I know that the Massey 1835M that i have on order is stage V compliant. Im not crazy about the reliability of emissions equipment but the tractor had everything else i wanted.
I have not had the opportunity to research Stage V vs Tier IV Final. I know i have read that it has been implemented in Europe. My gut tells me its another level of Tier IV since it is not written as TIER V.
I look forward to anyones response that has more insight into the matter.
