Displacement approx. 2.5 Liters (152 cu in). Known for fuel efficiency and reliability in lighter applications. Perkins A 4 236: 4-cylinder, naturally aspirated diesel. Displacement approx. 3.9 Liters (236 cu in). A workhorse engine providing more power and torque for heavier tasks. Perkins P4000: Likely a 4-cylinder variant, possibly related to the A4.236, offering robust performance. Perkins 1000 Series: A range of 4 and 6-cylinder engines, typically higher horsepower and torque, designed for more demanding applications, including turbocharged variants. Performance Horsepower Range: Varies significantly by model and engine, generally ranging from approximately 45 HP to 85 HP. Torque Characteristics: Designed for strong low-end torque crucial for pulling heavy loads and operating at lower engine speeds. Fuel System Fuel Type: Diesel Injection System: Typically direct injection systems, possibly with rotary or inline injection pumps (e.g., CAV, Simms, Lucas). 🔧 Transmission Gearbox Types 8X2 Sliding Gears: A non-synchronized gearbox offering 8 forward and 2 reverse gears. Requires double-clutching for shifting between gears. Known for ruggedness but can be less user-friendly. 8X2 Synchromesh: Similar gear count to the sliding gears but features synchromesh engagement for easier, smoother shifting without double-clutching. Enhances operator comfort and reduces transmission wear. 12X4 Constant Mesh: Features 12 forward and 4 reverse gears. Constant mesh means gears are always in mesh, but dog clutches or collars engage them. May or may not have synchromesh on all gears. Offers a wider range of speeds. 12X4 Partial Synchromesh: Offers 12 forward and 4 reverse gears with synchromesh on some, or all, gear engagement points for improved shifting. Provides a balance of speed selection and ease of use. Clutch Primary Clutch: Likely a single or dual-stage dry clutch, actuated by the clutch pedal. Dual-stage clutches may be used to engage the PTO separately. Features Pto Engagement: Independent PTO (IPTO) or transmission-driven PTO (T-PTO) depending on the specific model and configuration. The manual covers both. 📐 Dimensions Exterior Overall Length: Variable by model, typically in the range of 3.5 to 4.2 meters (138 to 165 inches). Overall Width: Variable by model and tire size, generally around 1.8 to 2.2 meters (71 to 87 inches) at the rear axle. Wheelbase: Variable by model and drivetrain, typically 2.1 to 2.4 meters (83 to 94 inches). Weights Operating Weight: Approximately 2,000 kg to 3,000 kg (4,400 lbs to 6,600 lbs), depending on configuration (2WD/4WD, loader attachments, etc.). 🛡️ Safety Features Ratings Rollover Protection: While ROPS (Roll-Over Protective Structure) may have been an option or standard on later models, earlier configurations might...
