Additional Notes

  • The Case IH Axial-Flow 50 Series specifies a 162-liter AdBlue (DEF) tank capacity across the 7240, 8240, and 9240 models, all introduced in 2021.
  • A 162-liter DEF reservoir is notably large by agricultural equipment standards, reflecting the extended field operation cycles typical of high-capacity combine harvesters, where frequent refilling would interrupt productivity.
  • All three models — the 7240, 8240, and 9240 — share an identical 162-liter capacity figure, meaning no variation exists in DEF tank size across the lineup despite differences in model designation.
  • Each row is associated with a selective catalytic reduction (SCR) system, which is the emissions control technology that consumes DEF to reduce nitrogen oxide (NOx) emissions from diesel exhaust.
  • The use condition listed for all three configurations is normal, meaning the 162-liter capacity figure applies to standard operating conditions rather than severe-duty or first-fill scenarios.
