Howdy from East Texas

timberland · Jan 19, 2012

New guy here just checking in. Lot of great info here.

Well i made a recent purchase. Kubota L3400, 4wd, ag tires, 150hrs. with FEL.
Tractor serial # 57809.

Question; does the 3pt lift valve need to be upgraded, if so does anybody know the part #. Jerky lift syndrome - I have already purchased the return hose, not installed yet though.

Thanks

The valve can be adjusted at the dealer. My dealer here in Splendora (East Texas) just adjusted mine (L3800) and it's perfect.

You got yourself a great tractor.

Welcome aboard!

I don't have an answer for your question, but we're always glad to have another Texan join us.

And yep, that's a nice tractor you've got.

The earlier L3400's used a different valve. According to what I have found, a serial number greater than 55652 and less than 61731 will have valve number YR909-00100 or 31351-39604 which includes your tractor, if it hasn't already been changed.

The latest valve for the L3400, to the best of my knowledge, is part number YR908-00104, which is in SN 85656 and higher. The L3800 uses a different part number, I think.

A dealer that's familiar with the Kubota parts book should be able to tell you what will work the best in your tractor, as well as contact Kubota for compatibility. The latest valve will help somewhat, but I believe fine tuning and careful set-up is the key to making it truly smooth.

Mine has a newer type valve, but it's far from smooth.

Changing the suction hose may help, it made no difference at all to mine.

Good luck and enjoy the tractor!

Howdy...did I say that right for a northerner??!!:laughing:

Can't help on the valve, but welcome to the forum, lots of really nice TBN members from Texas.:thumbsup:

Welcome to TBN! I have learned eveything I know about tractoring (?) from TBN and lots of seat time on my L3430.

Welcome.

I purchased a used L3400 this past spring. It has loaded R4 tires, FEL, and back hoe. Seems like a nice tractor, I had a L2950 with FEL I traded in on it. I have the jerky hitch syndrome also. Nothing I really can't live with, but would be nice if it was smoother. I have been removing some trees and it seems to do the job fairly well.

Are you near Tyler? Rose County Tractor has been very good helpful when I have a question for them. Either Rose at the parts counter, or any of the guys in the shop will stop what they are doing and answer your questions.

OK, I gotta try this out.....

Howdy pardner! How y'all doin'??

How'd I do?

teg · Jan 21, 2012

...I forgot to answer your question. Since it seems like it's a used tractor:

The cheapest route to take is to learn to live with it. *IF* it's sooo bad that you can't live with it... it's gonna cost you if you can find someone to work on it.

I would talk to a dealer that has already "adjusted" them before and see what it would cost OR see how much it cost to have the valve upgraded. The valve *was* $430 a few years ago. Most of the cost would be the labor.

From what I've heard, it's not a do it yourself job.

Welcome to TBN...

Longview area.

been using a 9inch auger this weekend, did about 20 holes so far. sure would be nice to have smooth lift on the 3 pt.

Have a 5 foot box blade have not tried it out though, anybody tried " Jeff's homebrew repair "

I would be very interested in adding the adjustable flow control gizmo.

Or upgrading the lift valve...

teg · Jan 21, 2012

Funny, the only time I liked my jerky hitch was with the PHD, it would fling the dirt off very well...

If I remember correctly, " Jeff's homebrew repair " wasn't that cheap. Have you talked to a dealer to see if it could be adjusted? $$$
