Additional Notes

  • The Valtra (Valmet) S4 series covers six model variants — S274, S294, S324, S354, S374, and S394 — spanning the 2019-2023 model years, all equipped with a selective catalytic reduction (SCR) system for exhaust aftertreatment.
  • SCR systems use a diesel exhaust fluid (AdBlue/DEF), a urea-water solution, injected into the exhaust stream to reduce nitrogen oxide (NOx) emissions in compliance with emissions regulations applicable to agricultural machinery.
  • All six S4 series variants share an identical AdBlue tank capacity of 60 liters, indicating a uniform tank design across the entire model range regardless of power output differences between variants.
  • A 60-liter AdBlue reservoir is a notably large capacity for agricultural equipment, reflecting the extended field operation cycles typical of high-horsepower tractors, where frequent refilling would otherwise interrupt work.
  • All capacity figures are specified under normal use conditions, meaning the 60-liter value represents standard operating fill rather than a maximum overhaul or system-flush volume.
