Cadillac of tractors?

why no turbo.. NA engines have a hard time breathing sometimes..

From what I see, a turbo ups the initial cost about $1000, requires longer shutdown procedures, and potentially higher repair bills. It's an EPA thing, not a performance issue. Kubota only picks up ONE horsepower with their turbo models. The non turbos perform just fine.

Now maybe it makes a useful performance improvement in the really big tractors (e.g. over 150 HP), I don't know. But my preference would be non turbo.

Those are really non issues.

Oh? How do you see that as "non issues"?

This is a common misnomer. It used to be true, but it isn't anymore. Especially with compact tractors.

So... Unless we're talking about a 4020 (real tractor not compact model) or a 55 or 60 series John Deere Tractor, you are indeed mis-informed.

In compacts, Kubota, hold their resale value the best. It's not even that close.

"Real" tractor? I hope you're not implying compacts aren't 'real' tractors.

As for resale, I'd like to see the proof of this.

"Misnomer"? A misnomer is a wrong label. Calling a frog a flog, for example. If your statement is true it's a 'misconception'. And I'm speaking of Deere in general, that's all their equipment.

I look at engines overall. The greatest longevity is most often the lowest power per liter. Two engines of equal hp but different volumes, the larger volume will usually last the longest.

I like normally aspired engines on my cars and tractors, I'll go with the lower hp larger block (3320 as opposed to the 3520, for example). My friend had a turbo Porsche, what a pain, even after Porsche got the turbo lag problem under control. We used to sit in his garage waiting for it to cool down so we could shut it off.

You can make a really beefy engine and turbo it but you still have the complexity of the turbo, the heat and the higher cost. You have this tiny bearing spinning its b*lls off at 100k rpm as it's being battered by exhaust gasses. That can't be good even if you use ceramic bearings.

Sorry for the thread drift.

Because of potential higher repair costs or reliability issues (ie something else to break). And for what?, being that Kubota can make the same power without a turbo.

I don't know what you mean about non-turbo'd engines having a hard time breathing. I've had about 18 cars/ trucks in my life, two boats, lawn mowers, weedeaters, chainsaws, etc, not a single turbo, & none have had any kind of hard time breathing that I could tell.

Probaby what is meant, is a turbo engine usually adds about 10 hp and at the same time uses less fue and more effecientl. That is why you are seeing more and more of that in the new Auto/Truck industry products. Ken Sweet

I agree, a hard time breathing is a design quality issue not a turbo/non turbo issue.

Ken,
I'm not sure, it may be hp to size -You get more hp for less metal. Also does a turbo get better mileage? You're just pushing more air which means more fuel to keep the ratio constant. Better economy would mean higher efficiency, I'm not sure turbos provide that. Am I wrong?

Yes, My experience is definitly less fuel usage on tractors with turbos. I had a 393 MF tractor that was turbo and gained 10 hp over the 383 non turbo and got great fuel economy. I love my Dodge 1 ton truck with the Cummins Turbo engine--I pull loads often at 17 MPG (highway) Ken Sweet
