Print Readability:
Designed for clear digital viewing and printing of individual pages or sections. Original factory print quality is a benchmark.
Binding For Physical Copy:
Not applicable as product is in PDF format. Original manuals would have been professionally bound for workshop use.
Paper Type For Physical Copy:
Not applicable as product is in PDF format. Original manuals would have been printed on durable, often heavy-weight paper suitable for workshop environments.
Engine Make Model:
David Brown 4-cylinder diesel engine (specific model designation may vary, often a variant of the AD4.248 or similar Perkins-derived engine used by David Brown).
Horsepower Rating:
Typically in the range of 70-80 PTO horsepower (exact rating subject to specific engine configuration and model year).
Engine Displacement:
Approximately 240-250 cubic inches (around 4.0 liters).
Injection System:
Typically Lucas or CAV fuel injection pump and injectors.
Transmission Type:
Constant mesh gearbox with 12 forward and 4 reverse gears (or similar configuration).
Optional Transmission Features:
May include creeper gears or enhanced PTO options depending on specific configuration.
Pto Options:
Standard 540 RPM and 1000 RPM PTO options were common.
Tractor Instrumentation:
Basic instrumentation typically includes tachometer, oil pressure gauge, coolant temperature gauge, fuel gauge, and warning lights for charging and other critical functions. No advanced infotainment systems.
Tractor Safety Features:
Features like ROPS (Roll-Over Protective Structure) might be an option or standard depending on regional regulations and specific configuration. PTO shields and safety interlocks are crucial.
Engine Oil Change Interval:
Typically every 250 hours of operation or annually, whichever comes first. Specific oil viscosity (e.g., SAE 15W-40) would be detailed in the manuals.
Hydraulic Fluid Change Interval:
Generally every 500-1000 hours, depending on operating conditions and fluid type. The manual will specify the correct fluid type (e.g., UTF - Universal Tractor Transmission Fluid).
Engine Oil Type:
Diesel Engine Oil, API CD or higher classification, viscosity typically SAE 15W-40 or SAE 20W-50 depending on ambient temperature. Consult manual for exact specification.
Transmission Hydraulic Fluid Type:
Universal Tractor Transmission Fluid (UTF) meeting specific Case David Brown or industry standards. Capacity will be specified for gearbox and hydraulic reservoir.
Coolant Type:
Ethylene Glycol based antifreeze, typically a 50/50 mix with distilled water. Manual will specify the required freeze protection and corrosion inhibitors.
Common Wear Points:
Hydraulic system leaks, clutch wear, PTO engagement issues, front axle kingpin wear, and engine component wear (e.g., injectors, injection pump) are common maintenance considerations for tractors of this age.
Electrical System Potential Problems:
Corrosion on electrical connectors, aging wiring harnesses, and starter/alternator issues can arise over time.
David Brown History:
David Brown Tractors was a British manufacturer of agricultural machinery, known for robust and reliable tractors. The company was eventually integrated into Tenneco and then Case Corporation.
1494 Series Development:
The 1494 was part of a successful line of tractors produced by David Brown (and later Case David Brown), offering enhanced power and features over previous models. It was a popular workhorse in its era.
Production Period:
The 1494 series was primarily produced in the late 1970s and early 1980s.
