Landini 4 series

AdBlue (DEF) capacity & service interval

Landini 4 series vehicles utilize AdBlue (DEF) with a capacity range of 75 to 80 liters. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

The Landini 4 series AdBlue tank capacity is specified as a range of 75-80 liters across the 4-070D, 4-080D, and 4-090D configurations, which is consistent with the large reservoir demands of agricultural equipment operating over extended field hours between refills.
All three engine variants covered by the specifications — the Deutz C4DT50 and C4DT55 — share the identical 75-80 liter capacity range, indicating a common tank architecture across the 4-070D, 4-080D, and 4-090D models for the 2018-2021 period.
The 75-80 liter figure represents a service fill capacity rather than a dry or overhaul fill, meaning the actual total system volume may differ slightly depending on residual fluid levels at the time of replenishment.
Each row in the specifications carries a Selective Catalyst Reduction (SCR) notation, identifying AdBlue consumption as part of an emissions control process in which urea solution is injected into exhaust gases to reduce nitrogen oxide output in compliance with Tier 4 Final (T4f) standards.
The capacity range notation of 75-80 liters rather than a fixed single value reflects a fill tolerance, which is common in large-tank SCR systems where precise fill level detection may vary slightly by sensor calibration or fill method.
All specifications are listed under normal use conditions, meaning the 75-80 liter capacity figure applies to standard operating environments rather than severe-duty or high-load duty cycles.
