Additional Notes

  • The Valtra T4 Direct AdBlue (DEF) tank capacity is 70 liters across all six variants in the T144 D through T234 D range for 2019-2021, indicating a large-volume reservoir designed to extend refill intervals during heavy agricultural use.
  • A 70-liter AdBlue capacity is notably generous compared to many on-road commercial vehicles, which typically carry 20-40 liters. In agricultural machinery, larger tanks reduce the frequency of stops for refilling during long field operations.
  • All six variants, spanning the T144 D, T154 D, T174 D, T194 D, T214 D, and T234 D, share an identical 70-liter capacity despite representing a wide spread of power ratings across the T4 Direct lineup for 2019-2021.
  • Each row is designated for normal use conditions, meaning the 70-liter capacity figure applies to standard operating environments rather than severe-duty or extended-interval scenarios.
  • The selective catalytic reduction (SCR) system noted across all variants is the emissions control technology that consumes AdBlue. SCR systems inject DEF into the exhaust stream to convert nitrogen oxides into nitrogen and water, and tank size directly affects how long the tractor can operate before a refill is required.
  • Because the tank capacity is uniform across all six T4 Direct variants from 2019-2021, the 70-liter figure represents a platform-level design choice rather than a specification that varies with engine output or model designation.
