Case - IH Magnum AFS Connect

Additional Notes

• The Case - IH Magnum AFS Connect AdBlue (DEF) system operates through a selective catalytic reduction (SCR) setup across all listed Tier 4b variants starting from 2019.
• All specifications are recorded under normal use conditions, meaning the capacities listed reflect standard operating fill levels rather than values tied to severe-duty or first-change scenarios.
• The Magnum 180, 200, 220, and 240 AFS Connect Tier 4b models share an identical DEF tank capacity of 88.2 liters, indicating a common SCR tank configuration across the lower-output range of the lineup.
• Beginning with the Magnum 250 AFS Connect Tier 4b, the DEF tank capacity increases to 99 liters, representing a step up of approximately 10.8 liters compared to the lower-output models.
• The 99-liter DEF capacity is consistent across the Magnum 250, 280, 310, 340, 380, and 400 AFS Connect Tier 4b variants, covering the full upper portion of the model range.
• A DEF tank capacity of 88.2 liters is a substantial reservoir by agricultural equipment standards, reflecting the extended field operation cycles typical of large-frame tractors where frequent refilling would be impractical.
• The capacity split between the two groups — 88.2 liters and 99 liters — aligns with the distinction between the sub-250 and 250-and-above power ratings, suggesting the larger engine configurations consume DEF at a rate that warrants the additional tank volume.
