Fendt GT series

Differential fluid capacity & service interval

Fendt GT series differential fluid capacity ranges from 3,45 to 7 liters. Service intervals include checking at 250 hours and changing at 1000 hours or 24 months. The data covers 8 configurations.

Additional Notes

  • The Fendt GT series Toolcarrier models span a production window of 1985-1991, with some variants such as the F 365 GT/GTA and F 380 GT/GTA covering the full range, while others like the F 370 GT/GTA, F 390 GTA, F 395 GHA, and F 395 GTA appear only from 1990-1991.
  • Front differential capacities vary considerably across the GT series lineup. The F 365 GT/GTA and F 380 GT/GTA share a 4.5-liter front differential capacity, the F 370 GT/GTA requires 6 liters, and the F 390 GTA, F 395 GHA, and F 395 GTA each call for 7 liters — reflecting the larger axle assemblies fitted to the higher-numbered models.
  • The F 370 GT/GTA is the only model in these specifications to list a rear differential, with two capacity values recorded: 3.45 liters and 3.8 liters. The presence of two figures for the same position typically indicates different axle configurations or variants within that model designation.
  • All differential positions across the GT series share an identical service interval structure: a fluid level check at every 250 hours of operation, and a full fluid change at 1,000 hours or 24 months, whichever comes first. The dual-trigger format of hours and calendar time reflects standard agricultural equipment practice, accounting for machines that accumulate hours slowly over multiple seasons.
  • A 250-hour check interval on a working tractor typically falls within a single season of moderate use, making it a routine in-season inspection point rather than a major service event. The 1,000-hour change threshold, by contrast, may span several years depending on annual usage.
  • The 24-month calendar limit on differential fluid changes exists because lubricants degrade through oxidation and moisture absorption over time, independent of operational hours. A machine with low annual usage could reach the time limit well before the 1,000-hour mark.
  • All specifications in the GT series differential data are designated for normal use conditions. No severe-duty intervals are listed for any model, meaning the 1,000-hour/24-month change schedule applies uniformly across standard operating environments for all variants shown.
