Additional Notes

  • The Massey Ferguson MF 9S series uses a selective catalytic reduction system to manage exhaust emissions. SCR technology works by injecting AdBlue, a urea-based diesel exhaust fluid, into the exhaust stream to convert nitrogen oxides into nitrogen and water vapor.
  • All six MF 9S variants introduced in 2023 share an identical AdBlue tank capacity of 70 liters. A uniform tank size across the full model range means the same reservoir design is used regardless of engine output level.
  • A 70-liter AdBlue capacity is notably large by agricultural equipment standards, reflecting the extended field operation cycles typical of high-horsepower tractors where frequent refilling would interrupt work.
  • The capacity figure of 70 liters represents the total tank volume under normal use conditions. Normal use in fluid specifications generally refers to standard operating environments without the accelerated consumption or shortened intervals associated with severe duty cycles.
  • The MF 9S range covered by these specifications spans six variants: the 9S.285, 9S.310, 9S.340, 9S.370, 9S.400, and 9S.425. The numerical suffixes correspond to approximate engine horsepower ratings, indicating a wide spread of power outputs all sharing the same AdBlue system capacity.
