Additional Notes

  • The Fendt 300 Vario COM3b front differential holds 7 liters of fluid across all five variants covered by the 2012-2014 specifications, spanning the 309, 310, 311, 312, and 313 Vario models.
  • A 7-liter front differential capacity is a moderately sized fill for an agricultural tractor axle, consistent with the demands placed on front-wheel-assist differentials in this horsepower class.
  • The check interval for the front differential is set at 500 hours under normal use conditions, meaning fluid level and condition are to be inspected at that point before the full change interval is reached.
  • The change interval is specified at 1000 hours or 12 months, whichever comes first under normal use conditions, combining an operational hour threshold with a calendar-based limit to account for varying levels of annual machine activity.
  • The 500-hour check interval falls exactly at the midpoint of the 1000-hour change interval, structuring a two-stage maintenance cycle for the front differential fluid.
  • All five model variants — identified by serial number series 322, 323, 324, 325, and 340 — share identical front differential fluid capacity and service interval specifications for the 2012-2014 production period, with serial numbers beginning at 1001 in each case.
