Interesting phone call from Kubota the other day.

I don't know what design that kubota uses for a valve.. butI know there can be at least 2 different designs. On one design, the valve is rigid.. opening it a little will decrease oil flow in, and out.

Ont he other design, there is a spring loaded portion that allows oil in dramatically better.. while still blocking oil out. There was a thread in the chinese tractor section converning drop valves and i believe somebody posted pics that explain a lot better than i just did on how this works... I'll see if i can find it.. etc.

I'm no expert on hydraulics but on both the old valve and the new valve, downward movement was a heck of a lot smoother than upward movement of the 3PT.

That said, while adjusting the fall speed knob did appear to have some effect, the original valve was way too jerky for me to consider normal.

Mahana - chances are you already have the upgraded valve. Even on the new valve, I do see that you can get it to be slightly smoother by playing wiht the knob.

I e-mailed Kubota customer service last nite, web page states to wait at least 1 week for a reply.
Now I know why they call it the "L" series --- it leaps up!!

Thanks for the we come,although I 'm not new to TBN, had computer problems about a year & a half ago, which for some reason caused by password to stop working after trying to get someone at TBN to answer my numerous request during that period I decided that there was no human actually at TBN so I reregistered.

Now to answer your question the numbers are the same for DT and HST, the two wheel drives have a different set of numbers.

What exactly is this valve that is causing all the problems?? I have operated tractors for years, but don't know a lot about hydraulics, etc. I had the very bad jerkiness on my L3400 and my dealer replaced what they called the cushion valve inside the rear housing at the top of the housing about a month ago. It works great now and is very smooth?? Is this cushion valve the same as a control valve??

I am looking forward to finding a Kubota rep that will put a Kubota post hole digger on my L 3400 and take the time to operate it. Reps are supposed to support both dealer and customer, why can't the customer find the rep???

Yawn... for real now. I think I've read about 4 threads this morning and they all talk about lawsuits. Somthing is really wrong with people.

Ah yes, since I am named in six lawsuits right now, with two being directed straight at me, I can understand your point. Funny part is, is how it is going to turn out in the end. More later, but I can understand your point. I may have to enter at least two more before this is all done. Not looking forward to it, but life goes on. My signature says it all.
