Additional Notes

  • The Valtra (Valmet) T4 Versu AdBlue system relies on selective catalytic reduction (SCR), a technology that injects a urea-water solution into the exhaust stream to convert nitrogen oxides into nitrogen and water vapor, reducing harmful emissions in line with modern agricultural machinery standards.
  • A 70-liter AdBlue tank capacity is specified across the T144 V, T154 V, T174 V, T194 V, T214 V, T234 V, and T254 V variants for the 2019-2021 model years, indicating a large-volume reservoir suited to extended field operation without frequent refilling stops.
  • The T254 V covering the 2017-2021 period carries a capacity range of 45-70 liters, distinguishing it from the fixed 70-liter figure assigned to all other listed variants and model year groupings.
  • The variable 45-70 liter range on the 2017-2021 T254 V suggests that tank size differed depending on build specification or configuration within that production span, whereas the 2019-2021 T254 V entry lists a fixed 70-liter capacity, reflecting a standardized tank for that narrower period.
  • All specifications across the T4 Versu AdBlue entries are designated for normal use conditions, meaning the stated 70-liter capacity figures apply to standard operating environments rather than severe-duty or high-load duty cycles.
  • The numerical designations within the T4 Versu lineup, ranging from T144 to T254, correspond to different power output classes, yet the AdBlue tank capacity remains uniform at 70 liters across the 2019-2021 entries, indicating a shared fluid reservoir design regardless of engine output tier.
