Additional Notes

  • The Massey Ferguson MF Activa AdBlue system operates through a selective catalytic reduction (SCR) setup, which is a diesel exhaust aftertreatment technology that injects a urea-based fluid into the exhaust stream to reduce nitrogen oxide emissions.
  • All four configurations covered — the MF 7340 and MF 7344 across both their 2016-2020 and 2021-onward production periods — share an identical AdBlue tank capacity of 80 liters under normal use conditions.
  • An 80-liter AdBlue reservoir is a notably large tank capacity, consistent with the demands of heavy-duty agricultural machinery that operates for extended hours between refill opportunities.
  • The MF 7340 carries the same 80-liter AdBlue capacity across both the 2016-2020 and the 2021-onward variants, indicating no change in tank sizing between those production periods.
  • The MF 7344 likewise maintains the 80-liter AdBlue capacity across both the 2016-2020 and 2021-onward variants, mirroring the consistency seen in the MF 7340 specifications.
  • All capacity figures are stated under normal use conditions, meaning the 80-liter value reflects standard operating demands rather than a modified or severe-duty scenario.
