Additional Notes

  • The New Holland FX series covers four model variants — the FX28, FX38, FX48, and FX58 — all spanning the 1999-2004 model years, and all share identical manual transaxle fluid specifications across the lineup.
  • Each variant carries a manual transaxle fluid capacity of 15 liters, which is a substantial fill volume consistent with the large-scale drivetrain demands of self-propelled forage harvesters in this class.
  • A 15-liter capacity in a manual transaxle context typically reflects a service fill figure, meaning the amount required during a standard drain-and-refill service rather than a complete overhaul where additional passages and cavities may hold residual fluid.
  • The fluid change interval for all four variants under normal use conditions is set at 600 hours or 12 months, whichever comes first, applying a dual-trigger structure that accounts for both operational intensity and calendar-based fluid degradation.
  • The 600-hour threshold is notable for heavy agricultural equipment, as forage harvesters typically accumulate hours in concentrated seasonal bursts, meaning the 12-month calendar limit may often govern the service schedule in lower-utilization operations.
  • The uniform 15-liter capacity and 600-hour/12-month interval across the FX28, FX38, FX48, and FX58 indicates no variation in manual transaxle service requirements despite the differing power and throughput ratings that distinguish the individual models within the range.
