Common engines would be turbocharged, inline 6-cylinder diesel engines). Displacement: Likely variants of 8.3L Cummins engines for higher horsepower models (e.g., 6CTA8.3), but other engine options might exist. Manual will specify exact displacement for each model. Performance Typical Horsepower Range: 8670 (approx. 140-160 HP), 8770 (approx. 160-180 HP), 8870 (approx. 180-200 HP), 8970 (approx. 200-220 HP). Exact figures depend on engine variant and PTO horsepower rating. Typical Torque Range: Highly dependent on specific engine displacement (e.g., 8.3L Cummins). Fuel System Type: High-pressure common rail (HPCR) or mechanical injection systems, depending on engine model. The manual would detail specifics of fuel pumps, injectors, filters, and high-pressure lines. 🔧 Transmission Standard Type: New Holland IntelliShift™ or PowerShift™ transmissions (e.g., 18-speed or 19-speed forward/reverse options). Gear Count: Often 18 forward and 6 reverse...
