WaxMan's Modifications to the 2013 Grand L 3240 cab

[ericher69]

Waxman;

Is it a possibility to keep the large wheels for the odd time you will need/want them?

Still the cheapest/most practical solution IMHO.

As for the BH; I would keep BH92 as to get max use and resale value in the future.

Going Deere will leave you Green with envy for Orange...

Are the L3800 tires suitable for the extra weight of the l3240 cab tractor with a heavier loader that will lift more?

I would also keep the BH92 because you will gain a minimal amount of space with the BH77.

 

[WaxMan]

Go with green.

I'll never buy another Kubota.

That is still an option Fred.

Well I'm going to chime in here and I know Waxman is going to completely come unglued but I'm going to attempt to save him from himself. What you are attempting to do is totally unpractical. These machines were designed with a certain tire size in mine and the drive-line was designed with the wheel size and tire size in mind. If you change the rear tire size you'll have to change the front tire size as well to prevent drive line binding when in four wheel drive. Ground clearance will be a huge issue.

Yes you may have level ground now but sometime in the future you may need your machine to operate in an environment that is not so level and because of your altered wheel size you've then limited your machine to operate only on level surfaces.
Putting the smaller wheels on will give you a horrible gap between the rear fenders and the top of the wheels. Yes a filler gap may mask that issue but it will take a nicely designed cab and turn it into something it wasn't meant to be or look like. The back hoe will dig in because it's lack of height. There's to many minus's to make this a viable project not to mention you just spoiled the resale value of an otherwise nice machine.

I know you hate any criticism especially from me but just don't do mods for the sake of doing mods. As I told you before. Keep them practical.

Ha, You would be the last person I would take any advice from.
Or is this just another attempt by you to get another one of my popular threads shut down, that seems to be a pattern with you.

You told everyone on TBN

Well to be honest I never noticed. I don't see his posts, don't go to his threads. There's approximately 230.000 members on this forum and I have one and only one on my ignore list and I bet you can guess who that might be. I wish he would do the same.

please go readjust your settings and keep things you say and post truthful.

After what you said about me at the end of this video was very unnecessary about the email and my inclinometer, I have no need for you.
I have no respect for you. I don't have time for jealous petty people as yourself.

Why don't you watch what you said again.
My wife thinks when you're not being truthful you rub your ear, because my wife and I both know you were not being truthful about my email in this video, and so do you,
Sorry Shorts, you made your bed go LIE in it.

Why don't you start your own bashing WaxMan thread and post all you want about the Mods that I make that are not practical. Please do not reply, just move on. This has nothing to do with you, No one mentioned your name.

Waxman,I understand your situation.Kubota doesn't make the tractor you would like to have.I am the same.My ideal tractor would be an open station B series with the features of a Grand L.It doesn't exist so I make do with my B2620.You are not content with "making do" so you are trying to find a way to have the tractor you want.I wish you good luck and await your solution.

Thanks kcender
Got the tires today and will report my finding. I have many options tires, backhoes, other tractors. I needed to get the tires to help me decide everyones comments and opinions are welcome to help me decide. Good or bad I'm a big boy.

I picked them up today ericher69, The wheels and tires are 2100.00
No cost to me to exchange them so I have them on and will continue to drive it around and think about which way I want to go over the next week or so and see what I think.

Yes the tires are more then suitable for the weight, they are much larger then B series tires
They are L tires.

Yes keeping the BH 92 is definitely an option that is still open.

I went to the dealer today picked up the tires and installed them. The tires are ok to use on this Kubota, it was checked out before I bought the tractor last year and OK'd to use.

These machines were designed with a certain tire size in mine and the drive-line was designed with the wheel size and tire size in mind. If you change the rear tire size you'll have to change the front tire size as well to prevent drive line binding when in four wheel drive. Ground clearance will be a huge issue.

It is a Matched set from L 3800 That means "4 tires" some people like to butt in but have no idea what there talking about ,ps

The way you tell if the tires are OK
Is to put it in and out of 4 wheel drive while on the go. I tested this myself today driving across the yard in medium high range, I can shift in and out of 4 wheel drive at will without stopping, NO grinding or hard to move the lever. Slides in and out better then it ever did standing still. If the wheels were not matched you would not be able to effortlessly do that The gears would not mesh. So not only did Kubota confirm this so did I. Kubota has 4 different size rear tire option on the Grand L 60 alone.
At Kubota today there was two New of the same size large open tractors L something side by side one had R1 and one had wide turfs that were at least 5 inches shorter and a whole lot wider. I don't believe Kubota redid the drive line on the two same tractors.

