Fendt 900 Vario S4

AdBlue (DEF) capacity & service interval

The Fendt 900 Vario S4 uses AdBlue (DEF) fluid with a capacity of 36 liters. Five configurations of this model are covered in the data.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Fendt 900 Vario S4 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 variants covered by the specifications — the 927, 930, 933, 936, and 939 Vario S4 — share an identical AdBlue tank capacity of 36 liters, indicating a uniform SCR tank design across the lineup for the 2018-2020 period.
  • A 36-liter AdBlue capacity is a substantial reservoir for an agricultural tractor, reflecting the extended field operation cycles typical of high-horsepower machinery where frequent refilling would be impractical.
  • Each variant carries a serial number threshold beginning at the 00F05001 suffix, which marks the specific production point from which the 36-liter capacity specification applies within the 2018-2020 range.
  • The use condition recorded across all five variants is normal, and under normal use the 36-liter capacity figure represents the standard service fill volume for the SCR tank.
