Diesel emissions

What year did the change in emissions for tractors with >25hp come about?

The DPF and all the flashing warning lights, buzzers and what not, that tell me how to run my tractor.

Thanks

I don't know about all manufacturers, but I believe Kubota started with Tier 4 standards beginning 2015.

Your question is not easily answered. See the LINK from the EPA website. You will have to convert HP to kW. Don't forget to read the notes. That will really make it clear....(NOT!):confused2:

I sure like the smokeless train engines and excavating equipment they build now.:thumbsup:

My goal is to find out, what were the last year model Deere's and Kubota's in the 30-40hp range,,,,
that breathed on their own,
prior to this DPF age.

I appreciate your input Mr Jeff, but I have no clue what the **** you just said.

I thought there would be a simple answer.

Like this here >>>>>>> in 2012 or 20?? all engines over 25hp require a bunch of EPA crap.

In other words
What year model Deere and Kubota 30-40 hp in the used market be available without the REGEN DPF compliance stuff. ??

I understand year model tractors are unlike vehicles but, there has to be a year model for each brand that did and did not comply to the current emissions

2014 was the last model year for JD prior to Tier IV implementation. I would imagine it would've been the same for Kubota.

I don't.

Before the DPF age tractor diesels still didn't exactly breath very well on their own. Starting about 2008, Kubota used EGR technology and parts to reburn the exhaust fumes in a lot of their tractors so that they could meet an loophole in the emission standard called "Tier IV Interm". Tier IV Interm reduced the nitrous oxides allowed in the exhaust but overlooked the resulting increased soot and particle production. Not good for motors, and made the diesel smoke even thicker. Some of those had terrible exhaust fumes, but technically they did meet the letter of the emission law.

So you have to go back at least 10 years to get to a place where engine efficiency was more important than emission control.
If that is your goal, look for something without EGR as well as without DPF. But you may not like the fumes very much.
luck,
