Additional Notes

  • The Landini Series 6C carries a 24-liter AdBlue (DEF) tank capacity across all six configurations spanning the 2014-2021 model range. A 24-liter reservoir is a mid-to-large capacity for agricultural tractors, reflecting the extended field operation cycles typical of this equipment class.
  • All six configurations share an identical 24-liter SCR tank capacity regardless of engine output rating. The 6-120C, 6-130C, and 6-140C variants cover the T4i / Tier IIIB emissions standard applied to the 2014-2017 production years, while the 6-125C, 6-135C, and 6-145C variants correspond to the Tier 4 Final standard introduced from 2017 onward.
  • T4i (Tier 4 Interim) and Tier IIIB are equivalent emissions classifications used in North American and European regulatory frameworks respectively. Both standards require SCR technology to reduce nitrogen oxide (NOx) emissions, which explains the presence of a dedicated AdBlue tank in the 2014-2017 Series 6C models.
  • Tier 4 Final, applied to the 6-125C, 6-135C, and 6-145C from 2017-2021, represents a stricter NOx reduction threshold than Tier 4 Interim. Despite the tighter emissions requirement, the SCR tank capacity remains at 24 liters across both emissions tiers, indicating the same physical reservoir design was carried over between generations.
  • The model year boundary of 2017 marks the transition point between the T4i / IIIB and Tier 4 Final variants within the Series 6C lineup. The 6-120C, 6-130C, and 6-140C designations were replaced by the numerically adjacent 6-125C, 6-135C, and 6-145C designations at that boundary, with the slight output figure changes reflecting the revised engine calibrations associated with the updated emissions standard.
  • All capacity figures listed are for normal use conditions. In SCR system contexts, a single capacity value under normal use typically represents the full usable tank volume rather than a service-fill or reserve figure, meaning the 24 liters reflects the total fluid the reservoir holds during standard operation.
