Additional Notes

  • The Landini Series 6C front differential fluid capacity depends on axle configuration rather than engine variant or model year. Rigid axle configurations, whether fitted with brakes or without, hold 7.6 liters, while the front axle with suspension holds 2.2 liters across all listed variants.
  • The 2.2-liter capacity associated with the front suspended axle configuration is notably lower than the 7.6-liter figure for rigid axle types. This difference reflects the smaller differential housing volume in a suspended front axle assembly compared to a full rigid axle unit.
  • The presence or absence of brakes on the rigid front axle produces no difference in differential fluid capacity. Both the braked and non-braked rigid axle configurations share the same 7.6-liter fill across all Series 6C variants listed.
  • All 18 rows across the Series 6C specification carry a uniform service interval of 1,000 hours or 12 months under normal use conditions, whichever comes first. The dual-trigger format means calendar time can mandate a fluid change even when the hour threshold has not been reached.
  • The T4i / IIIB emission-standard variants, covering the 6-120C, 6-130C, and 6-140C from 2014-2017, share identical front differential capacities and service intervals with the Tier 4 Final variants that followed. No capacity adjustment accompanied the transition to the stricter Tier 4f emission standard.
  • The Tier 4f variants, the 6-125C, 6-135C, and 6-145C from 2017-2021, represent the later emission-compliance generation of the Series 6C. Tier 4 Final refers to the U.S. EPA and equivalent EU Stage IV regulations requiring significantly reduced nitrogen oxide and particulate matter output from off-road diesel engines.
  • The 7.6-liter rigid axle differential capacity is a substantial volume for a front axle unit, consistent with heavy-duty agricultural tractor front axles that must accommodate both differential gearing and, in the braked variant, integrated wet brake assemblies within the same housing.
