Additional Notes

  • The Fendt 900 Vario MT AdBlue system is tied to a selective catalytic reduction (SCR) setup, which is an emissions control technology that injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide output.
  • A 71-liter AdBlue tank capacity is notably large compared to many agricultural machines, reflecting the extended field operation cycles typical of high-horsepower tracked tractors where frequent refilling would cause significant downtime.
  • The 938 Vario MT (T-T9AA), 940 Vario MT (T-T9AC), and 943 Vario MT (T-T9AE) all share an identical 71-liter AdBlue capacity, meaning no variation exists across these three model variants despite their differing engine outputs.
  • All three variants carry a normal use condition designation for the 71-liter capacity figure, indicating the specification applies to standard operating conditions rather than a severe-duty or first-fill scenario.
