What model year did Kubota tractors start using the Diesel Exhaust Fluid???

I'm in the market for a good used Kubota tractor for general homestead use and I'd like to find an older one with low hours back before this stuff was required.

I think everything past 2008* with more than 75 horsepower was required to use DEF.

*Or close to that year

Unless you’re looking at a larger utility sized tractor 70+hp, no models require DEF of any year.

OK, thanks. I'm looking at tractors with 40hp to 50hp.... so, hopefully I can get one that does not need the DEF bs put in to it...

The 2 I'm considering are listed below... think these are decent prices, or should I try top talk them down a little?


2007 Kubota L4400 4WD
$19,960.00

44hp 4x4 621 hours


2009 KUBOTA Tractors M4800
$19,900

50hp 4x2 720 hours

Anyone before 2012 will not have any exhaust non-sense on it.

I like my 6.7 Ford diesel, it doesn't smoke, stink or rattle and has a lot of horsepower. I would not want an old 7.3 that was about as uncivilized as they come. Adding some DEF a couple of times a year is a small price to pay to get something that isn't a pig. While I don't have a tractor that is large enough to have a DEF system, I would have no problem with running a modern engine.

Adding DEF is a minor inconvenience, the real Tier IV emissions pain is the fuel wasting, extreme exhaust temperature creating, problem prone DPF (diesel particulate filter).

Hmm. That's not what the Messick's video says:

once we go up above 26 horsepower between 26 and about 75 that's the point where you're able to treat most of your exhaust without death so you're meeting those emission standards at either a DPF a diesel particulate filter or a DOC a diesel oxidation catalyst every tractor has one of the two in that 26 275 horsepower range
That starts at the 4:39 mark.

Kubota's do not use DEF, They use DPF


jyoutz, is almost right, he was off by 5hp.

0-25HP = No emissions
26-75 = DOC or DPF
75+ = DEF

But he said none had DEF. The way I understood Messick's, some might have DEF. Some might have DOC.

So he's right (minus the 5hp) for Kubotas, because they don't use DEF? Is that a correct understanding?

What he said:

What he should have said:

This is true, because Kubota does not use DEF on any tractor under 75HP.

Neil said DPF not DEF for under 75HP

I think your confusing DEF with DPF.

DEF = Diesel Exhaust Fluid
DPF = Diesel Particulate Filter
DOC = Diesel Oxygen Catalyst

They are 3 different animals in the emissions battle.

So the tractors over 75hp dont also have a DPF along with the def fluid like trucks?

Also what assurances are out there that a gov entity wont require destroying or retrofitting non emisions tractors? Could be only a few short years away never know.

Well, I've learned that I can get one that does not need DEF and is not a pig.

I don't need extra un-necessary crap on my new-to-me tractor.

All this emissions business is a bunch of BULLoney regardless of what type of vehicle they're wanting to regulate.

In fact, here is some information from 1200 of the world's top scientists who say there is NO climate emergency at all!....



The World Climate Declaration (Link to their PDF doc listing all the folks that signed this)

The declaration was organized by Climate Intelligence, an independent
policy foundation founded in 2019 by Dutch emeritus professor of geophysics
Guus Berkhout and Dutch science journalist Marcel Crok.
