Additional Notes

  • The John Deere 8RT series AdBlue (DEF) tank capacity is 31.3 liters across all four configurations covered by serial number range 923001 onward from 2019.
  • A 31.3-liter DEF tank is a substantial reservoir by agricultural equipment standards, reflecting the extended field operation cycles typical of large row-crop tractors where frequent refilling would interrupt productivity.
  • All four variants, the 8RT 310, 8RT 340, 8RT 370, and 8RT 410, share an identical 31.3-liter capacity, meaning the DEF tank volume does not scale with the power rating differences between models.
  • Each configuration is noted as using a selective catalytic reduction (SCR) system, which is the emissions control technology that consumes DEF by injecting it into the exhaust stream to convert nitrogen oxides into nitrogen and water.
  • The capacity figure of 31.3 liters applies under normal use conditions for all listed variants, and no separate severe-use or first-fill capacity is specified for any of the four models.
