Additional Notes

  • The John Deere W series models covered by these specifications span the 2010-2019 model years and are equipped with Tier 4/Stage IV emissions-compliant engines, all of which incorporate a selective catalytic reduction (SCR) system requiring AdBlue (DEF).
  • The W540, W550, W650, and W660 each carry an identical AdBlue tank capacity of 33 liters, indicating a uniform reservoir size across all four models in the range despite differences in model designation.
  • A 33-liter AdBlue capacity is a relatively substantial tank volume for agricultural machinery, reflecting the sustained field operation cycles typical of combine harvesters, where frequent refilling interruptions would reduce productivity.
  • All four configurations list normal use conditions, meaning the 33-liter capacity figure applies to standard operating environments rather than severe-duty or first-fill scenarios.
