McCormick X4 V

AdBlue (DEF) capacity & service interval

The McCormick X4 V uses AdBlue (DEF) fluid with a capacity of 7.5 liters. The data covers 5 configurations of this model.

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

The McCormick X4 V AdBlue tank capacity is 7.5 liters across all five variants — the X4.080 V, X4.090 V, X4.100 V, X4.110 V, and X4.120 V — each paired with the Deutz TCD2.9 L4 engine from 2023 onward.
A 7.5-liter AdBlue tank is a relatively modest reservoir, typical of compact utility tractors where packaging space is limited and refill frequency is managed through operational use patterns rather than large tank volume.
All five configurations share an identical 7.5-liter capacity, meaning no variant in the X4 V lineup carries a larger or smaller AdBlue reservoir despite differences in rated power output across the model range.
Each row is designated for normal use conditions, which in AdBlue system contexts refers to standard operating loads and ambient temperatures rather than extended or severe-duty cycles.
The AdBlue system in all listed variants is identified as a selective catalytic reduction system, or SCR. SCR technology injects AdBlue into the exhaust stream to convert nitrogen oxides into nitrogen and water, enabling compliance with emissions standards.
The Deutz TCD2.9 L4 is a four-cylinder engine platform shared across the entire X4 V range, and the uniform 7.5-liter AdBlue capacity reflects a single tank design applied consistently to all power variants built on that engine family starting in 2023.
