L2800 Position Control (Jerky?)

[canoetrpr]

Kubota is a bunch of dolts best I can tell. Penny wise and pound foolish is what my grandmother would have called it.

I suspect, as the other poster did, that they are really trying hard to create a differentiation between the L3400 and the GL 3240.

If you take the time to look the GL more than makes up for the difference in price IMHO. However, to Joe the tractor buyer, he's looking at HP more than anything else. I suspect they end up selling A LOT Of L3400s vs. the bottom GLs for this reason.

Again - what a bunch of dolts if they have gone back to the jerky valve.

Bigger dolts if they are now trying to stick to the economy tractor line Way to make someone who just dropped 20K on a tractor feel good.

BTW. if it was me and I wanted to make a point, I would replace the valve with an improved valve - heck get the dealer to do it and pay for it and then take Kubota to small claims court.

If you lose - you lose. But that might be the quickest way to get it resolved. Pay for it but hope to get the money back.

Here are some pages from the L2800 manual for the 3ph. Hope it helps.

After looking at a good population of malfunctioning valves on the L2800/3400 the operation appears to be a safety hazard which goes far beyond the functionality issue.

With that kind of violent shaking going it is a safety issue.

Kubota should be seriously concerned about this potential failure mode.

My old 8N has a better control that this tractor.

I agree with the others that there is a serious problem with your 3PT on your tractor. It doesn't suprise me with the response you have received from Kubota on the matter. This type of respose seems to be the norm within every large company today and I bet you will find simular posts on the Green/Red/Etc forums on this website. Talking lawsuit will do nothing for you as the only winner will be the lawyers and generally when you use the lawsuit word it will just harden their response.

If you are looking for real results, you need to reach the right people. Look under the Investor relations for Kubota Corp and you will find the names of the Board of Directors. You can assume that they have an e-mail address and all you have to do now is figure our the right combination. I have tried to find you that combination by searching for other e-mail addresses within Kubota.co.jp but I have not found any of yet. It could be First_Last@kubota.co.jp or First.Last@Kubota.co.jp You get the picture. Send a well worded e-mail to as many combinations of these as you can and hope you will hit the mark.

I have done this several times and each time, the response is stunning. Also include the people who have been telling you that there is nothing wrong and there is nothing they can do for you. I find this is key because most of the time thay may know who these directors are and they don't know if you were sucessfull in reaching them. This causes them to change their tune even if you did not get a response from them. No one wants to look like an idiot to their boss. I would aslo make sure you post your YouTube video.

We had a serious support issue with Dell in the past with one of our clients. We had an in warranty laptop fail and Dell informed us that the part will be 3 weeks away. The laptop had 7x24 support so this was a farce. We called our Rep and complained to a dozen people. Nothing. I send an well worded letter and tried the combinations of the Board of Directors with e-mail and I hit send and 10 mins later I received a phone call from some response team in Dell. We had the part the next day.

Here is what ther is on the name of the board of directors for Kubota JP. You may have issues with the language barrier but I would assume that most of these guys can read and write in English

I should not post this as now everyone will use this tactic until big corporations start changing the director e-mails to something cryptic. I will figure that out as well I guess.

Cheers and Good Luck!

MacTractor makes some great points.

Instead of an email, you might want to send a snail mail registered letter to the Kubota USA executives and perhaps CC the Japanese folks.

Make that a Certified letter...

I have not read every tread (on vacation) but I have to say that for kubota to swap out good valves and put BACK jerky valves - is criminal... maybe not with the letter of the law but for common decency... I will not recommend kutoba again.

Feel free to copy my signature to let everyone know who is coming to this site for information about the problem...

Hi Everyone,

Just thought I would let you all know that I too have just purchased a new 2008 (I think ?) L3400 and am struggling with the jerky position control on my 3PH. The Kubota dealer who is working on my tractor has replaced my position control valve and it is still very jerky. He then setup another new L3400 and it too is doing the exact same thing so now he is saying that they are all this way and there is nothing wrong with my tractor

I would like to know what the actual solution to this problem is.

Question: Has anyone had their tractor "fixed" such that the 3PH is no longer jerky in operation (lifts like a normal tractor) ?

If yes, do you know or can you find out what the Kubota part number is that was used to replace your valve etc...

This whole experience has really shaken my confidence in Kubota. I have yet to return my "New Customer Satisfaction" questionaire. I really want to be a happy customer and good reference but Kubota needs to own up to the problem and resolve it soon.

Thanks to all of you for sharing your experiences, it is comforting knowing that we are not alone in this problem.

I'm with you Toy Camry. I too would like to know what to do to fix my own tractor since Kubota won't.

Hi Everyone,

At this point I wonder what jerky means to you. When I got my L3400 in August of 2005 the 3PH raised in increments of about 1 inch. Raising the woods RD7200 mower made the tractor jump quite violently. After the valve was replaced it raised in increments of about 1/4 inch. It still jerks a bit but not enough to feel like something is going to break like it did before.

It is NOT silky smooth like my old Ford 1910. I don't know that any L2800/L3400 is perfectly smooth. I'd be more unhappy if I had to grade with this tractor. I use the 1910 for that.

With no implements on the tractor try this test. Put the 3PH at mid point. Hold a ruler from the ground to the edge of the 3PH arm and make note of the scale. very, very slowly move the control lever to go up. when the arm jumps up look at the ruler again to see how much it jumped. If the jump is in the range of 1/4 inch you probably have the same valve I do which is not near as bad as the original valve mine shipped with. If it jumps an inch I'd not let go of the dealer until it was resolved.
