If that engine is 75lbs lighter, I have to wonder... Is it Cast Aluminum? If so... Glad I bought my 2010!

 

Good question.

Here is the Yanmar info on the 0.9 liter 3TNM72 engine. Note that they call it a "MINIMAX IDI Series -- Industrial Diesel Engine."

And here is the Yanmar info on the 1.1 liter 3TNM76 engine. Note that it is called an "IDI" engine, but not a "Minimax."

Yanmar describes the "Minimax" engine series as follows:

Minimax: Big power from a small package offers Tier 4 compliance right out of the box. The first ladder frame cylinder block in its class allows the MINIMAX series to produce less noise and vibration than competing engines. Its perfect size means ease of installation into a variety of equipment.

Again, I do not KNOW that the 3TNM72 Minimax is the engine they will be using in the 2011s. I just can't find another 0.9 liter engine on Yanmar's website. But that doesn't mean there isn't one.

 

Assuming is the right engine for the new 2011 model, here's a side by side comparison I made.

From looking at the Yanmar PDF we can assume that the engine block is aluminum.

One other thing is the 1.1 liter as a auxiliary drive on the PTO.

 

I guess these engines run really cool. I've never seen a 70 deg. thermostat.

 

Thanks stladrill.

I did notice that JD is still spec-ing a 40 amp alternator on the 2011 diesels, so that's good.

Sorry, but I did not quite understand what you meant by "One other thing is the 1.1 liter as a auxiliary drive on the PTO." ??

Some more info about Minimax engines here:

Article about Minimax Series

and here:

Yanmar Minimax Engines

It sounds like the Minimax series has some good features (lighter weight, higher density power, quieter), but it also sounds like the overall purpose of the design was to cut costs.

I stress that we do not know if the 3TNM72 Minimax is the engine for 2011.

If you check the PDF for the 1.1 in the PTO section you'll see "Aux Drive, 9-tooth w/SAE 2 bolt “A” Flange"

 

rcurtis,

Sounds like a typo. They come with a 170 degree thermostat, 180 is optional.

It sounds like the new Minimax will be a good engine, but.... WE KNOW how good the cast iron existing Diesels are. They have been proven over more than 2 decades. I wouldn't be an "early adopter" and I'm glad I have the 235lb hunk of cast iron that is the 3TNV

 

...I wouldn't be an "early adopter" and I'm glad I have the 235lb hunk of cast iron that is the 3TNV

Some of us might not have a choice if we can't find a left over 2010. This change sort of blind-sided me. I was not expecting a different engine in the 2011 models.

I still haven't been able to confirm that the 0.9 3TNV72 Minimax is cast aluminum. They talk about a "ladder frame cylinder block", but I have no idea what that is.

 

Interesting. Will the X series under go the new updates, and model number changes just like the entire JD line up??

 

This change might be emissions driven (e.g "Tier 4 compliant"). The more restrictive diesel emissions that already impact OTR trucks is being phased in to stationary applications and driving down toward smaller HP engines. I assume this is also happening on the off-road/industrial diesels as well which I would assume begins to catch those that end up in the x700 series.

 

I don't so much mind the smaller/less powerful engine. A bit quieter would be nice too.

What concerns me is this statement by the Yanmar guy in the article I linked to above:

"One of the things we're most proud of at Yanmar is that we make heavy-duty engines," said Jeff Williams, manager, Sales and Marketing at Yanmar America, Buffalo Grove, III., the North American engine operation of Japan's Yanmar Corp. "But in reality, not every application needs that.

"So we looked again at the conditions in the markets we were targeting and we looked at the competition and what they were selling into those markets. We decided that we could make engines that could be a little more price competitive in some of those markets where the engines are almost more of a commodity. These [Minimax] engines were designed from the ground up to do that."

If the X700 diesels are now coming with a less heavy-duty, less potent, less expensive engine, then that should be reflected in the price. I'm really hoping someone knowledgeable will chime in and tell us that JD's not using the Minimax engine, but a different 0.9 liter version.

Of course there's more to the price than just the engine. If they reduce the cost of the engine, and then "eat up" that savings by offering more standard features, then they'll likely attract more customers. For instance, if they can save on the engine and offer something like a standard rear PTO and 3pt hitch, that's probably going to make their products much more competetive in the market.

And, if the previous Yanmar engine exceeded JD specs by 50%, but the new cost-reduced engine only exceeds JD specs by 25%, then it's likely that the customer isn't losing value or noticing a difference.

It would be interesting to see the rebuild interval on the two engines compared. If the mean time between rebuilds has shrunk from say 2000 hours to 1000hours, then the customer has indeed lost value. (although it's a long-term loss that the average customer might not understand.)

 

Hopefully JD won't rename them LA 700 diesels. :hide:
Don't shoot, the 2010s are still awesome!

 

The Google is strong within you Jedi!

 

Sounds like the X700 Series is becoming a cheaper Garden Tractor. Everything is becoming disposable, sad but true.

