Krone Big M

AdBlue (DEF) capacity & service interval

The Krone Big M uses AdBlue (DEF) fluid with a capacity of 70 liters. The data covers normal use service intervals. There are 3 configurations included in the data.

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

Additional Notes

  • The Krone Big M AdBlue (DEF) tank capacity is 70 liters across all three listed configurations, covering both the CR and CV variants as well as the serial number range 942021 onward.
  • A 70-liter AdBlue reservoir is a notably large capacity, consistent with heavy-duty agricultural machinery where extended field operation between refills is a practical requirement.
  • All three configurations specify normal use conditions, meaning the 70-liter capacity figure applies to standard operating circumstances rather than severe or first-change-only scenarios.
  • The Big M450 CV spanning serial numbers 942021 to 1029939 covers the 2018-2020 production period and carries the same 70-liter AdBlue capacity as the Stage V variants introduced from serial number 1029939 onward.
  • Both the Big M450 CR Stage V and the Big M450 CV Stage V share the 70-liter AdBlue capacity from serial number 1029939 onward, indicating that the transition to Stage V emissions compliance did not alter the tank size between the CR and CV driveline configurations.
  • All listed configurations describe the AdBlue system as a selective catalytic reduction (SCR) system, which is the emissions aftertreatment technology that consumes the DEF fluid to reduce nitrogen oxide emissions in diesel engines.
