Additional Notes

  • The Claas Lexion 8000 series automatic transmission fluid capacity is 17.9 liters across all listed configurations, covering the Lexion 8700, 8800, and 8900 variants in both standard and TerraTrac undercarriage versions.
  • The 17.9-liter figure applies specifically to the transmission with differential lock, meaning a transmission without a differential lock may carry a different volume, though no such configuration appears in the listed specifications.
  • All five configurations share an identical service interval of 500 hours or 12 months under normal use conditions, whichever comes first in operation.
  • The dual-trigger interval structure, combining an hourly threshold with a calendar limit, reflects standard practice for heavy agricultural machinery where seasonal or low-hour operation could otherwise delay fluid renewal beyond a safe period.
  • Tier 3/Stage IIIA emissions-rated variants of the Lexion 8700 and 8800 carry the same 17.9-liter transmission capacity and 500-hour/12-month interval as their non-Tier 3 counterparts, indicating no difference in transmission specification between emission standard variants within the same model.
  • The CS86 designation appears across all listed rows, identifying a common threshing and separation system configuration shared by the 8700, 8800, and 8900 in the specifications, with no variation in transmission fluid capacity tied to that designation.