But probably not less expensive. :fing20:

 

Sure, yeah, they could make up the "value" in other ways, or they could pass the savings on. There's no indication of the former yet. Maybe they'll pass the savings on by holding the price at 2010 levels?

And it's quite possible that the beast was already "over-engined". Still, it's nice to have the extra "grunt" in reserve, in my opinion. But it may well turn out that most of us can't notice the difference.

Funny thing is, I just spoke to two dealers today, neither of whom was aware that the engine was changing for 2011. They weren't aware of ANY changes to these models, so either they are very uninformed or we probably won't see JD packaging the rear pto and 3PH, either. Unfortunately.

Same here, I stopped in for a heart to heart with the salesman that attended the seminar on the new 1026R, and brought this up. He called bullspit. But I got some info (and a looky at some photos) on the new 1023E and 1026R models. :fing32:

 

He had no knowledge of the engine change for next year. His response was "Bullpuckies" or something close to that.

 

They're probably not allowed to say or acknowledge much until Deere and Co has a low enough supply of the 2010s...

 

That shouldn't take too long, the dealership I was at has received and prepped seven X748 or X749's in the last week according to the salesman. When he stated he wasn't sure what was driving that, I asked if he had ever heard of MTF. :banghead3:banghead3:banghead3:banghead3:trink39:

Although 3 X749's in the set-up shop (2 with cabs) was a cool site.

 

So when am I getting my commission check?

 

Some questions relative to this thread -

- When is the official \ published release date of the 2011 GT models?
- what date did they update the website last year with 2010 GT models?

- If they were changing engines on X7xx series - wouldn't the dealers all
have to be trained and ready to service them? so, wouldn't the dealers
already know if new engines were coming or not?

- Would deere really put anything but a top line strong engine in their ultimate
tractor line?

I am relatively new to the forum - so sorry of these are redundant or irrelevant questions.

 

Good questions. Don't know the answers to any of them, either.

First, let's keep in mind that we don't know yet whether the new 0.9 liter engine is the Minimax being discussed.

As far as whether JD would put anything but a top line engine in these... They may feel these engines are comparable, or represent a better value/fit for what the tractor is intended to do.

But I think there is a guy over at Yanmar that is really regretting how he characterized the Minimax line of engines in that press release/article I quoted above.

 

Regardless of what engine is used, it has to pass JD testing. No way JD would jeopardized the durability of the X7's. So I wouldn't worry there.

I do think that the current Yanmar is probably three times the engine that an X7 needs in reality. But as has been said, if Yanmar is only offering the new engine (to meet emissions), that's also all JD has to offer as well. I have full confidence in both JD and Yanmar, so I wouldn't worry.

That is why we are ok paying Three times as much money to get a real tractor, errr umm.. a heavy duty garden tractor! :trink39:

 

I thought he meant the Kawasaki engine, it runs on gas.

Rob

 

Yeah but it's like the SuperMan of gas engines! I'm sure if you take off the air cleaner you will see the S logo! :greendr:

 

Why doesn't John Deere put the diesel in the other tractors, like the x300 on up.

They have a lot of tractors they could put it in, is it on the edge of not being effective with the x700's?

A few years back they put in the 430.

Now they have the 500 series and up to the 720 and x728 with no diesel, is it the money or the engineering to make it work right?

I have wondered about this.

Rob

 

Sales... In the smaller markets, consumers WANT Gasoline engines, it's the same reason we don't see a lot of 50 MPG Diesel cars in the US... The rest of the world gets them!

Consumers drive Trends and in the US Petrol is the Trend. And because of that, Petrol engines have been refined over the decades and you have some pretty darn good ones out there. Some of us don't mind spending a little bit extra (it's only a grand in the scheme of things) to get the diesel because it's not a hassle to deal with an additional fuel type. I actually pay less for a gallon of Diesel than I do for a gallon of Gas and I don't have any other small engines around here that use Gasoline except for the power washer and that's it.

 

It is confirmed the new engine is the 3TNM72....

One thing is that the JD website is showing the engine as "3TNM72-BJLT", whereas the product page for the engine that we've been looking at calls it "3TNM72-AMW".

Anybody have any thoughts as to what the suffix "BJLT" or "AMW" means?

IMHO it's the John Deere package, upgrade alternator that we see and other feature required by John Deere.

 

I didn't see anything on the BJLT but did notice that the 3TNM72 engine was available (not in North America) two years ago. http://www.allbusiness.com/legal/environmental-law-air-quality-regulation/11708873-1.html

That's good to know, it mean the engine is field tested for two years.:fing32:

 

I just looked at John deere engines, and the yanmar is not offered on the bigger diesels, can somebody explain why this is, just wondering.

Rob

 

All the bigger Deere's used to be Yanmar as well. JD is cutting it's ties with Yanmar and moving engine production in house. My guess is they don't like being dependant on outside vendors for motive power. It certainly has nothing to do with quality, because Yanmar has the track record.

 

From what I understand Deere builds their own engines for the bigger tractors. Could be wrong.
