There's been a few threads lately talking about weight, weight transfer, and dimensions of tractors with certain attachments; hopefully this can be a go-to source of info for various x7 tractors when people need info for sizing a trailer, building a shed, etc. Feel free to add any and all info you might have!

I spent some time at the local big truck scale today to get things started. The following is info from an x748 MFWD with a 45 loader, click-n-go weight bracket, full tank of fuel, a 250 lb operator (when noted), and six 42 pound suitcase weights hanging out back. This particular scale moved in 20 lb increments; some of these I just measured the front axle for differences once I did the original test, then did the math (that's why some are 10 lb increments).

In order to find a good average load (towards the high end of an average load for most people), I scooped up a full bucket of 1" clean limestone and weighed it at roughly 450 lbs; since that's a potentially messy load on a scale, I substituted 11 suitcase weights in the bucket (42 lbs each) which comes to 462 lbs.

This is the amount of gravel (hard to tell, but it's basically level across)...



The tractor looked like a toy on that big scale...



-----------------------------------------

Loader alone: 480 lbs

Tractor alone: 1180 lbs

------------------------------------------

Tractor alone w/ operator (no rear suitcase weights):

Front axle: 610 lbs

Rear axle: 820 lbs

Total: 1430 lbs

-----------------------------------------

Tractor alone w/ operator (6 rear suitcase weights):

Front axle: 550 lbs

Rear axle: 1130 lbs

Total: 1680 lbs

------------------------------------------

Tractor alone w/o operator (6 rear suitcase weights):

Front axle: 510 lbs

Rear axle: 920 lbs

Total: 1430 lbs

------------------------------------------

Tractor w/ operator and 45 loader (empty bucket / no rear suitcase weights): 1910 lbs

Front axle w/ bucket ~1" off the ground: 1140 lbs

Front axle w/ bucket ~2' off the ground: 1220 lbs

Front axle w/ bucket at full height: 1140 lbs

------------------------------------------

Tractor w/ operator and 45 loader (empty bucket / 6 rear suitcase weights): 2160 lbs

Front axle w/ bucket ~1" off the ground: 1060 lbs

Front axle w/ bucket ~2' off the ground: 1100 lbs

Front axle w/ bucket at full height: 1060 lbs

------------------------------------------

Tractor w/ operator and 45 loader (full bucket / no rear suitcase weights): 2370 lbs

Front axle w/ bucket ~1" off the ground: 1900 lbs

Front axle w/ bucket ~2' off the ground: 2380 lbs

Front axle w/ bucket at full height: Not going to happen.


------------------------------------------

Tractor w/ operator and 45 loader (full bucket / 6 rear suitcase weights): 2620 lbs

Front axle w/ bucket ~1" off the ground: 1800 lbs

Front axle w/ bucket ~2' off the ground: 1950 lbs

Front axle w/ bucket at full height: 1800 lbs

Hopefully this thread will help some people; there's also some things to be learned from this as far as weight transfer goes (like why the steering isn't very good when you're in float mode with a blade and there's 6 suitcase weights out back.. the front axle is 100 lbs lighter). There's more to come later as time allows and attachments get changed; once again, please add your own info since different people have different attachments/accessories (overall legth, weight if possible, height if applicable (cabs), etc). :trink39:

Any thoughts of making this into a Sticky?

As we have all asked questions regarding ballast and it's effect on weight transfer this helps demonstrate what Tudor and DP keep trying to explain.

Thank you for the information, I bet it was a lot of fun gathering it and playing with the big scale.

Thanks for going through this analysis, DP! Very interesting. :Tractor2:

Outstanding project! This is great!

Now, where did you get 17 suitcase weights to run this study???

Thanks, fellas. More to come as time allows. :trink39:

They've accumulated from good deals over the years; I've been trying to pass the good deals along to some locals lately so somebody else can get some good use out of 'em, but no such luck yet. The last count was 26, but I only regularly use ~15. :hide:

I did find out that 19 weights will fit side-by-side in the loader bucket, but the loader says "get lost" when you try to lift 'em. :biglaugh: :dunno:

Yah got the wrong colour tractor for that kinda work! Try red!

Great thread DP!! It's nice to have definitive answers to some of the weight questions, instead of generalized ballpark figures.

I just stuck it! That should save us some typing in the future. :trink40:

Great info DP! This has definitely been a challenge for some to explain and others to understand (or even believe).

I really like the Tractor & Operator #s compared to the Tractor & Rear Weights #s. You and your weights are the same (well you have much more value than they do) so it is interesting to see how 100# of weight transfers from the front axle to the rear axle as you move that 250# from the seat (above the rear axle) back to where the suitcase weights are located. The same total weight but a different balance front to back based on the leverage of that 250#. Guys like Rob and Roy with their weight even further out back on a 3pt hitch would see this difference more exaggerated.

I took your info and put it into a spreadsheet to help me see it and thought I would share it.

:thanku:for taking the time to put this together!:trink39:

Diesel Powered and everybody else, is there any serious objection to moving this thread to the Back Yard Round Table where more folks will get a look at it? Many members don't spend a lot of time outside their own brands or interests and could easily miss this information tucked away in the JD sticky section.

This is a great resource for the effect of weights on balances for any colour of FEL and POENY's spread sheet really makes it easy to understand what is going on.

Bob, I understand what you would like to do, but if you go back and read the first couple of lines of this thread, DP wanted to start a thread with all kinds of dimensions regarding the X700 series. He started with the weight issue and hopefully others will contribute with lengths, heights and widths with different attachments.
IMO it should stay on the John Deere Forum. :fing32:

Ditto to what Mike said, but what about starting a more universal thread like "understanding weight transfer" or something along those lines? I'd be willing to contribute my scale data if that helps.

Understood. That's why I asked.

Thank you. I'll do it that way later tonight with a link back to this thread.
