While looking for some info I came across this part of the Deere site I had not seen before. Might be old news to most but I found it interesting and if you are thinking "I want an X7xx tractor but used is for me" this might help you figure out what the #s mean. It helps me when other models are referenced here.

POENY,

You are the man! One wonders why JD doesn't make the info available like this?

Forgive the nitpick, but X729 and X749 came out a couple years later than the other X7s. I think their first model year was 2008 -- maybe somebody can confirm?

Also, I added a note to my previous post, where I suggested calling the X729/749 drive system "AWD" (for full-time All-Wheel-Drive) rather than 4WD, since that was a fairly significant change to the drive system.

How does 2008 sound for X729/X749?

I missed the AWD thing earlier. Makes sense for X729/X749 and current X728/X748 tractors but not the original X728/X748 tractors. I struggled with all of engine changes in some models (like the 2011 X74x update and the X595 update from 3TNE74 to 3TNV76) too.

Any thoughts on how to account for this? I could add new lines for each change but it might get busy. I might try it though it is only copy/insert and editing (my main problem).

:thanku:

I'm not great with spreadsheets. You are doing a great job with it.

It would be kind of nice to get those other engine/drivetrain changes though, just to make it really comprehensive.

Would it be possible to "split" the box beginning just to the right of the model name (i.e., beginning with "Drive") all the way across to the right, and add the different engine/drivetrain info in a way that corresponds to the model year?

But I could see where even that might be tricky. For instance, the X748 will have different drivetrain (4WD and AWD) and different engines (3TNV76 and 3TNM72), but these changes were all introduced in different model years.

Looking good! I like it sorted by model number, but thats just my brain's organizational methods, which wouldn't be the same for all. :fing32:

I'd really like to have a spreadsheet put up here as an attachment.

Just one thing, according to JD, the X585 has 25, not 23 HP.

Hi!
Nice sheet!

Could you add a column with information about hydraulics capabilities?

Greetings.

I'll post it as an attachment when it matures a bit more.

I agree. For just looking stuff up the model sort works best. As more rows get added to account for year to year variations within a model this may be more important.

I do like the other sort or maybe something similar that I have not thought of yet to refer to when I see a post on a model I'm not as familiar with. Seeing that the X495 is almost the same as a X740 without having to scan and compare all of the data each time is nice.

Maybe someone web developer type can put it all in a database and give us a couple of different web page views of it.

Absolutely FANTASTIC spreadsheet! (And I prefer it sorted by Model #)

That's a good point - as the 4wd/AWS machine have higher-flow hydraulic pumps. Someone should double check the tech manuals and get the flow rating for each. I think the 2wd is @ 4gpm, and the 4wd/AWS @ 5gpm.

The info I have says the 2WD=4.65 [email protected], and [email protected]

This is what my X748 manual shows. It does not change as the engine changed in 2011.

Here is a "by model" update. I tried to get everything mentioned but ... I took a shot at the year info.

The following is a page from the parts catalog I ordered when I got the tech manual. If the serial # to year info is available it could be added to the spreadsheet. Does anyone have a source for this info?

POENY,

Not sure. But the info you have there is nearly identical to what I have, so I think that's a confirmation - at least for current models.

In any case, I'm not really sure if this is what Gifti was asking about. I actually thought he was asking which models have hydraulics. By "hydraulics" I thought he meant which models have the hydraulic coupler valves, for hooking up loader, blower, blade, etc.

My understanding was that all models do, except for the X700 and maybe the X465? Anybody have other info?

P.S. The new table looks great. I like both formats (sequential model numbers, and the "grouped" version you originally did. Also, I think the X728 needs an "AWD" for the 2009- models.

Yes it did. I updated it but will hold off on posting an update for a while. :thanku:

Yeah, that should be the same for all model years of X5 and X7 models. I believe the logic I heard was that loaders would mainly be put on 4wd models, so they got the larger pumps. And as a tangent, since loaders are not approved for all-wheel-steer machines, they get the standard pump even if they have the hydro 4wd. Gas or diesel makes no difference.

So:

2ws / 2WD = 4.5 GPM
2ws / 4WD-MFWD = 6.0 GPM
2ws / 4WD-HFWD = 6.0 GPM
4ws / 2WD= 4.5 GPM
4ws / 4WD-HFWD = 4.5 GPM

And I think you are correct that all models get the 2-spool valve standard, but only the X465 and X700 are lacking the couplers.

Thanks! You are right! Just add a column where you can see if the tractor-model has basically possibilities for hydraulic attachments. (Front, Rear, both, additional equipment you need for hydraulics optional available, ...)
Additional you can add a second column to define the power of the hydraulic system (GPM)... but I think this is very specific and hard to find out for all models.

Thanks in advance,
Gifti

I'm just throwing out to add the pump specs, because if someone is looking for a tractor specifically to use the hydraulics (loader, log splitter, etc), knowing which tractors have the most hydraulic capacity could be a factor in their decision.

That's a good point.

Regarding the pump capacity on AWS models, the info I have indicates that the X749 has the same pump capacity as the X748. That is different from what POENY has posted. Any way to confirm this one way or the other?

The reason I ask, is this is actually a fairly major difference that is rarely pointed out when discussing the pros/cons of different X-series models. I have been under the impression that X749/X729 was every bit the tractor as the X748/X728, plus AWS. Not so, according to the info POENY posted. That's a significant difference in flow rate for operating hydraulic attachments like log splitters, etc.

EDIT: Actually, in studying the info I have more closely, it DOES NOT indicate higher rate flow for the X729/749. So, I would take the info provided by POENY and ET as definitive.

Wow, that corrects a mistaken impression I've had for quite some time. I wonder how many others are unaware of this distinction?

Also, I wonder if the lower rate flow would have any effect on things like the transaxle hydrostatic relief or the implement relief valves?

I don't have another source. My data was copied from page 225 (Power Train - Hydrostatic Specifications) of the technical manual I bought in late December 2010. It is named "JOHN DEERE SELECT SERIES TRACTOR X7-TM2350.pdf" and has a date of November 2010.

Nothing in this section of the manual differentiates specs based on the engine version (3TNV76 or 3TNV72) so the values are probably accurate for similar X72x models and I'm guessing the X700 as well. If the TT K92 has not change based on JD models changing these values may be accurate back to X4xx & x5xx models as well.

Does anyone have a tech manual from a X4xx - X5xx tractor they could get this info from?
