File Type:
Portable Document Format (PDF)
Printability:
Yes, printable. Allows for individual page printing to maintain clarity and avoid damage from workshop environments.
Binding:
N/A (Digital PDF format)
Paper Quality Recommendation:
N/A (Digital PDF format). Recommend printing on durable paper for workshop use.
Engine Displacement:
Typically around 3.8 Liters (exact specification depends on specific 1194 engine variant and bore/stroke configurations used by David Brown in that period).
Horsepower:
Generally in the range of 50-60 PTO horsepower (Power Take-Off horsepower), with drawbar horsepower slightly lower. Specific figures vary by engine tune and model year.
Injection System:
Likely Lucas- CAV or similar mechanical injection pump and injectors, typical for tractors of this era.
Gearbox Type:
Constant mesh gearbox with multiple forward and reverse gears. Often featured a range selector (e.g., High/Low) and a creeper gear option on some variants.
Power Take Off Pto:
Standard 540 RPM PTO, with potential for a 1000 RPM option on some models or configurations. May include a dual-speed PTO.
Clutch Type:
Dual-clutch (live PTO clutch) or single-stage clutch depending on the specific 1194 variant. The live PTO system allows independent operation of the PTO while engaging the transmission.
Rollover Protection:
Original models may not have had ROPS (Roll-Over Protective Structure) as standard. Later regulations and aftermarket options would be relevant. The manual would detail any factory-fitted safety features.
Braking System:
Hydraulic disc brakes on rear wheels, and often mechanical or hydraulic drum brakes on front wheels (depending on 2WD/4WD configuration). Differential lock for improved traction.
Seatbelts:
May be an optional or later fitted feature; manual would cover installation and checks if applicable.
Instrumentation:
Basic dashboard instrumentation including engine temperature gauge, oil pressure gauge, ammeter, tachometer, and hour meter. Warning lights for critical functions.
Draft Control:
Mechanical draft control and position control for the 3-point hitch system, allowing precise depth control of mounted implements.
Electrical System Voltage:
Typically 12-volt electrical system.
Engine Oil Change:
Typically every 250-500 operating hours, or annually. Specific interval depends on operating conditions and oil type used. Refer to manual for exact schedule.
Transmission Oil Change:
Typically every 1000-2000 operating hours. Refer to manual for specific interval and procedure.
Engine Oil Type:
API CD or CE rated SAE 15W-40 or 10W-30 diesel engine oil. Specific viscosity dependent on ambient operating temperature. Consult manual for precise recommendations.
Transmission Hydraulic Fluid:
Farm-specific Universal Tractor Transmission Oil (UTTO) or a suitable multi-purpose tractor hydraulic fluid. Specifications for SAE viscosity and API classification will be detailed in the manual.
Coolant Type:
Ethylene Glycol based antifreeze mixed with water (typically 50/50 ratio) to provide freeze and corrosion protection. Green or amber coolants compatible with heavy-duty diesel engines.
Brake Fluid:
DOT 3 or DOT 4 hydraulic brake fluid, depending on the system. Manual will specify the correct type for the braking system.
Common Wear Points:
Potential wear in steering components, clutch wear, hydraulic system leaks (seals, hoses), PTO clutch adjustments, and common diesel engine issues like injector wear or cylinder head gasket leaks over extensive use.
Oil Filter Part Number:
Requires sourcing a compatible filter for the specific engine variant. Aftermarket cross-reference data is often available but the manual is the primary source for OEM part numbers or equivalent specifications.
Fuel Filter Part Number:
Requires sourcing a compatible filter for the specific engine variant. Aftermarket cross-reference data is often available but the manual is the primary source for OEM part numbers or equivalent specifications.
Manufacturer History:
David Brown Tractors was a British manufacturer known for robust and reliable agricultural machinery, operating from the mid-20th century. It was eventually acquired by Tenneco, which later integrated it into Case IH.
1194 Context:
The 1194 was part of David Brown's 30 and 40 Series tractors, representing a significant step in their tractor development with more advanced features and improved comfort for the operator. It was a popular model in its class.
Production Period:
The 1194 model was produced during the late 1970s and early 1980s.
