Additional Notes

  • The Case - IH Maxxum CVT AdBlue (DEF) system operates as a selective catalytic reduction (SCR) setup, which injects diesel exhaust fluid into the exhaust stream to reduce nitrogen oxide emissions.
  • The Maxxum 110 CVT, Maxxum 120 CVT, and Maxxum 130 CVT share an identical AdBlue tank capacity of 37 liters across their 2015-2020 production span.
  • The Maxxum 115 CVT, Maxxum 125 CVT, Maxxum 135 CVT, and Maxxum 145 CVT each carry a larger AdBlue tank capacity of 39.5 liters, representing a 2.5-liter increase over the 37-liter group.
  • All capacity figures listed are normal-use values, meaning they reflect standard operating fill levels rather than overhaul or dry-fill quantities.
  • The 37-liter capacity group is associated exclusively with model variants introduced in 2015, while the 39.5-liter capacity group corresponds to variants with a starting year of 2016.
  • A 39.5-liter AdBlue reservoir is a relatively large tank for agricultural tractor applications, which reduces the frequency of fluid top-ups during extended field operations.
