3 point moves up and down with loader

You may want to talk to them about installing a Grand L valve in your 3PH.
I almost bought a 3400, but the jerky hitch killed the deal. My dealer was going to install a GL valve as a fix for around $400. From what I understand Kubota won't pay the dealer for the conversion, so they are on their own.
Good luck.

Is the grand L valve a direct fit or does it require some mods

 

[Notforhire]

Is the grand L valve a direct fit? I don't really know.
All they were going to charge me for, was the valve, so I expect that it was a direct replacement.
The same dealership had done a GL valve for another TBN member"s L3200. The only reason I knew anything about it was from this forum. Dealers are very closed mouth about the whole deal. They told me that the other TBN guy and I were the only two people that had a problem with the jerky hitch. Baloney!
Because I had not acccepted delivery of the tractor yet, I decided to go with a leftover 2011 L3240 they had, rather than convert the valve.

James is right. Mine has almost 300 hours now, and is solid as a rock. A jerky rock when you're trying to raise it slowly, but solid otherwise. It only dropped and raised when I adjusted the valve to the service manual specs, and they don't come that way from the factory.


Sean

If they want to try and fix the jerky raise (I assume yours does this), they maybe should read the thread on adjusting mine, and be aware that there might be side effects to simply adjusting the valve to the specs in the service manual.

If it does the same thing mine did, I doubt you'll be happy with it, unless they're willing to put it back as they found it. It is the lesser of two evils in my opinion.

Sean

Same here. Solid as a rock now, only jerky when raising slow. Other side-effects were only from me tampering with it trying to make it better

Well, thanks again.
As it happened today the dealer (I think it's the same as Sean's) came by my place to drop off some stuff. I mentioned to him the problem with the jerky 3PH. He did not exactly deny the fact but also did not see it as a problem (he acknowledged though that there were problems on the L3400s).

The only concern I have at the moment is when going out to scrape and grade the private roads in our development (we have to maintain the roads ourselves, dept. of transportation does not do it) with a scrape blade or box blade attached. From another essay in this forum (Beginners guide to using a box blade) I understand that one has to (almost) constantly adjust the BB a little (maybe I misread though). This would give me pause of course as a minor up adjustment is not possible with the 'jerky' 3PH.

Does anyone have any experience with the use of a BB on a so called 'jerky' hitch.
Thank you.

Yes, that was my problem, minor adjustments to use the box blade correctly. You need to be able to do that to use a box blade correctly. Period.

The other issue of lifting 600 lbs out of a trailer on a 6' boom pole was NOT fun with the old valve. The new valve out of a Grand L that I got is how it should have been from the get-go. (and yes I would have paid more for it).

The tractor industry has had smooth valves forever... IMO, I think they "added" this feature to separate the two models. That is only an opinion.

They want me to day the differnece from the standard valve to the Grand L valve

wonder how much that will cost

 

[teg]

long time ago, it was $430-ish

Thanks, Dan. Just what I was thinking.
I am almost tempted to go for Rogerius' "THE Kubota fix" and upgrade to an L3240 :licking:.

And what's the standard valve cost

And what's the standard valve cost

Oops, that is the Standard valve cost several years ago.

Ok, I just looked up the valve I THINK was used in my tractor (not going to list it since I'm not 100% sure - you have to do your own reading or get your dealer to look up the original "Product Improvement Bulletin" - most of this was posted several years ago.)

And Yes the non-jerky valve is definitely more expensive - $476.42 vs. $474.61

Also, The PIB was only to be used in the original really jerky models.
