Deutz-Fahr C 9300

AdBlue (DEF) capacity & service interval

The Deutz-Fahr C 9300 uses AdBlue (DEF) fluid with a capacity of 85 liters. Four configurations of this model are covered.

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

Additional Notes

  • The Deutz-Fahr C 9300 AdBlue system is associated with selective catalytic reduction (SCR), a technology that injects a urea-based fluid into the exhaust stream to reduce nitrogen oxide emissions in compliance with Stage IV emissions standards.
  • All four configurations covered — the C9305 TS, C9305 TSB, C9306 TS, and C9306 TSB — share an identical AdBlue tank capacity of 85 liters, indicating no variation in SCR reservoir size across the TS and TSB variants or between the 05 and 06 engine designations.
  • An 85-liter AdBlue capacity is notably large relative to many agricultural machines, reflecting the extended operational cycles typical of combine harvesters, where frequent refilling interruptions would reduce field efficiency.
  • The capacity figure of 85 liters represents a service fill value, meaning the amount the tank holds during normal operation rather than a dry-fill or overhaul measurement tied to system replacement.
  • All listed configurations carry a Stage IV emissions classification, which is the European off-road machinery standard requiring SCR integration as part of the exhaust aftertreatment architecture.
  • The specifications apply under normal use conditions across all four variants, meaning the 85-liter capacity figure is not adjusted for severe-duty or alternative operating scenarios within the data provided.
