Valtra (Valmet) A4 series

Differential fluid capacity & service interval

Valtra (Valmet) A4 series differential fluid capacity ranges from 4,4 to 6 liters. Service intervals include checks every 12 months or 500 hours and changes every 1000 hours. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Valtra (Valmet) A4 series front differential fluid capacity splits into two distinct groups across the 2018-2020 model range. The A74, A84, and A94 share a 4.4-liter capacity, while the A104 and A114 each require 6 liters.
  • The 6-liter front differential capacity on the A104 and A114 is notably larger than the 4.4-liter figure seen on the lower models, reflecting the greater physical size of the front axle differential housing on higher-output variants.
  • All five models in the 2018-2020 A4 series carry identical front differential check intervals under normal use conditions: every 12 months or 500 hours, whichever comes first. The dual-trigger format means calendar time and operational hours are treated as equally valid thresholds.
  • The front differential fluid change interval is set at 1,000 hours across all A4 series models from 2018-2020, applying uniformly under normal use conditions regardless of whether the tractor carries the 4.4-liter or 6-liter capacity specification.
  • The check interval of 500 hours falls at exactly half the 1,000-hour change interval, meaning a fluid condition inspection occurs at the midpoint between each scheduled change across all listed A4 series configurations.
  • The A74, A84, and A94 share not only the same 4.4-liter front differential capacity but also identical check and change intervals, indicating no differentiation in service scheduling among those three models for the 2018-2020 period.
