Additional Notes

  • The John Deere S7 series AdBlue (DEF) system holds a capacity of 74.2 liters across the S600, S700, S800, and S900 variants, all from serial number 835001 onward starting in 2023.
  • A 74.2-liter DEF tank is a notably large reservoir, consistent with the demands of heavy-duty agricultural machinery where extended field operation between refills is a practical necessity.
  • All four variants — S600, S700, S800, and S900 — share an identical 74.2-liter DEF capacity, meaning no variation in tank size exists across the lineup within serial number range 835001 onward.
  • The DEF system in each variant is identified as a selective catalytic reduction (SCR) system, which is the emissions control technology that consumes AdBlue to convert nitrogen oxides into nitrogen and water through a chemical reaction with exhaust gases.
  • The capacity figure of 74.2 liters applies under normal use conditions, as specified for all four S7 variants in the 835001-onward serial range beginning in 2023.
