Additional Notes

  • The Fendt 300 Vario S4 AdBlue system is classified under selective catalytic reduction (SCR), an exhaust aftertreatment technology that injects a urea-water solution into the exhaust stream to reduce nitrogen oxide emissions in compliance with Stage 4 emissions standards.
  • All ten variants across the 309-313 Vario range share a uniform AdBlue tank capacity of 23 liters, applying equally to both Power and Profi trim levels within each model number.
  • The 23-liter figure represents the total tank capacity rather than a service refill quantity, meaning actual consumption between refills varies depending on engine load, operating hours, and ambient conditions.
  • Capacity specifications are listed under normal use conditions across all rows, covering the full 2015-2021 model year span for each variant.
  • The Power and Profi designations represent distinct trim configurations within each model number, yet both share identical AdBlue tank capacities, indicating the SCR hardware is common across trim levels for a given model.
  • Each variant carries a unique serial number prefix distinguishing model and trim, with the 309 Power assigned prefix 346/23, the 309 Profi assigned 346/21, and subsequent model numbers incrementing the first segment accordingly through to the 313 series at prefix 350.
