Engine Manufacturer:
David Brown (often utilizing a Perkins or similar quality diesel engine as an OEM supplier)
Engine Model Type:
Typically a 4-cylinder or 6-cylinder turbocharged direct-injection diesel engine.
Engine Displacement:
Approx. 5.7 - 6.5 Liters (depending on specific engine variant)
Rated Engine Power:
Approximately 110 - 130 PTO horsepower (Horsepower ratings can vary slightly based on specific engine tuning and testing standards).
Peak Torque:
Significant torque output for heavy draft applications, crucial for pulling implements at low speeds.
Fuel Injection Type:
Direct Injection (DI) with rotary or in-line injection pump.
Transmission Type:
12-speed or 16-speed constant mesh gearbox with synchromesh for main gears. May include a Hi-Lo splitter or powershift option.
Powershift Option:
Optional powershift transmission (e.g., 'SynchroShift') allowing gear changes without clutch operation.
Clutch Type:
Heavy-duty dual-stage clutch (for PTO and transmission engagement).
Pto Speeds:
Standard PTO speeds such as 540 RPM and 1000 RPM, with ground speed PTO often available.
Rollover Protection:
ROPS (Roll-Over Protective Structure) is standard or an option on most 1690 models, critical for operator safety.
Braking System:
Self-adjusting, sealed wet disc brakes for reliable stopping power in all conditions.
Lighting:
Integrated lighting system for safe operation in low light and at night.
Seatbelts:
Seatbelts are typically provided with ROPS equipped tractors.
Infotainment Features:
Basic instrumentation (tachometer, temperature gauge, oil pressure light, fuel gauge). No advanced infotainment systems typical of modern tractors.
Driver Assistance Features:
Mechanical PTO engagement, potentially hydraulic power steering. Focus is on mechanical reliability and operator control, not electronic aids.
Connectivity Options:
None (No electronic connectivity or data logging features).
Engine Oil Change:
Typically every 250-500 operating hours, depending on operating conditions and oil type used. Refer to manual for exact interval.
Fuel Filter Replacement:
As recommended, often tied to oil change intervals or when issues arise, typically every 250-500 hours.
Hydraulic Fluid Change:
Generally every 1000-1200 operating hours. This is critical for the longevity of the hydraulic system.
Engine Oil Type:
API CD or CE rated diesel engine oil, viscosity grade SAE 15W-40 or 20W-50 is common. Consult manual for exact specification and ambient temperature range.
Hydraulic Fluid Type:
Tractor Hydraulic Fluid (THF) or a compatible universal tractor transmission oil (UTTO). Specific Case IH specification may apply. Capacity typically 35-50 Liters.
Transmission Oil Type:
GL-4 rated gear oil for the gearbox. Powershift units may require specific THF or UTTO. Refer to manual for precise specification.
Common Wear Points:
Wear on clutch plates, PTO engagement collar, hydraulic pump and valve spools, and steering cylinder seals are common in older units.
Electrical Gremlins:
Older wiring harnesses can degrade, leading to intermittent electrical issues. Faulty starter solenoids and alternator issues are also possible.
Engine ப்புகள்:
While generally robust, turbocharger issues, injector pump wear, and head gasket failures can occur with high mileage and poor maintenance.
David Brown Legacy:
David Brown was a highly respected British tractor manufacturer known for its robust and reliable engineering, particularly in the agricultural sector.
1690 Development:
The 1690 was part of Case IH's (post-acquisition of David Brown by Tenneco, which also owned Case) tractor lineup, representing a powerful and versatile machine in the late 1970s and 1980s. It evolved from earlier David Brown models.
Production Period:
Mid-to-late 1970s through the 1980s.
Manufacturing Location:
Primarily manufactured in the United Kingdom (e.g., Meltham, Yorkshire).
