Cadillac of tractors?

[SPYDERLK]

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.

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

They hold their hp better at altitude.

1. Are there more parts to fail on a turbo than a normally aspired engine?

Has to be, parts you don't have can't fail! EVER

2. There is a whine:

"I do like the turbo whine, it is almost like music to my ears"

wolc123 just said it!

I don't like it!

3. What engine has greater stresses on it? One with a greater volume and less hp (Deere 3320) or one with less volume and more hp? (Deere 3720) All other factors being equal.

The one with more hp and less volume! Has to be.

John Deere specs fuel usage:

3320: 2 gph -full load, normally aspired, 33 hp
3520: 2.4 gph- full load, turbo, 37 hp

Period!

You want a turbo get one, I don't want one!

Turbos don't hold better at altitude. Wastegates are deisned to open, they lose hp just like normally aspired engines do.

If turbos don't fail than why are these guys rebiulding them?

Turbochargers.com | Turbo Sales service and professional turbocharger rebuilders

and these guys:

Turbo Repair and Turbocharger Repair - Turbo Repair Kits and Turbo Diesel Repair

This is also what they say:

"Maintain proper oil levels due to the tremendous heat created"


Must be me!

Nobody here agrees with you.

As I said earlier in this thread, I agree with Rob-D. To each his own, but I do not want to own a turbo, especially when I can get the same power from a non-turbo.

LOL!!! Then there are 2 of you out of 166 posts. I think that says enough in itself. About 1 or 2 percent of the people think the earth is flat. About the same percentage. Whatever. Just don't try to tell me that a turbo diesel is any less reliable than a regularly aspirated diesel. Sorry. Every engine has moving parts. Any part can break. If you want to remove half of the power that your engine was designed to produce, your choice.

33/37= 89%: how do you get "half of the power"?

Refute the data, your opinion is just that. If you don't have a part it can't go bad. There are places that fix turbos, what does that tell you? It tells me they can and do go bad.

Two engines are the same size, one develops more hp. Which engine has greater stress? Has to be the one developing greater hp, it's not up for debate, it's common sense, prove it wrong.

If popularity determined the truth Christians would be praying to Barabus and all those innocent people burned at the stake were really witches.
I gave you facts, you gave me your opinion.

I do like the turbo whine, it is almost like music to my ears, just a real soothing sound. Sometimes I will just park my tractor and pump the throttle a bit, just to hear that turbo spool up and down. However, what I like best about the turbo is the improved fuel economy that it enables. There was a time when fuel was cheap enough that having a turbo was really not such a big deal. I doubt we will ever see such a day again the way things are headed. So far, I have never seen or heard of a single problem with a turbo but I will admit that I was a little aprehensive before getting my first one. Since getting it however, I would surely never consider another diesel engine without one.

Other than the tiresome whine of working a turbocharged backhoe all day and the headache that accompanies it, I still prefer to have a turbocharged diesel, but I have had a few turbos take a dump at very inconvenient times. Luckily I could install them myself. Usually ends up a $750-$1,000 repair

My N/A Kubota has handled everything I can throw at it and begged for more and $10,000 less than a new turbo model with 1 more HP and a lot more pollution control crap that I could do without that decreases reliability.

Not being a rich boy, the choice was easy for me. Save $10,000 and suffer the "unbearable embarrassment" of owning a N/A diesel. So far, this one has left me nothing to worry about.

Couldn't live without a turbocharger on a truck. the get up and go performance is unmistakeable. On a tractor, not so important.

Wrong. The turbo spins a little faster pumping the thinner air. This enables them to hold speced boost pressure. What part do you think wastegates play?

The engine management control system can allow the wastegate to increase pressure to a point but at high altitudes the air is so thin that the wastegate can't compensate any longer because damage from detonation problems occur.

Will you notice any worthwhile change in a 33 hp tractor at 1k feet? No.

So, one more time, you want a turbo, get one. I don't. You like the whine, the extra parts, the extra stresses on the engine AND the extra initial expenses for a couple of hp, go for it.
