Have I got this figured out?

I guess I am

You know, after all this talk, I went home last night and looked at my 7040 and it has four different settings for the front and rear wheels.

After I read your first post I was actually going to reply that the 7040 does have adjustable wheels, but you figured that out before I could post!!

Also the larger Kubotas that may actually get used for row crop have an axle spacer kit that widens the 4wd housing to give you 4 more wheel spacing options. I don't know anyone who has ever bought it. The 2wd kubotas have adjustable axles just like any old 2wd tractor.

My friends TW-25 only has few wheel spacings, 4 I think. Doesn't stop him from planting 800 acres of corn.

Yeah this is a pretty irrelevant thread. Seems kinda like trolling to me. If the market demanded more wheel spacing options, I think the manufacturers would make them?

I don't think it's an "irrelevent thread", but will agree it's relevency is with a somewhat limited audience. Adjustable tread width on compact tractors is very limited, and probably for good reason. It just isn't a nessecity. There are multitudes of utility and conventional rowcrop farm tractors still on the market. If a person needs that option, he should choose the model and brand that fits his needs. The typical compact buyer and/or non-rowcrop farmer probably couldn't care any less. However, for a few of us, it IS an important factor in choosing tractors

Of limited interest, maybe, irrelevant no, and as far as trolling I can't read people's minds, but we are in the Ag Tractors forum.

I know it was relevant to the Kubota dealer last year when I told him I had 3 other tractors set at 68" and I needed the 7040 to be the same or very close to it. He told me he had lost two sales recently because of just this concern and questions about tire options.

KUBOTA 7040 4WD front = 55.9"-59.9", rear =55.9"-67.7"
JD 5325 4WD FRONT =52.8" - 75.0", rear = 55.7"-74"

My understanding is that the Kubota spacer option someone mentioned is only for the rear, so is pretty much useless; I think it's mainly for the 2wd versions so you can line the back up with the front. It may be that Kubota doesn't want the front widened out on the 4WD because of extra stress on the axle components. I believe I read somewhere (on this site?) that the Kubota axle design is different.

I looked at the manual for a 3X16" plow I have and the wheels have to be set at 68"-72", so no good with the Kubota. But I guess real farmers don't use plows anymore either

I liked a lot of features of the Kubota and I'm glad you're happy with yours but for me the machine was too inflexible.

If the minimum required for a 3 bottom plow is 68" I think the 67.7" spacing on the Kubota would be close enough. The plow won't recognize the .3" difference.

Most of the utility tractors have adjustable rims but when it comes to compacts I really do not see adjustable rims as being a major item. Most of the time the owners either set them out as wide as possible or to where they are comfortable with them. So if the vast majority of the compact owners do not need adjustable rims why would any of the compact makers worry about it? Most utility tractors have enough adjustment to their rims to suit their owners except maybe the Kubota line but I don't know enough about their product line to say.

I understand what you're saying, 3/10" wouldn't make any difference.

But the problem with the Kubota FWD M-series is that the front axle has only 4" of adjustment. The widest it can be set is 56.3" on the M6040 and 59.9" on the M7040. The 67.7" you refer to is for the REAR wheels only. Even allowing for the fact that the front tires are narrower than the rear and you could cheat a little by having a narrower front setting it still wouldn't work correctly.

I see what you are saying, as I said, I don't know much about the Kubota utility tractors but so far they seem to be the only one that doesn't have a lot of adjustment on their utility tractors

Now hold on!!!!
Just what is the critical measurment here? Is it inside track? Kubota is using centerline numbers and it is a little differant if you are talking about a 9.5" Front tire or a 16.9" Rear tire. My tires are set at min. front setting and max rear( Kubota spec for a FEL ). My inside track "appears" to be the same (F&R) I did not measure it. If it is outside track then it will be off( How could this be). Please correct me if I am wrong on this.
My plowing experiance is limited to a JD Model M single bottom two way plow that was very easy to set up as Dad said do this and it will work!! He was right!!!!
