If only someone from the Kubota design team would come on here and tell the truth, what ever it is.. We would all feel better. Sean what is your hat size? I can whip up a shiny new hat pretty quick

I wonder what Teg's valve was to begin with?? was his the pre-617xx serial# valve like mine.

If they "did" install a 3010 valve, that is the valve that was used in the L3400 between 61xxx and 69xxx like you said. And if that "did" work, why change again???

I know its a narrow range (only 8000 exist) but it would be nice to hear from someone else in that serial # range and find out what their hitches are like. Not sure, but guessing based on when I bought mine and my serial #, that range would have had to have been sold as model year 2006's?????? and maybe early 07's. We hear of soo many people on here with the jerky hitch, but with so many different valves used, maybe the only ones complaining are the ones with the early valves like mine, and all the ones after they quit using the 3010 valve. Maybe the 3010 valve does indeed work:confused2:

But then again, why does the valve I have work flawlessly in the 2500, 2600, 3000, and 4400????????????

Oh no you don't... there's no way I'm painting a target on my back... it'd be like a lynch mob, complete with flaming torches and pitchforks...:laughing:

There's probably a picture in the Kubota factory in Japan, with a likeness of the poor SOB that designed this thing hanging in effigy as a warning to their current engineers. :shocked:

Or (if you subscribe to the conspiracy theory) he has a nice plaque on the wall citing him for engineer of the year.

But its not like the valves they have been using are unique to ONLY the L3400 series. But yet the 3400 series is the ONLY one with issues:confused2:

The 3400 series is not the only one with the problem!

I tested FIVE brand new tractors, two L3800s, a L4400, a L4600, and a L3240.
The only one WITHOUT a jerky hitch, was the L3240.

I suspect, that had I tried a MX4700 it would be jerky too.

I have been reading for along time about this and the only thing that keeps popping up in my mind is the hyd system isn't matched right. Meaning the flow rate isn't right from start to finsh. That could be pump,lines,fittings, and the 2 valves if there is a loader on. Does this make any sense?

I have an L 3400 that I purchased in January of this year. It is serial #69369. It has a back hoe on it but I did purchase a used snow blower in late March. Never had a chance to use it but did connect the blower to test the PTO and Hydraulic shout. I too have a Jerky Hitch. I'm kind if bummed about it since I want to purchase a box blade in the future to do some road work. It's my first tractor and so far I'm amazed at what it can do. The back hoe is so useful. It is used at the cottage just west of Algonquin Park in Ontario's cottage country. I've been making the trails in the bush for maple sap collection smoother and getting rid of a bunch of rocks in the driveway and parking area as well as putting in another driveway enterance. Amazing machines. I have been following the threads about this issue for some time and until I use an implement that requires the finesse in raising the 3ph I guess I'll just keep following the threads. I still shake my head over how a company that builds a great product with the reputation for reliability can let this happen and go on for so long. In this day and age of electronic forums, it has already cost them customers. If I was a dealer trying to appease a customer I would be furious. I enjoy reading the comments here. Keep them coming.

I suspect there's more than one that have pulled out some hair over Kubota's attitude toward this. As far as I know, there has been no warranty support for any of these adjustments, fixes, repairs, call it what you like. Those that have been covered are probably "fudged" under the valve being defective, sticking, whatever.

I've heard that they're one of the more difficult makers to deal with when it comes to dealer support, in one gentleman's words,"It's like they're doing you a favour every time you call them".

You're right, the internet is NOT their friend, in one sense. We all have access to the poor 3-point hitch performance saga, but we also have access to the rest of the tractor experience with the L series, which is by and large very good to excellent. It's a great product with a drawback, and they're still selling them, so really from a corporate point of view there IS no problem.

Wow, :shocked: You guys have been busy!!! ...and why are you guys calling it a "theory" :laughing:

First off, mine is the L2800 (54xxx serial number) I never got a confirmation what the dealer really did but it's very smooth. There was a little talk, which I don't believe, that mention a change in the casting that prevented the use of the Grand L valve anymore... anyone believe the casting changed? :confused2:

Also, I heard but can not confirm that another tractor was recently fixed up like mine. The gentleman is not that far away from me and invited me over to check it out... I never did but I might re-think that.

When some of you guys were opening and playing with your valve settings... I got real tempted to look into mine. I'm putting that off until I have to replace the crappy CAMS. More I use my tiller, the closer I am to that point.

Shoot this jerky stuff has gone on waaaay to long... I've grown tired of it (several times ). Recently, talked my friend out of an L3800 which he had priced out...
