Fendt Farmer 100

Differential fluid capacity & service interval

Fendt Farmer 100 differential fluid capacity ranges from 4,5 to 5 liters. Service intervals include checks at 100 and 250 hours, and changes at 1000 hours or 12 to 24 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 front differential fluid capacity across the Fendt Farmer 100 series splits into two values: 4.5 liters for the 102 S/SA, 103 S/SA, 104 S/SA, and 105 S/SA variants, and 5 liters for the 106 S/SA and 108 S/SA variants. The higher capacity in the larger models reflects a physically larger differential housing.
  • The 1000-hour change interval is consistent across all Fendt Farmer 100 series variants listed, regardless of model year or capacity. The time-based component of the change interval, however, differs between production periods.
  • Farmer 102 S/SA and 103 S/SA units produced between 1977-1985 carry a 12-month maximum service life for front differential fluid alongside the 1000-hour interval. Units of the same models produced from 1985-1992 extend the time-based limit to 24 months, meaning fluid can remain in service twice as long by calendar before a change is required.
  • The check interval for the Farmer 102 S/SA and 103 S/SA also changed between production periods. The 1977-1985 specification calls for a fluid level check every 100 hours, while the 1985-1992 specification extends the check interval to 250 hours. A 250-hour check interval is 2.5 times less frequent than the earlier 100-hour requirement.
  • The 104 S/SA, 105 S/SA, 106 S/SA, and 108 S/SA variants all share the 100-hour check interval and the 1000-hour/12-month change interval, matching the earlier-period specification used on the 102 and 103 variants before the 1985 revision.
  • All specifications listed apply under normal use conditions. No severe-use intervals are listed for any variant in the Farmer 100 series front differential system.
  • The 104 S/SA, 105 S/SA, 106 S/SA, and 108 S/SA are each listed only for the 1977-1982 period, while the 102 S/SA and 103 S/SA span a longer range through 1992, with a documented specification revision at the 1985 mark.
