturing Location:
United Kingdom
Production Period:
The '94 Series' tractors were produced from the early to mid-1980s.
