Fendt 900 Vario MT Gen2, T-T9B

AdBlue (DEF) capacity & service interval

Fendt 900 Vario MT Gen2 and T-T9B models utilize AdBlue (DEF) with a capacity of 71 liters. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

  • Use: Normal
  • Capacity 71 liter

Additional Notes

  • All three configurations listed for the Fendt 900 Vario MT Gen2 share an identical AdBlue tank capacity of 71 liters, which represents the total fluid volume the selective catalytic reduction system reservoir holds.
  • The 71-liter capacity is notably large relative to typical on-highway diesel equipment, reflecting the extended field operation cycles expected of agricultural tracked machinery where frequent refill stops are impractical.
  • The 938 Vario MT (T-T9BA), 940 Vario MT (T-T9BC), and 940 Vario MT (T-T9BE) each carry the same 71-liter specification under normal use conditions, meaning no variation in AdBlue tank size exists across the two power ratings represented in these rows.
  • The selective catalytic reduction system noted across all three rows is an emissions control technology that injects AdBlue into the exhaust stream to convert nitrogen oxides into nitrogen and water, making the tank capacity directly relevant to how long the machine can operate before an AdBlue refill is required.
  • All specifications listed apply to normal use conditions, which in fluid service contexts generally refers to standard operating environments as opposed to severe or extended-duty cycles that might alter consumption rates or service intervals.
