Additional Notes

  • The Hesston (Fiatagri) 7700's transfer case carries a fluid capacity of 3 liters, which represents a service fill volume typical of a working transferbox rather than a full overhaul drain-and-refill figure.
  • The 7730 configuration specifies a change interval of 1,200 hours or 12 months, whichever comes first, under normal use conditions, meaning standard agricultural operating loads without the accelerated wear factors associated with severe-duty cycles.
  • The dual-trigger interval structure, combining an hour-based threshold with a calendar-based threshold, reflects the reality that a machine accumulating low annual hours could still experience fluid degradation over time independent of mechanical wear.
  • The 3-liter capacity figure applies specifically to the 7730 variant within the 1986-1993 production span, and no variation in transfer case fluid volume is indicated across that range for the noted configuration.