If someone has information that they know (facts) the driveline will blow up with these tires. Please post the site or facts to back it up Lets not turn the thread into speculation and guessing what will /could happen.
Lets keep it about the looks, the lower 11 inch clearance and other drawbacks you can think of.
If everyone says forget the smaller tires and I decide that too I'll just bring them back. If I want to keep them I will bring the others back.

The tires if I want them would be an even exchange. I bought the tractor with these smaller tires on and got cold feet from one mans opinion. Going with the smaller backhoe will have a cost.
I really don't need the large backhoe around all the time.
The smaller backhoe would be much more manageable.

I think the smaller tires will mess everything up. First the ground clearance is going to be lower. I know it still higher than a B2650 but the 3240 is longer so it will be easier to high center. You loader lift height will be lower of course. I am not sure if it will mess with the loader in any other ways. My biggest concern would be the gearing. Your top speed may be as low a 8 or 10mph. That may not be a big deal if you don't drive on the road but now your high range is going be like your old medium and medium will be like low and the tractor will crawl in low. So the tractor is not going to perform properly. I would also be concerned about the gearing when in 4wd. Ideally you want the front tires to be turning within 3% of the rear tires mph.

You're right BULLITT about the different speeds it is lower in every gear, But I'm not sure that is a bad thing. You have a 4240 mine is a 3240 which is a little underpowered as it is as I have been told.
Being geared a little lower might make up for some loss in power that your larger model has.

No difference about the loader even my electronic level indicator still reads level on the ground. I don't think I even used the loader at is maximum height so I don't think 2.5 inches less high will matter. I address the gearing in my last post. It's a non issue unless someone digs something up to the contrary , I'm not stupid I will listen to facts. I don't want the small tires that bad to ignore something.

The front axle ground clearance is 14 inches,
This heavy duty BH92 backhoe subframe hangs down more then a B77 subframe.
Anybody have a picture of a B77 subframe on any tractor? I believe its a lot smaller than this one and won't hang down as much.


My 3240 with small tires - front axle 14inches, double step 11 inches, rear axle housing 14 inches
John Deere 3033R My Other tractor of choice Front axle ground clearance 10.9
Front axle clearance, in. (mm)
276.9 mm
10.9 in as per the John Deere web site
Kubota B3350 ground 14.5
Kubota B3030 ground 14.0
Bx ground 8.9

So the Grand L with the smaller tires is right in line with the B machines
Except the B series does not have a Grand L cab or HSTplus

I'd just clear some more room in the barn and keep the Kubota, it is a beauty. The more tractors the better.

Waxman glad you are experimenting with the tires! I think you should get rid of the massive backhoe too since you aren't using it much. Much better plan than going with Deere!

The tires and four wheel drive are all about ratios. The front tire to rear tire diameter ratio has to be the same as the stock tires. This way no matter the tire size, as long as the ratio is the same you are good! The tire sizes Kubota offers for the L60 you mentioned would all have the same ratio.

Your test method should also include disengagement of four wheel drive. Drive in a straight line, engage four wheel drive, drive for maybe another 100 to 150 feet and then disengage 4wd.... If the 4wd lever moves easily to engage and disengage you should be good to go! If it is hard to disengage the front and rear wheel ratio is wrong for the tractor.

Good luck! Very interesting posts. I for one think the L40 looks awesome with those smaller tires! (0:

I could care less about his opinion or criticism, what I don't like is when,
He comes off all condescending and acts like he is an authority about something he absolutely knows nothing about.

As for the ground clearance being HUGE issue as he says ,
The hight is 2 1/4 inches lower at every point. 2 1/4 difference on a tractor that specs is above 14 inches minimum ground clearance. I wouldn't call that huge.

As being able to put smaller tires on ,

Theses are the Kubota factory tire options for the new Grand L 5060 As you can see different tire sizes options on the same tractor.
The hight difference between these two factory options is almost 9 inches different in height. 8.9


If its good enough to go on a New Grand L 5060 Its good enough to go on my tractor If I choose to go that route.
If I was able to go back and build a Kubota Grand L 3240, Im sure the options are the same.
So bacicly other than a turf tire The size I'm putting on is a Factory option, shorts know it all,

Thank you PapaPerk I agree with everything you have said.
