Approx. 45-75 PTO HP depending on the specific model (e.g., 885/995 likely in the lower range, 1210/1212 in the higher range).
Fuel System Type:
Direct injection diesel, typically utilizing a distributor-type fuel injection pump (e.g., Simms, CAV) and inline fuel filters.
Transmission Type:
Manual gearbox with multiple forward and reverse gears. Common configurations included 8-speed or 12-speed transmissions, often with a high/low range selector.
Optional Transmission Features:
Some models may have offered a live Power Take-Off (PTO) or a synchronised PTO, and some higher-horsepower models might have featured an independent PTO clutch.
Pto Options:
Standard PTO (540 RPM) is common, with potential for live PTO or independent PTO depending on the specific model and configuration.
Safety Features Included:
The manual will cover safety aspects of tractor operation, maintenance, and repair. This includes safety warnings for specific procedures, proper use of ROPS (Roll-Over Protective Structures) if fitted, and safe handling of fluids and components. Specific safety ratings or crash test data as known in modern automotive contexts are not directly applicable to tractors of this era; focus is on operational safety.
Engine Oil Change Interval:
Typically 250-500 operating hours, depending on operating conditions and oil type used. The manual will specify exact intervals and oil specifications.
Transmission Fluid Change Interval:
Typically 1000-1200 operating hours. The manual will detail the specific interval and fluid type.
Engine Oil Specification:
API CD or equivalent, SAE 15W-30 or 10W-30, with specific capacity around 7-9 liters (depending on engine). The manual will provide precise API rating and viscosity recommendations.
Hydraulic Fluid Type:
Typically a universal tractor transmission oil (UTTO) or a specific hydraulic oil compatible with David Brown systems. Manual will specify CAT 303 or equivalent and viscosity. Capacity around 20-30 liters.
Common Wear Items:
Common wear items can include clutch friction plates, hydraulic pump seals, PTO clutch packs, and front axle kingpins. The manual's troubleshooting section is invaluable for diagnosing and addressing these.
Model Evolution:
The JI Case David Brown lineup, including these models, evolved from the original David Brown tractors acquired by Case. These models represent a solid iteration of British tractor design integrated into the Case product line, aiming for reliability and efficiency in agricultural applications. They were produced through the 1970s and into the early 1980s.
