Common engines include the Oliver/Perkins diesel series. Performance Typical Horsepower: Varies significantly by model: 66 series typically 30-40 HP, 77 series 40-50 HP, 88 series 50-60+ HP. 770 and 880 models generally represent upgraded versions with potentially higher power outputs. Fuel System Carburetion Injection: Gasoline models utilize carburetor systems. Diesel models feature robust diesel injection pump systems (e.g., CAV, Simms, or Bosch depending on engine source). Cooling System Cooling Type: Water-cooled, typically with a thermostat-controlled system and fan. Lubrication System Oil Pump Type: Gear-driven oil pump, integrated within the engine block. 🔧 Transmission Standard Gearbox Type: Constant mesh, sliding gear transmissions. Common configurations include 4, 5, or 6 forward gears and one or two reverse gears. Some models feature a creeper gear option. Optional Transmission Options: Some models may have offered dual-range transmissions or live PTO (Power Take-Off) options. Features Clutch Type: Single dry-plate clutch for primary transmission engagement. Dual-clutch systems for independent PTO engagement were available on some models. Hydraulic System: Integrated hydraulic system for implement control (e.g., 3-point hitch, external hydraulics). Features may include position control, draft control, and live hydraulics. 📐 Dimensions Exterior Wheelbase: Varies by model, typically around 80-90 inches for the standard wheel tractor configurations. Weights Operating Weight: Generally in the range of 4,000 - 6,000 lbs (1800 - 2700 kg) depending on configuration and implement hitch. Drawbar Horsepower: Often specified as a key performance metric, typically correlating to engine horsepower but adjusted for drivetrain efficiency. 🛡️ Safety Features Ratings Operator Protection: Original models predate modern ROPS (Roll-Over Protective Structure) and seatbelt mandates. Manual would detail safe operating practices and potential modifications.
