Engine Manufacturer:
Cummins (typically for this series, though New Holland also uses FPT/IVECO engines in some configurations - confirmation specific to model year is advised).
Engine Displacement:
Likely 8.3L or 9.0L (ISB/ISL series for Cummins, or NEF series for FPT/IVECO) - exact displacement varies by specific model within the T8 series.
Horsepower Range:
Approximately 270 HP (T8.270) up to 390 HP (T8.390), with potential for power boost on higher-end models.
Torque Delivery:
High torque ratings suitable for heavy draft work, with torque curves optimized for low-end pull and sustained power.
Fuel Injection Type:
Common Rail Diesel Injection (CRDI) with electronic control.
Emission Standards:
Designed to meet Tier 4A/Tier 4B/Stage III B/Stage IV (depending on manufacturing year and region), likely utilizing SCR (Selective Catalytic Reduction) and DPF (Diesel Particulate Filter) technologies.

Cab Features:
Often equipped with advanced cab features including integrated armrest controls, color displays for monitoring tractor functions and implement settings, and potentially Bluetooth/radio systems.
Guidance Systems:
Compatibility with GPS guidance systems (e.g., New Holland's IntelliSteer™ or Trimble/John Deere autosteer systems) for precision agriculture, row-crop guidance, and auto-turn functionality.
Telematics:
May include telematics systems (e.g., New Holland's PLM Connect) for remote monitoring, diagnostics, fleet management, and data logging.
Electronic Management:
Advanced electronic control units (ECUs) manage engine, transmission, hydraulics, and implement control for optimal performance, efficiency, and operator comfort.
Engine Oil Change:
Typically every 500 hours or annually, but refer to the manual for specific engine and oil type. Includes oil and filter replacement.
Hydraulic Oil Change:
Typically every 1000-2000 hours or every 2 years, with filter changes more frequent. Specific interval depends on operating conditions and oil type.
Transmission Oil Change:
Varies by transmission type (Powershift vs. CVT), but generally in the range of 1000-2000 hours. Filter replacement is also critical.
Engine Oil:
API CJ-4 or newer (e.g., CK-4), SAE 15W-40 or 10W-30 (depending on climate), meeting manufacturer specifications (e.g., ACEA E7/E9, Cummins CES 20081).
Hydraulic Fluid:
New Holland Hydraulic Fluid (NH 134) or equivalent premium UTF (Universal Tractor Transmission Fluid) or ISO VG 46 Hydraulic Oil, depending on system requirements.
Transmission Fluid:
Specific Powershift or CVT fluid as recommended by New Holland/CNH Industrial. May be a dedicated transmission oil or a specialized UTF.
Common Wear Items:
Hydraulic pumps and valves due to high operating pressures, wear in powershift transmission clutches, electronic control unit (ECU) glitches, HVAC system components, and DPF regeneration issues (especially if operated in short-cycle or light-load applications).
