Engine Type:
Diesel (specific engine variant not detailed in product info, but typical for this era of David Brown)
Engine Manufacturer Assumption:
Likely David Brown in-house or a Perkins diesel engine, common in British tractors of the period.
Horsepower Range Estimate:
Typically in the 40-60 HP range for tractors of this size and era, though specific 1412 variants would vary.
Torque Estimate:
Torque figures would be engine-specific but designed for substantial pulling power.
Injection System:
Likely mechanical injection, with details for pump and injector servicing expected in the manual.
Transmission Type:
Manual (likely a multi-speed gearbox with high/low range options common to David Brown tractors)
Optional Features:
Specific optional transmissions not detailed, but some models may have offered variations.
Clutch Type:
Typically a single or dual-stage dry clutch for agricultural tractors of this era.
Gear Ratios:
Detailed gear ratio information for all forward and reverse gears would be present.
Overall Length:
Varies by specific 1412 configuration, but generally compact to medium-sized tractor dimensions.
Overall Width:
Designed for standard row spacing and field work, width would be moderate.
Wheelbase:
Specific wheelbase dimensions would be provided in the manual for alignment and geometry checks.
Operating Weight:
Typically in the range of 4,000 - 6,000 lbs (1800 - 2700 kg) depending on configuration and ballast.
Front Axle Load:
Information for front axle load capacity and distribution would be detailed.
Rear Axle Load:
Information for rear axle load capacity and distribution would be detailed.
Rollover Protection Structure Rops:
ROPS availability or retrofitting information might be covered, depending on the era and original specification.
Braking System Type:
Typically wet disc or drum brakes, with detailed service procedures.
Seatbelt Availability:
Seatbelt information or recommendations might be included.
Engine Oil Change:
Typically every 100-250 operating hours, specific recommendation in manual.
Hydraulic Fluid Change:
Annual or every 500-1000 operating hours, specific recommendation in manual.
Air Filter Replacement:
As needed, based on operating conditions, with specific checks and replacement intervals provided.
Engine Oil Type:
API CD/CE rated diesel engine oil, viscosity grade like 15W-40 or 20W-50 depending on ambient temperature. Exact spec in manual.
Hydraulic Fluid Type:
Tractor hydraulic fluid (THF) or universal tractor transmission oil (UTTO) meeting appropriate specifications. Likely referencing Ford/New Holland M2C134-D or similar.
Coolant Type:
Ethylene glycol based antifreeze with corrosion inhibitors, typically a 50/50 mix with water.
Common Wear Points:
Wear in PTO clutch, hydraulic pump, and common electrical connection corrosion are typical for older tractors.
Engine Related:
Potential issues with injector pump timing, glow plug reliability, and exhaust leaks common to older diesel engines.
Transmission Related:
Wear on transmission gears, synchronizers, and clutch packs if not properly maintained.
Manufacturer:
David Brown Tractors Ltd., a historic British manufacturer of agricultural machinery.
David Brown Tractor Lineup:
The 1412 is part of a lineage of robust and reliable tractors produced by David Brown, known for their sturdy construction and practical design.
Production Period Estimate:
David Brown tractors were produced from the mid-20th century. The 1412 model likely falls within the 1970s or 1980s production era, though exact dates would require further research.
