Massey Ferguson MF 5S

Additional Notes

• The Massey Ferguson MF 5S AdBlue tank holds 20 liters across all ten configurations in the lineup, spanning the 105, 115, 125, 135, and 145 power variants in both Dyna-4 and Dyna-6 transmission forms introduced from 2021.
• A 20-liter AdBlue capacity is a mid-range figure for agricultural tractors in this power class, large enough to reduce refill frequency during extended field operations without adding excessive weight to the front of the machine.
• All ten configurations carry the selective catalytic reduction (SCR) designation, meaning AdBlue is injected into the exhaust stream upstream of a catalyst, where it converts nitrogen oxides into nitrogen and water vapor to meet emissions standards.
• The uniform 20-liter capacity across both the Dyna-4 and Dyna-6 transmission variants indicates the AdBlue tank design is shared regardless of the number of transmission ratios, with the Dyna-4 offering four powershift steps and the Dyna-6 offering six.
• The capacity figure of 20 liters represents a service fill value, reflecting the usable volume of the tank during normal operation rather than a dry-fill or overhaul measurement that would account for system lines and pump priming volumes.
• All specifications are listed under normal use conditions, which in agricultural equipment typically refers to standard duty cycles rather than extended high-load or dusty environments that might accelerate fluid consumption rates.
• The five power variants in the MF 5S range, from the 105 to the 145, share an identical AdBlue tank capacity, suggesting a common chassis architecture governs tank placement and volume rather than engine output level.
