L2800 Position Control (Jerky?)

[Toy Camry]

Came across this interesting tidbit of advice on the Kubota Tractor USA "Kubota Ten Commandments of Tractor Safety" web page.

" Practice smooth, even transfer of loads. Sudden, jerky movements are dangerous and can damage equipment. "

In Kubota's own words "Sudden, jerky movements" much like the way our 3 point hitches operate !

Not only is it very difficult using our position control valve to accurately position our lift arms I am also concerned that the violent jerking is not particularly good (or safe) for our tractors or the implements that we put on them.

The above quote can be found at the following link.

Kubota Tractor USA - Ten Commandments

Although it is under the Backhoe Safety section I am confident that this bit of Kubota Safety advice applies to general operation of the Tractor as well.

Safety / liability issues can often get priority when it comes to management...just a thought.

In post #43 of this thread, I posted the pages from the parts manual for the 3ph valve. One page is titled "Old Valve" and has two different part numbers with serial numbers. The other page is titled "New Valve" and shows still a different part number. Can anyone cross reference these numbers to the L3010.

Terry, I cross referenced the numbers posted in #59 of this thread with parts books for the L3010 and L3400 I found on the web. This information should be accurate but I can't prove John Deere didn't put it out there in some brand war conspiracy.

Toy, VERY GOOD POINT.

Good research. I must have missed that post. The pages I have from the parts manual are close to what you have with the serial numbers being a little different, but I don't think that makes any difference in this case.

Not sure why the serial numbers differ but I remember reading a post that listed different serial numbers for the L2800. My reference indicates the L3400 DT/HST.

Have you had any more luck with part numbers to fix our problem?

 

[Harvest Moon]

No luck here, don't really expect to dig into it till I'm either really board or really frustrated. All my good tractoring projects are on hold for indoor work right now... Funny, I hate being inside when the weather is nice, don't mind too much being outside when the weather is bad.

Still hoping for a missing piece of the puzzle as I see it, it would be of great help if any L3010 owners reading could take a minute and respond to my L3010 owners question post.

Go outside and raise your 3ph. If your like me you will be really frustrated. I'm still working on Kubota to help us. You know the saying, "there is strength in numbers." I think we need to here from more frustrated 2800 and 3400 owners. I hear a lot of people say it's not good but I can deal with it. Not me!

I'm kinda thinking we're going to need to help ourselves on this one. I'm fairly sure if I want my valve changed I'm going to need $400, my WSM and about 8 hours (learning curve). I'm over 170 hours now and can't imagine Kubota fixing my tractor with the fight they've given others with brand new tractors. And I'm not too impressed with their latest upgrade work anyway.

A quick scan (rough count) of this thread and 7 people had the valve replaced and seem fairly content with it, two had it replaced and are still unhappy and two, me included, didn't get it replaced but would like to. I'm one of four currently unhappy posters and there are many thousands of these tractors out there.

That said, if you're reading this and you have one of these tractors and you're not happy, speak up and be counted!

At this point I'm just trying to figure out what the best option is, I'm not too interested in Kubotas option because I think they don't want my tractor to work well. Of course, if during my travels I come up with a better solution, I'll let everyone know.. unfortunately I might have to post it in another color.

OK I'll be counted.I've had my 2800 for just under four years and 170 hours. It will jerk my heavy duty Squealer all over the trails I cut. But the real nightmare was when I needed to use a borrowed augur to drill a few post holes. I gave up on the first one worried I was going to tear it up the jerking was so violent. If the implement doesn't weigh several hundred pounds I can't use it. I did mention the problem at the dealer just to see if they had heard of the defect. This was three years ago while they were performing some very questionable warranty work and I didn't want to push it. But they claimed they didn't know of any problem. At that time some people had said their dealer had replaced their valve for free.

My 3400 is brand new (10 hrs.) and I'm totally happy with it. I have bladed, box bladed, rotilled, and done loader work. The 3-point raises in 1/8 to 1/4 in. increments and I really like it for box blading. I can make it shake violently if I raise the lever very slowly ( which catches each increment on the lift), but if I just raise it, it comes up smooth. My JD4300 had a smooth lift, but I always had a hard time getting the box blade at the right place. I hope you guys can get your problems resoved. There's nothing worse than spending hard-earned money on a machine that isn't right, and a dealer that won't help. (I know that from my JD4300 experience).
