Estimated Page Count:
While specific page counts are not provided, a comprehensive collection of three factory manuals (Service, Shop, Parts) for a tractor of this complexity would typically range from 800 to 1500+ pages collectively, reflecting detailed coverage.
Engine Model:
David Brown 4-cylinder diesel (specific model number may vary based on production era, often derived from the AD4.203 or similar Perkins variants used by David Brown)
Engine Type:
Naturally aspirated, liquid-cooled, four-stroke diesel
Displacement:
Approximately 3.9 liters (236 cubic inches)
Horsepower Rated:
Typically around 60-70 PTO horsepower (exact figures vary by model year and specific engine tune)
Torque:
Substantial torque for pulling power, specific figures depend on engine variant.
Injection System:
Inline injection pump (e.g., Lucas CAV or similar)
Fuel Filter:
Spin-on type, specific part numbers available in the manual.
Transmission Type:
Constant mesh gearbox with synchronized or unsynchronized shifting
Number Of Gears:
Typically 8 forward and 2 reverse gears (or variations thereof, depending on specific configurations).
Optional Transmission:
Some models may have featured a creeper gear option or enhanced PTO configurations.
Clutch:
Dual-stage clutch for independent PTO operation and transmission engagement.
Pto Options:
Live PTO or ground-speed PTO, depending on the specific model variant. Standard 540 RPM PTO output.
Rear Axle Differential Lock:
Differential lock engagement mechanism for improved traction.
Engine Oil Change:
Typically every 250 hours or annually. Specific recommendation in the manual.
Air Filter Cleaning Replacement:
Inspect every 50 hours, clean or replace as needed. More frequent in dusty conditions.
Fuel Filter Replacement:
Replace every 250-500 hours, or if fuel system issues arise.
Hydraulic Fluid Filter Replacement:
Refer to manual for specific intervals, typically 500-1000 hours or as indicated by pressure checks.
Engine Oil Type:
API CD or higher, SAE 15W-40 or 10W-30 recommended (check manual for specific viscosity based on ambient temperature).
Engine Oil Capacity:
Approximately 8-9 quarts (7.6-8.5 liters) with filter change.
Hydraulic Transmission Fluid:
Case IH Hy-Tran Plus, or equivalent UTF (Universal Tractor Transmission Fluid) meeting specifications. Refer to manual for exact spec.
Hydraulic Transmission Fluid Capacity:
Approximately 15-20 gallons (57-76 liters) for the entire system. Check dipstick.
Coolant Type:
Ethylene glycol-based antifreeze mixed with distilled water (50/50 ratio). Check manual for specific type and freeze protection level.
Brake Fluid Type:
DOT 3 or DOT 4 brake fluid for the clutch and brake systems if separate. Check manual for specific requirement.
Common Issues:
Wear in gearbox synchronizers, hydraulic pump output degradation over time, minor electrical connection corrosion, PTO clutch wear. Manual provides troubleshooting for these.
Preventative Maintenance:
Regular lubrication, adherence to service intervals, and inspection of hydraulic fluid and filters are key to preventing common wear-related issues.
Brand Heritage:
David Brown Tractors was a British agricultural machinery manufacturer founded by David Brown. It merged with Case Corporation in 1971, and the brand continued to be used for a period, eventually being phased out in favor of the Case IH branding.
Model Evolution:
The 1290 was part of David Brown's successful range of tractors, evolving from earlier models and contributing to the company's reputation for building strong, reliable farm machinery. It represented a step up in power and features compared to earlier generations.
Production Period:
The 1290 model was primarily produced during the 1970s and early 1980s, following the acquisition by Case.
Manufacturing Locations:
Original production likely in the UK at David Brown's factories (e.g., Meltham, Yorkshire). Post-acquisition, production may have involved Case facilities.
