Engine Model:
Typically a David Brown diesel engine (specific model designation might vary within 1294 series, but likely a 3 or 4-cylinder unit).
Cylinder Configuration:
Likely 3 or 4 cylinders, naturally aspirated diesel.
Horsepower Range:
Typically in the 50-70 PTO HP range, depending on specific engine variant.
Torque Characteristics:
Designed for robust low-end torque suitable for agricultural applications.
Fuel Injection:
Likely direct injection, possibly with a distributor-type or inline injection pump (e.g., CAV, Bosch).
Cooling Type:
Water-cooled, pressurized system with a radiator and fan.
Oil Type:
API CE or CF service classification diesel engine oil, viscosity typically SAE 15W-40 or 30 depending on ambient temperature.
Cylinder Head Torque:
Specific torque sequence and values for cylinder head bolts will be detailed in the manual, critical for proper sealing.
Gearbox Type:
Likely a non-synchronized constant mesh gearbox with multiple forward and reverse gears, potentially with a High/Low range selector.
Powershift Or Clutch Assist:
Some higher-spec models might have had a partial powershift or torque amplifier option, though less common for this class. Manual will specify.
Clutch Type:
Typically a dry single or dual-stage clutch for transmission engagement and PTO engagement.
Transmission Oil Type:
Manual transmission fluid (MTF) or Universal Tractor Transmission Oil (UTTO) API GL-4, SAE 80W-90 or 85W-140, or potentially a dedicated hydraulic/transmission fluid specified by David Brown.
Gear Ratio Details:
The manual will provide detailed gear ratios for all forward and reverse speeds, crucial for performance analysis and repairs.
Engine Oil Change Interval:
Typically every 250 hours of operation, but the manual will provide the precise interval based on operating conditions.
Air Filter Replacement:
Intervals are based on operating hours and dust levels, with the manual specifying visual inspection and replacement criteria.
Fuel Filter Replacement:
Recommended replacement intervals, typically tied to engine oil change intervals or as needed based on fuel quality.
Coolant Type:
Ethylene glycol-based antifreeze, mixed with distilled water. Manual will specify the correct ratio and type.
Hydraulic Fluid Type:
Dedicated hydraulic oil or UTTO (Universal Tractor Transmission Oil) meeting specific David Brown or industry specifications. Capacity will be listed in the manual.
Common Wear Items:
Clutch wear, PTO engagement issues, hydraulic leaks, and potential wear in the transmission or final drives are common, all addressed in the manual.
Electrical Gremlins:
Older wiring harnesses can degrade; the manual's wiring diagrams are invaluable for troubleshooting electrical faults.
Grease Points:
The manual will provide a comprehensive lubrication chart detailing all grease points (e.g., kingpins, steering pivots, linkage joints) and recommended grease types.
Manufacturer Origin:
David Brown Tractors was a British manufacturer with a long history in agricultural machinery, known for robust and reliable tractors.
1294 Positioning:
The 1294 was part of David Brown's later range, often considered a mid-range utility tractor, succeeding earlier models and offering enhanced features and power.
Production Period:
The 1294 model series was produced in the late 1970s and early 1980s.
Manufacturing Location:
Manufactured in Meltham, Yorkshire, England.
