Additional Notes

  • The Krone Big M II transfer box capacity of 6 liters applies uniformly across all configurations covered by the 2004-2011 specifications, including the CM, CRi, CV, and base variants. In agricultural machinery, a transfer box at this fill level typically indicates a unit handling significant torque distribution demands across driven axles or driveline components.
  • The 10-hour check interval is notably short by general machinery standards and reflects the high-stress operating environment of a self-propelled forage harvester. At this frequency, the check is intended to catch fluid loss or contamination early rather than to replace fluid, keeping the transfer box within safe operating parameters between full service events.
  • The fluid change interval is set at 500 hours or 12 months, whichever comes first. The dual-trigger structure means that machines with lower annual usage still require a change on a calendar basis, preventing fluid degradation from oxidation and moisture absorption over time regardless of operational hours accumulated.
  • All eight configurations across the CM, CRi, CV, and base serial number ranges share identical transfer box specifications. The consistency across variants with different serial number brackets, such as the CRi spanning 550.000-577.949, 577.950-601.999, and 602.000 onward, suggests the transfer box assembly remained unchanged across those production runs.
  • The serial number segmentation within the CRi and CV variants, dividing production at 577.950 and again at 602.000, is a common manufacturer practice for tracking component revisions or supplier changes. Despite these production breakpoints, the transfer box fluid capacity and service intervals remain at 6 liters, 10-hour checks, and 500-hour or 12-month changes throughout.
  • All specifications are designated for normal use conditions. In agricultural equipment service documentation, normal use typically refers to standard field operating conditions as opposed to extended high-load or extreme-environment scenarios, meaning the 500-hour and 12-month intervals reflect expected duty cycles under typical harvesting operations.
