Additional Notes

  • The Fendt L series AdBlue system is identified in the specifications as a selective catalytic reduction (SCR) system, which is an emissions control technology that injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide emissions.
  • All four configurations covered — the 5255 L, 5255 L PL, 6275 L, and 6275 L PL — share an identical AdBlue tank capacity of 80 liters, indicating no variation across the lineup in this regard.
  • An 80-liter AdBlue capacity is notably large relative to many agricultural and commercial vehicle applications, reflecting the extended operational demands typical of high-horsepower tractors used in field work.
  • The 80-liter figure represents the tank capacity rather than a service fill volume, meaning the full quantity would only be relevant when the tank is completely empty, while routine top-ups would involve smaller amounts.
  • All capacity values are listed under normal use conditions, meaning the 80-liter specification applies to standard operating environments rather than severe-duty cycles.
  • The PL variants of both the 5255 L and 6275 L share the same 80-liter AdBlue capacity as their standard counterparts, indicating the PL designation does not alter the SCR system's tank size.
  • Coverage for all four configurations begins from 2014, with no differentiation in AdBlue capacity between the lower-powered 5255 L models and the higher-powered 6275 L models.
