Iseki TF

Differential fluid capacity & service interval

Iseki TF differential fluid capacity ranges from 4,1 to 4,5 liters. Service intervals consist of a 100 hour check and a 300 hour change. The data covers 8 configurations.

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

Additional Notes

  • Across all eight Iseki TF configurations listed, the front differential fluid change interval is set at 300 hours under normal use conditions, with a check interval at the 100-hour mark.
  • The 100-hour check interval is a level verification rather than a full drain-and-fill, allowing early detection of fluid loss or contamination between the scheduled 300-hour changes.
  • The TF 317 and TF 321 models, in both hydrostatic and mechanical transmission variants, share a front differential fluid capacity of 4.1 liters.
  • The TF 325 and TF 330 models carry a slightly larger front differential capacity of 4.5 liters, regardless of whether the transmission is hydrostatic or mechanical.
  • The 0.4-liter difference in front differential capacity between the smaller-displacement models (TF 317, TF 321) and the larger ones (TF 325, TF 330) reflects a physically larger differential housing in the higher-output variants.
  • Within each model designation, the hydrostatic (FH) and mechanical (FM) transmission variants carry identical front differential fluid capacities and service intervals, indicating the differential assembly itself is shared between the two drivetrain configurations.
  • Hour-based service intervals, as used here, are standard practice for agricultural and compact utility tractors, where annual mileage is not a reliable measure of mechanical wear due to variable load and terrain conditions.
  • All eight configurations share a starting year of 1998, meaning the 300-hour change and 100-hour check intervals apply uniformly across the entire TF series as specified from that point forward.
