Engine Family:
Typically Case IH or direct descendants of David Brown's engine designs. Common engines would be British-made diesel engines.
Displacement Range:
Engine displacements vary across the models, but generally fall within the 4.0L to 6.0L range for these heavy-duty tractors.
Injection Type:
Direct injection diesel, typically with rotary or inline fuel injection pumps.
Cylinder Count:
Likely 4-cylinder and 6-cylinder diesel engine configurations depending on the specific model (e.g., 1394/1490 might be 4-cyl, 1594/1690 might be 6-cyl).
Type:
Pressurized liquid cooling system with a radiator, fan, water pump, and thermostat.
Gearbox Type:
Manual transmission with multiple gear ratios. Common David Brown/Case IH transmissions included powershift options or synchronized gearboxes.
Powershift:
Some models may have offered a powershift or torque amplifier (TA) option, significantly enhancing operational flexibility.
Pto:
Power Take-Off (PTO) system, typically with multiple speeds (e.g., 540/1000 RPM) and a live PTO option, controlled by a clutch and lever.
Wheelbase:
Varies by model, but typically in the range of 2300mm to 2600mm for these tractor classes.
Operating Weight:
Operating weights would range from approximately 3500kg to 5000kg depending on the model and configuration.
Towing Capacity:
Not explicitly stated in the product description, but these tractors are designed for heavy agricultural towing and draft work.
Braking System:
Hydraulically actuated wet disc brakes for reliable stopping power, even under load.
Operator Protection:
Operator's station likely includes a rollover protection structure (ROPS) and seatbelts as standard or optional equipment, depending on the year of manufacture.
Lighting System:
Includes headlights, taillights, and work lights for operation in low-light conditions.
Operator Controls:
Basic mechanical controls for transmission, hydraulics, steering, and PTO. Instrumentation typically includes a tachometer, engine temperature gauge, oil pressure light, and fuel gauge.
Assist Features:
Limited to the functionality of the tractor itself; no advanced electronic driver assistance systems like modern vehicles.
Connectivity Options:
No electronic connectivity or Bluetooth/USB features. Focus is on robust mechanical and hydraulic operation.
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and oil type. Manual will provide specific intervals.
Hydraulic Filter Replacement:
Recommended every 1000-1500 operating hours or annually, whichever comes first. Manual will specify part numbers.
Air Filter Replacement:
Inspect regularly and replace as needed, typically every 250-500 operating hours or when dirty. Manual will provide specific part numbers.
Engine Oil Type:
Diesel engine oil, typically API CD or CE rated, with viscosity grades like 15W-40 or 10W-30 depending on climate.
Hydraulic Fluid Type:
Universal Tractor Transmission Oil (UTTO) or a specific hydraulic fluid approved by Case IH, with specific viscosity requirements.
Coolant Type:
Ethylene glycol-based antifreeze with corrosion inhibitors, typically a 50/50 mix with distilled water.
Common Wear Items:
Clutch wear, PTO engagement issues, hydraulic pump wear, and potential starter/alternator problems are common in tractors of this era. Fuel injection pump maintenance is also critical.
David Brown Legacy:
David Brown tractors were renowned for their durability and were particularly popular in the UK and Commonwealth countries. The acquisition by Case IH integrated their product lines and manufacturing expertise.
Production Period:
These specific models (1394, 1490, 1494, 1594, 1690) were predominantly produced during the 1980s.
Plants:
Manufacturing would have occurred at former David Brown plants and Case IH facilities, likely in the UK and potentially North America.
