Additional Notes

  • The Fendt C series AdBlue system is classified under selective catalytic reduction (SCR), a technology that injects diesel exhaust fluid into the exhaust stream to convert nitrogen oxides into nitrogen and water vapor.
  • All five configurations across the 5275 C and 6335 C variants share an identical AdBlue tank capacity of 80 liters, indicating a standardized reservoir size across the C series lineup covered by these specifications.
  • An 80-liter AdBlue capacity is notably large relative to many agricultural machine applications, reflecting the extended field operation cycles typical of combine harvesters where frequent refilling would interrupt workflow.
  • The 5275 C and 5275 C PL-PLI both carry the same 80-liter capacity from their 2016 starting year, with no capacity differentiation between the standard and PL-PLI trim variants.
  • The 5275 C SL Stage V variant has a starting year of 2020, which is later than the 2016 starting year of the other 5275 C configurations, and still shares the same 80-liter AdBlue capacity despite the Stage V emissions classification.
  • Stage V refers to the European Union's fifth stage of non-road mobile machinery emissions regulations, which introduced stricter particulate number limits alongside the existing NOx standards already addressed by SCR systems.
  • All specifications are listed under normal use conditions, meaning the 80-liter capacity figure applies to standard operating environments rather than severe-duty or first-fill scenarios.
  • The 6335 C and 6335 C PL variants, both starting from 2016, carry the same 80-liter AdBlue capacity as the 5275 C range, showing no capacity variation between the two model designations within these specifications.
