Additional Notes
- The McCormick X5 Series AdBlue system is associated with selective catalytic reduction (SCR), a technology that injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide emissions.
- SCR systems require a dedicated fluid reservoir separate from the fuel tank, and the 19-liter capacity listed across the X5.40, X5.50, and X5.60 represents the total volume of AdBlue the tank holds when filled.
- A 19-liter AdBlue tank is a moderately sized reservoir for agricultural equipment, reflecting the fluid consumption demands of Tier 4i / Stage IIIB emissions-compliant engines operating in field conditions.
- The X5.40, X5.50, and X5.60 variants all share an identical 19-liter AdBlue capacity, meaning no variation in tank size exists across the three engine output levels within the T4i / Stage IIIB configuration starting from 2019.
- All three variants carry a Normal use condition designation for the 19-liter AdBlue capacity, indicating the specification applies to standard operating conditions rather than a severe-duty or first-fill scenario.
