Additional Notes

  • All six variants of the Fendt 900 Vario COM3b covered here — the 924, 927, 930, 933, 936, and 939 Vario — share an identical brake fluid capacity of 0.5 liter, indicating a uniformly small reservoir volume consistent with a supplementary hydraulic circuit rather than a primary braking medium.
  • Each variant is noted as having a pneumatic brake system, which means compressed air serves as the primary braking force. The 0.5-liter brake fluid capacity in such a configuration typically relates to a hydraulic actuation or modulation component within the broader pneumatic circuit, not a conventional fully hydraulic brake system.
  • The Stage IIIb / EPA 4i emissions designation applies across all six variants, placing them within a specific regulatory tier for off-road diesel engines that was in effect during the 2011-2013 model years covered by these specifications.
  • The capacity figure of 0.5 liter is a service fill value, representing the fluid volume relevant during routine maintenance of the brake fluid reservoir. A value this small is characteristic of a partial-circuit or actuator-level fill rather than a full system overhaul volume.
  • All six rows carry a normal use condition, meaning the 0.5-liter capacity applies under standard operating circumstances without adjustment for severe-duty or special-application scenarios.
  • The serial number structure shown for each variant — such as 941/../0101 for the 924 Vario — indicates a production sequence starting point, with the capacity specification applying from that serial number onward within the 2011-2013 range.
