Recommended printing on durable paper for workshop use. ⚙️ Engine Specifications Primary Engine Primary Engine: The series utilizes robust David Brown diesel engines. Examples include the AD4/44 (3.4L, 4-cylinder) for models like the 1190/1194 and AD6/47 (5.4L, 6-cylinder) for models like the 1690. Specific engine codes and configurations are detailed within the manual for each tractor model. Performance Performance: Engine power ratings range from approximately 55 HP for the 1190 up to 100+ HP for the 1690. The manual provides precise horsepower, torque curves, and RPM specifications for optimal engine operation. Fuel System Fuel System: Features typically include Simms or CAV fuel injection pumps and injectors. The manual details the overhaul, calibration, and timing procedures for these critical fuel delivery components, as well as fuel filter service and bleeding procedures. 🔧 Transmission Standard Standard: Standard transmission is a fully synchronized gearbox, often with 12 forward speeds and 4 reverse speeds, offering versatile gearing for different field conditions. Some earlier models might have had 8-speed transmissions. Optional Optional: Optional extras could include a creeper gearbox for ultra-low speeds or specialized PTO options. The manual will detail any variations. Features Features: The manual covers clutch operation (single or dual-stage for independent PTO), transmission fluid type and change intervals, differential lock engagement, and the operation of the independent PTO system (often 540/1000 RPM selectable). 📐 Dimensions Exterior Exterior: Wheelbase, overall length, width, and height are model-specific. For example, the 1190 might have a wheelbase of around 80-85 inches, while larger models would be longer. Precise figures are in the 'Specifications' section. Weights Weights: Unladen weights vary significantly, from approximately 5,500 lbs for smaller models to over 7,500 lbs for the 1690. Maximum permissible weights for safe operation and transport are also detailed. 🛡️ Safety Features Ratings Ratings: Safety guidelines focus on operational best practices, correct component assembly, torque specifications for critical fasteners (e.g., wheel nuts, axle components), and safe fluid handling, rather than formal crash ratings. Active Features Active Features: Key active safety features include reliable braking systems (disc or drum, often with hydraulic actuation), positive differential lock, and the responsive steering system, all of which are thoroughly explained in the manual. Passive Features Passive Features: The design of the operator's station, including the seat and control layout, is covered. While ROPS (Roll-Over Protective Structures) were often optional or dealer-fitted, the manual may reference structural integrity requirements. 💡 Technology Features Infotainment Infotainment: N/A. The focus is on functional mechanical and hydraulic systems. Driver Assistance Driver Assistance: Power steering (on most models) and the differential lock are primary...
