Additional Notes

  • The Fendt 300 Vario Gen4 AdBlue system is identified in the specifications as a selective catalytic reduction (SCR) system, which is an emissions control technology that injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide emissions.
  • All four variants covered by the specifications — the 311, 312, 313, and 314 Vario — share an identical AdBlue tank capacity of 23 liters.
  • A 23-liter AdBlue capacity is a moderately sized reservoir for agricultural machinery, reflecting the sustained field operation cycles typical of tractors in this power class.
  • The capacity figure of 23 liters listed across all rows represents the total tank fill volume, which is the usable fluid capacity of the SCR reservoir rather than a partial or residual service quantity.
  • All specifications are assigned a normal use condition, meaning the 23-liter capacity value applies to standard operating circumstances rather than a severe-duty or first-fill scenario.
