Why the worry ? The Nebraska tests exist for a reason .

I was just at the Mahindra dealer pricing tractors. I do not know if Mahindra has to pass anything to come into the U.S. It seems like other countries get a different set of rules than we do. I would hate to purchase a 75 pto hp tractor to later find out my 40k tractor is only 65. Right now I am going to drive a Case 75c. I know it is not 75 on the pto. I have to decide if less will do what I need but by the same time I need to know I am comparing apples to apples. My Mahindra dealer tells me that every Mahindra goes on the dyno before he receives it to verify the power.

I am sure Tier IV is mandatory at 25-horsepower, not 26-horsepower. All the "cheater" engines are 24.2, 24.6, 24.8 horsepower. Kubota uses DPF (diesel particulate filters.) technology on Tier IV compact tractor engines, with excepton of B2650. No blue DEF.

Most feel less stringent emission standards for <25 horsepower tractors are permanent. Personally, I feel this dispensation is temporary, probably disappearing when cleaner Tier V standards arrive.

RE B50s: Kubota's paper catalog states: "Diesel Particulate Filter (DPF) is compliant with the latest Tier 4 Final emission regulations (B3350)." B2650 is compliant too but apparently without needing a DPF. This may or may not be due to B2650's smaller 77 cubic inch engine, viz 91.5 cubic inch engine in B3350.

I am not involved with Kubota, other than as a consumer. I try to keep current on what Kubota is doing and how Kubota is doing it but it is difficult as Kubota constantly introduces minor changes, mostly improvements. Kubota catalogs and brochures often are a bit behind what is on dealer lots.

Tier IV Questions For Messicks NEW THREAD 8/2/2018

1) Is the demarcation for Tier IV emissions controls 25-horsepower or 26-horsepower?

2) kubota B2601 specs as 68.5 cubic inch displacement / 25.5 horsepower. Does B2601 have Tier IV emission controls, specifically DPF?

3) Kubota B2650 has 77 cubic inch displacement / 26 horsepower. Does B2650 have Tier IV emission controls, specifically DPF?


Thank you for illumination.

Interesting, L2501 has over 100ci engine 26hp, and no DPF.

26 seems to be the magic number, anything more and DPF or another add on emission system goes in place. Probably why there are a lot of 25 & 26hp tractors and few if any 27-29 hp now.

I am looking at Kubota L2501 brochure before me. Kubota L2501 has 24.8 horsepower/18.5 kW engine rating.

The actual Tier IV demarcation is 19 kW which translates to 25.4794 horsepower.

OK I stand corrected about the L2501. And apparently Kubota "rounds" what must their actual 25.4 hp B2650 up to an even 26 in their marketing.

I've sure drifted this thread, back to the OP's topic.

Screamin, you satisfied that none of us know of any brand cheating going on in this market? I've never read of any, though I'm sure some manufacturer might have gotten embarrassed at official trials when they came up a little short. Usually hp equates directly to number of discs or feet of planter or whatever on ag tractors, so if you buy enough tractor, and it doesn't work well, sure might make you wonder. I watch a lot of youtube farming videos and seems to me most farmers aren't maxxing out the tractor. I don't see a lot of videos where big grain carts are overturned along with the tractor. See tons of them getting stuck in mud though. So having a reserve of traction vs hp is often a more usable choice. Why tracked tractors are so popular, plus they ride a lot better apparently. Like buying a house. or two... I think the rubber hits the road when someone buys a big batwing mower for the first time. That's an implement many of us non farmers might buy that requires serious hp. Though if you buy a five foot rear tiller and your 25hp SCUT just dies on you, same problems.

now to likely offend someone...even though my last name is German, almost a dozen of my relatives went into the ovens in WWII. The ones who hadn't immigrated like my grandfather did.
That was sure the Big Lie. Then I owned a VW TDI and had the worst dealership experience ever. The people, not the car, were dishonest.
While the sales manager was off getting some paper done, he didn't turn off his pc, which was running a sales training tape on how to basically BS
the customer, deflect hard questions about recalls, talk about bland topics. My jaw dropped listening to it, how to schmooze your customers, baffle them with BS
and here's the corporate training on how to do that. The Big Lie was in full effect. So how do you trust a dealership like that?
So to answer the OP's question, I bet if anyone would try to lie in this business it would be the Germans, and they deserve this pie in the face.
Good thing big ag John Deere competes against them and I bet JD keeps them honest.

I just received my new Q5 Audi built in Germany, btw, so I believe you have to move on.
But I don't trust them at all, even though different tunes are being sung.
Just like at Wells Fargo.
Good thing most German tractors aren't imported here so it's not an issue at all. Lot of big factories there that used to build IH and JD models I believe.

let's see, who is left to insult? ;) Lot of tractors made in India, my 2615 was, so are lots of JD 5 series, or were.
I wouldn't worry about the Indians. Those Perkins clones are likely pretty well sorted out by now.

ok, based on all my personal life experiences, though, if I project personal honesty characteristics onto a tractor manufacturer,
I think I'd most worry about a tractor built in Russia. I have lived among many Russians. Most were dishonest in some fashion, some acted
like suburban gypsies, how can I not report any income, how can I screw my insurance company with a phony roof repair.
So I wouldn't trust them at all to not hype power ratings. But their tractors tend to be unbreakable which seems to be a lot more relevant to their owners.

nothing like useless but fun anecdotal evidence. Sorry if anyone offended. This might disappear quickly.

The service manager that dynoed my tractor, told me he NEVER dynoed even one Deutz that didn't have a fair amount more pto power than it was rated, and over the years he had dynoed a pile of them!

Do you know where Deutz are made??
