Description:
The David Brown/Case 1270, 1370, and 1570 tractors were typically equipped with robust Case-built diesel engines. Specific engine families and displacements vary across the models and potential build configurations.
Power Range Estimate:
Horsepower ratings for these models generally range from approximately 100 HP for the 1270 up to 150+ HP for the 1570, with torque figures commensurate with their heavy-duty application.
Injection Type:
Direct injection diesel, utilizing a high-pressure fuel injection pump and injectors.
Inclusion:
The 1370 and 1570 models, and potentially later versions of the 1270, were often equipped with turbochargers to enhance power and efficiency.
Type:
Most models featured a 'Power Shift' or 'Power Shuttle' transmission, offering on-the-go gear changes without clutch pedal operation for certain ranges.
Variants:
While the Power Shift was a hallmark, specific configurations might have offered different gear ratio sets or PTO drive options.
Operation:
The Power Shift clutch system allows for seamless shifting between gears, significantly improving operator efficiency and comfort during fieldwork.
General Profile:
These are large, heavy-duty agricultural tractors built for demanding farm operations, characterized by robust chassis, large tires, and substantial overall dimensions for stability and traction.
Operating Weight Estimate:
Operating weights would typically range from approximately 15,000 lbs for the 1270 to over 18,000 lbs for the 1570, excluding ballast.
General Design:
Designed for operational safety with features like ROPS (Roll-Over Protective Structure) where standard or optional, and reliable braking systems. Specific crash test ratings are not applicable to this class of equipment.
Operational Controls:
Emphasis on responsive steering, reliable brake systems, and intuitive control placement to ensure safe operation.
Protective Structure:
Likely equipped with or designed for the integration of ROPS for operator protection in the event of a rollover.
Engine Oil Change:
Typical intervals for engine oil and filter changes would be around 250 hours of operation, subject to operating conditions and oil type.
Hydraulic Fluid Change:
Hydraulic fluid and filter changes usually recommended every 1000-1200 hours, or annually, depending on usage and contamination levels.
Engine Oil:
API CD or higher specification diesel engine oil, with viscosity grade typically SAE 15W-40 or 30W, depending on ambient temperature.
Hydraulic Fluid:
Universal Tractor Transmission Oil (UTTO) or a compatible hydraulic fluid meeting Case specifications, often with a viscosity of approximately 10W-30 or similar.
Transmission Fluid:
For Power Shift transmissions, specific UTTO or powershift transmission fluid is required. Consult manual for exact Case specification number.
Common Wear Points:
Common wear points include transmission clutches (especially if operated harshly), hydraulic pump and valve pack seals, and general wear on PTO splines and bearings. Overheating due to cooling system issues is also possible.
Electrical Problems:
Older electrical systems can be prone to issues with wiring insulation degradation, contact corrosion, and starter/alternator failures. Faulty sensors or solenoids in the power shift system can also cause issues.
Critical Checks:
Regular inspection and maintenance of the cooling system (radiator, hoses, coolant), fuel filters, air filters, and lubrication points are crucial for longevity.
David Brown:
David Brown was a respected British tractor manufacturer known for robust and reliable agricultural machinery. The brand later became part of Tenneco (Case IH).
Case Integration:
The 1270, 1370, and 1570 models represent a significant part of Case's heavy-duty tractor lineup during their production era, often benefiting from engineering advancements from the David Brown acquisition.
Era:
These tractors were primarily produced during the 1970s and early 1980s, a period of significant development in agricultural mechanization.
