New Holland FX

Power steering fluid capacity & service interval

New Holland FX uses power steering fluid with a capacity of 10 liters. Service intervals occur every 600 hours or 12 months. The data covers 4 configurations.

Additional Notes

  • The New Holland FX series forage harvesters, covering the FX28, FX38, FX48, and FX58 from 1999-2004, all share an identical power steering fluid capacity of 10 liters for the steering system rear axle.
  • A 10-liter capacity in a power steering circuit is notably large compared to typical automotive applications, which reflects the scale and hydraulic demands of full-size self-propelled forage harvesting equipment.
  • The steering system rear axle designation indicates the fluid serves the rear axle steering circuit specifically, rather than a centralized hydraulic reservoir shared across multiple machine functions.
  • The change interval for all four FX variants is set at 600 hours or 12 months under normal use conditions, meaning whichever threshold is reached first would govern the service timing in practice.
  • A 600-hour interval on a forage harvester is calibrated around seasonal and annual operation patterns, where 12 months serves as a time-based backstop for machines that may not accumulate high hours within a single year.
  • The uniformity of both the 10-liter capacity and the 600-hour/12-month interval across the FX28, FX38, FX48, and FX58 suggests the rear axle steering system architecture remained consistent across the model range during the 1999-2004 period.
