Farmtrac F series

Automatic transmission fluid capacity & service interval

Farmtrac F series uses automatic transmission fluid with a capacity range of 12 to 46 liters. Service intervals occur every 1000 hours or 12 months. The data covers 8 configurations.

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

Additional Notes

  • The Farmtrac F series automatic transmission fluid intervals are expressed as a dual condition: 1000 operating hours or 12 months, whichever comes first. In agricultural equipment, operating hours are the primary measure of mechanical wear, while the calendar interval accounts for fluid degradation during periods of low use.
  • All eight configurations in the F series share the same 1000-hour/12-month change interval under normal use conditions, regardless of transmission type or fluid capacity.
  • The FT 535 and FT 555/555DT are specified with semi-automatic transmissions, a designation that distinguishes them from the transaxle configurations found across the larger models in the lineup. A semi-automatic transmission automates gear engagement while retaining a manual gear selection mechanism.
  • Both the FT 535 and FT 555/555DT carry a 12-liter fluid capacity. In the context of semi-automatic agricultural transmissions, a 12-liter fill is consistent with a moderately sized gearbox rather than a combined drivetrain housing.
  • The FT 670, FT 670DT, FT 675, and FT 675DT are each specified with a 38-liter transaxle capacity. A transaxle integrates the transmission, differential, and axle into a single housing, which accounts for the substantially larger fluid volume compared to the semi-automatic units in the smaller models.
  • The FT 685DT and FT 690DT carry the largest transaxle capacity in the F series at 46 liters, representing a notable step up from the 38-liter figure of the FT 670 and FT 675 variants. The difference of 8 liters reflects a larger combined drivetrain housing in these higher-output models.
  • The FT 7100DT and FT 7110DT are specified with a 35-liter transaxle capacity. Despite carrying model numbers that suggest a higher position in the range, their fluid capacity falls between the 38-liter and 46-liter transaxle figures of other F series configurations, indicating a different transaxle design rather than a direct size progression by model number.
  • Across the transaxle-equipped models, three distinct capacity values appear: 35, 38, and 46 liters. These differences reflect variations in transaxle size and internal volume rather than differences in service interval requirements, as all transaxle models share the same 1000-hour/12-month change schedule.
