Horsepower Range:
Expected to range from approximately 95 to 115 engine horsepower, with corresponding PTO horsepower outputs slightly lower. Torque figures are substantial for this class of tractor, enabling efficient operation with demanding implements.
Torque Peak:
Torque figures are crucial for tractor performance, with peak torque often occurring in the 1300-1600 RPM range, providing strong pulling power. Specific Nm or lb-ft values will be detailed per model.
Fuel System:
Common Rail Direct Injection (CRDI) fuel system, often with turbocharging and intercooling for optimal performance and fuel efficiency. Emissions compliance would be to relevant Tier standards (e.g., Tier 4 Final/Stage IV).
Emissions Control:
Modern tractors utilize Diesel Oxidation Catalysts (DOC), Diesel Particulate Filters (DPF), and Selective Catalytic Reduction (SCR) systems to meet stringent emission standards. The manual will cover maintenance and regeneration procedures for these components.
Transmission Standard:
Often equipped with a Powershift transmission (e.g., 16x16, 20x20, or 24x24) offering multiple speed options for on-the-fly shifting without declutching. Some models may offer a SynchroShuttle or a 12x12 transmission.
Transmission Optional:
Depending on the specific configuration and market, optional transmissions could include creeper gears, a 4WD powershift, or different gear ratios for specialized applications.
