John Deere 5R(N) series

Additional Notes

• The John Deere 5R(N) series tractors covered in these specifications span the 5090R, 5100R, 5115R, and 5125R models across the 2017-2022 production years, all equipped with a selective catalytic reduction (SCR) system that uses AdBlue (DEF) to reduce nitrogen oxide emissions from diesel exhaust.
• SCR systems require a dedicated fluid reservoir separate from the engine and hydraulic systems, and the capacity figures listed here represent the total fill volume of that AdBlue tank rather than a consumption rate or service interval quantity.
• The 5090R, 5100R, and 5115R share an identical AdBlue tank capacity of 11.4 liters under normal use conditions, indicating a common reservoir design across three power variants within the series.
• The 5125R carries a slightly reduced AdBlue tank capacity of 11.2 liters under normal use conditions, a difference of 0.2 liters compared to the three lower-output models in the same series.
• All four models are specified under normal use conditions, meaning the 11.4-liter and 11.2-liter capacity figures apply to standard operating environments rather than severe-duty or high-load duty cycles.
• The marginal capacity difference between the 5125R and the 5090R-5115R group is notable given that higher-output engines typically consume AdBlue at a greater rate relative to diesel fuel, making tank volume a relevant factor in refill frequency during field operation.
