Performance Power Output: Varies by model, generally ranging from approximately 45 HP (466) to 80 HP (80-66). Torque Output: Varies by model, providing ample torque for agricultural applications. Fuel System Fuel Type: Diesel Injection System: Typically direct injection, often with Bosch or similar rotary/inline injection pumps. Cooling System Cooling Type: Water-cooled, typically with a thermostat-controlled circulating system and a radiator. Lubrication System Oil Type: Diesel engine oil, viscosity and specification dependent on ambient temperature and manufacturer recommendations (e.g., API CD/CE or equivalent). Engine Family Engine Design: Robust, heavy-duty diesel engines designed for continuous operation under demanding agricultural conditions. 🔧 Transmission Standard Transmission Type: Manual transmission (e.g., 8-speed, 12-speed, or 16-speed synchromesh, often with a dual-speed PTO). Optional Optional Features: +DT (Dual Traction) models indicate front-wheel drive capability. Features Gear Selection: Likely features a main gearbox lever and a range selector, possibly a creeper gear. Clutch: Single dry plate clutch for transmission, often a independent PTO clutch. Pto System: Likely features a 540 RPM PTO, possibly with an optional 1000 RPM PTO, engaged via a dedicated lever or clutch mechanism. 📐 Dimensions Exterior Wheelbase: Varies by model, indicative of standard 2WD and optional 4WD configurations. Weights Operating Weight: Approx. 2000-3500 kg (1000-7700 lbs), depending on specific model and configuration (e.g., 2WD vs. 4WD).
