Additional Notes

  • The Farmtrac FT 535 carries a rear differential fluid capacity of 29 liters, a volume consistent with a combined rear axle and transmission housing common in agricultural tractors of similar size, where the differential shares a common sump with other drivetrain components.
  • The FT 555 and FT 555DT share the same 29-liter rear differential capacity as the FT 535, while the DT variant adds a front differential with a separate 4-liter capacity, reflecting the additional front axle drive hardware on four-wheel-drive configurations.
  • Front differential capacities across the F series increase with model size. The FT 555/555DT front differential holds 4 liters, the FT 670/670DT and FT 675/675DT each hold 4.5 liters, and the FT 685DT, FT 690DT, FT 7100DT, and FT 7110DT each hold 5.5 liters, indicating progressively larger front axle assemblies in the higher-numbered models.
  • All front differential service intervals across the F series are set at 600 hours under normal use conditions, regardless of the variation in fluid capacity between models.
  • Rear differential service intervals are specified at 1000 hours or 12 months, whichever comes first, under normal use conditions. The dual-trigger format means time elapsed can mandate a fluid change even when the hour threshold has not been reached, which is relevant for tractors used in lower-intensity seasonal operations.
  • The front differential change interval of 600 hours is shorter than the 1000-hour rear differential interval, a difference that reflects the greater mechanical stress and contamination exposure typical of front axle differentials in four-wheel-drive tractors operating over uneven terrain.
  • The 5.5-liter front differential capacity shared by the FT 685DT, FT 690DT, FT 7100DT, and FT 7110DT represents the largest front axle fluid volume in the F series specifications listed, suggesting a common front axle assembly across the upper tier of the lineup.
