What year did "emissions" tractors and equipment start?

[Wobblin-Goblin]

Was it 2008?

I'm looking at a John Deere backhoes for sale (310s and 410s) and am curious when the last of the non-emissions tractors and equipment were. I think it was '07, but I'm not sure.

Thanks.

Stricter Tier IV off-road diesel engine emission reduction standards phased in dealer tractor inventory during 2009 - 2012, impacting tractor prices.

It started earlier than that for cars. I remember my 71 Grand Prix having all manner of pollution junk on it--Vacuum lines everywhere controling valves and doors. The Quadra jet on top of a 400 was the only thing keeping it ahead of the VW bugs.

Actually, T3 came about around 2002 for tractors. I own a 2002 T3 interem Kubota. Still mechanical fuel injection but with a wastgated turbo to cut down on visible particulates (smoke). When it became T3 final is when the stupidity started.

Here is alink to a document with the full scope and time frame of the EPA's meddling on diesels;
Emission Standards: USA: Nonroad Diesel Engines

Tier 4 emission standards—Engines up to 560 kW, g/kWh (g/bhp-hr)

Engine Power	Year	CO	NMHC	NMHC+NOx	NOx	PM
kW < 8 (hp < 11)	2008	8.0 (6.0)	-	7.5 (5.6)	-	0.4a (0.3)
8 ≤ kW < 19 (11 ≤ hp < 25)	2008	6.6 (4.9)	-	7.5 (5.6)	-	0.4 (0.3)
19 ≤ kW < 37 (25 ≤ hp < 50)	2008	5.5 (4.1)	-	7.5 (5.6)	-	0.3 (0.22)
2013	5.5 (4.1)	-	4.7 (3.5)	-	0.03 (0.022)
37 ≤ kW < 56 (50 ≤ hp < 75)	2008	5.0 (3.7)	-	4.7 (3.5)	-	0.3b (0.22)
2013	5.0 (3.7)	-	4.7 (3.5)	-	0.03 (0.022)
56 ≤ kW < 130 (75 ≤ hp < 175)	2012-2014c	5.0 (3.7)	0.19 (0.14)	-	0.40 (0.30)	0.02 (0.015)
130 ≤ kW ≤ 560 (175 ≤ hp ≤ 750)	2011-2014d	3.5 (2.6)	0.19 (0.14)	-	0.40 (0.30)	0.02 (0.015)
a - hand-startable, air-cooled, DI engines may be certified to Tier 2 standards through 2009 and to an optional PM standard of 0.6 g/kWh starting in 2010 b - 0.4 g/kWh (Tier 2) if manufacturer complies with the 0.03 g/kWh standard from 2012 c - PM/CO: full compliance from 2012; NOx/HC: Option 1 (if banked Tier 2 credits used)—50% engines must comply in 2012-2013; Option 2 (if no Tier 2 credits claimed)—25% engines must comply in 2012-2014, with full compliance from 2014.12.31 d - PM/CO: full compliance from 2011; NOx/HC: 50% engines must comply in 2011-2013

If I'm reading that chart correctly, a 90hp John Deere 310 or 410 loader backhoe didn't have much for emissions equipment until 2013. Is that correct?

Teir 3 hit them around 2008 which was fuel timing and injector styles also many had gotten EGR between 2004-2008. But no DPF/DOC or DEF till around 2013. There were some common rail electronic injected motors prior to tier 4 many of those had much better torque curves and fuel economy then the same engine with mechanical injection.
Case in point on the Farm the IH Puma 125 is a fancier much more electronic tractor then the similar NH 6050 which is a mechanical tractor just prior to tier 4. The PUMA starts better in cold weather and will pull hills faster and easier and gets better fuel economy when doing the same work.

My 2011 Kubota M7040 has older style inj pump & injectors but has an EGR valve

Ours is a 2007 310SG with the optional 410 bucket & cylinder. 4wd, extendahoe, weights, cab & AC. Also has a single rear remote - flow thru type for breaker rather than the preferred F/R valve for thumb.

It does not have any emissions equipment and has mechanical injection for each cylinder i.e. 4 separate pipes from fuel pump to injectors.

HOWEVER, it does have a computer and those early SG computers mounted in the engine compartmenta are known trouble spots. Later had the computer in the cab. Good for about 5000 hrs in the engine compartment. Symptom of failure beginning is swelling of case & temp gauge goes to full on starting.
The cost to repair is simple: About $3000 total. Another $2K to move the computer to the cab.

It works for us, but makes an argument for going to a pre-SG model at least.
