whats close to a L-2800?

[number two]

What about a B2630?Premium tractor with position control,silky smooth 3 cylinder engine,almost a B3030 but less money.B2630 or B3030 will handle a 5 foot box blade and 6 foot rear blade very well.Both use the LA403 loader and ATI makes a quick atach for the bucket and forks.Good Luck!

[quote=Chilly807;2436891]This reminds me of the movie "Groundhog Day" with Bill Murray, where he keeps reliving the same day over and over.. this thing just keeps coming back, like a cat.

Much as I'd like to see this issue solved, you have the easiest option of all.

Take Kubota up on their offer of a refund, and be done with them. Deere, New Holland and others make good tractors without this frustrating problem. They didn't get to be the size they are by building inferior machinery. I'm brand loyal to Kubota in most things, but the 3-point thing isn't one of them.

If they've exhausted all the avenues they're willing to go down, then anything you try may void your warranty.

Mine is jumpy too (2009 L3400), but not bad enough that it overshadows everything else the tractor does so well. I've got a few ideas about how to fix it, but I'll wait until the warranty is over before I try it. And I'll have to have time on my hands, and nothing better to do, so this may take a while...

Good luck, let us know what you decide to do.

Hey Sean, you do know if you really come up with a way to fix this with lets say less than $200 bucks, and 4 hours of time. You could sell this as a kit, and make yourself some real money. It's all on your shoulders now Sean. No pressure...

Pressure.. hmm??

I have a 09 L2800 and it seemed like my 3 pt jerkiness got better after a couple hundred hours. It still does it if I keep moving the lever up slow in little bits but I just pull it to about where I want it quickly and it goes up nice n smooth. At first it jerked at least once everytime I lifted it now it hardly ever does.

I was disappointed at first by the performance but as it is 300 miles to the road by boat and then another couple hundred once I get to the road to the nearest dealer I figured I would just live with it. Glad it fixed itself or maybe trained me not to notice

Number two.......thanks for the input, actually all of you, thank you for your input. Number two, I have an appointment on Wednesday with a man who lives about 20 minutes away from me. He has a B2630 and uses it almost exclusively like I will, to maintain a driveway. His driveway is hilly and I am told by my dealer who gave me his number, that the B2630 works wonderfully for him. The man is going to show me how it all works on his driveway. I'm keeping my fingers crossed.

I looked at a Kioti CK20 today. I wasn't quite as impressed as I am with the Kubota B 2630/3030. I haven't sat down with the literature and compared specs yet. I am thinking that the Kioti will beat out the Kubota on things like FEL lifting, bucket height and so forth. I may still go with the Kubota though. I'll just have to see how things work out.

I forgot to mention that yesterday my dealer hooked up a 6' heavy box scraper up to a B3030. Using the position control lever, it was silky smooth going up and down. Amazing, thats how they should all be. I was quite impressed with the 3030. I understand the 2630 is the exact same tractor, except for the engine and horse power, the 3030 having the 4 cylinder 30 hp, and the 2630 having the 3 cylinder 26 hp. We'll see how things work out tomorrow.

kubota dealers should be required to do the same thing to everyone buying an L2800-L3800 tractor. Then have the buyer sign a waiver saying they are fine with it... :2cents:

Now that would be admitting there IS a problem, right??

Dumb question but.... If this is a flow issue idling the tractor down should make a significant difference Vs running 1/2 to 3/4 throttle. Just out of curiosity has anyone tried this? Not a solution but might point towards a possible cause and or potential solution.

I know on my little BX the faster the engine speed the quicker the lift so i would presume similar results with an "L" series but I have driven one so don't know for sure.

Even at idle it's rough, worse at higher RPM. You learn to live with it, at least I have. I'll say this much, if I ever buy another tractor I'll be checking the 3 point first. Probably I'll miss something else in the process

My solution (to be done shortly after Hel freezes over at this rate) will be to modify the lowering adjust valve so that it restricts the flow going past it in both directions. They are currently set up like a check valve, allowing full flow in one direction (raise) and metering it in the other (lower). Simply removing the check spring function isn't the answer, it almost has to be a separate circuit.

It's complicated enough that Kubota has shied away from it, obviously. If it were a simple fix it'd be done whenever an owner complained about it. Poor design on an otherwise really good tractor.

They are on the youtube link above, under my name... not with the spray rig but others. Just as jerky... almost as if they went out of their way to make it that way... sorry my conspiracy theory pops out every once and a while...

EDIT... actually the description I have isn't worth a hoot, if you play the ones like this, I tell you on the video high or low RPM and the adjustment of the seat knob... there a few like this. This is without a load on a boom pole... wish I had a bucket of water on the end of it.

I hope you make out well witht he B2630. I don't understand why everone has to the B3030, but we are like that in this country I guess.

By the way, you should check out a Kioti CK 25, or CK 30 if you want something that compares to the L-2800.
The CK 20 is quite a bit smaller though almost as heavy.

Glad you mentioned that, Chuck. About the only time that power requirements are a priority over weight/traction is if you're using a PTO driven implement.

My L3400 runs out of traction even with R1's long before the engine is overloaded doing 90% of the work I use it for. About the only time the engine has any amount of load is using the rotary cutter, and I've never had enough load on that to bog the engine down. I could use more weight though..

Chilly & Teg, thanks for the info. Yes it sounds like Bota dropped the ball on this similar to the jerky stop on the 50 series BX.

good luck on finding a solution

Chilly & Teg, ...good luck on finding a solution Roy

Roy the solution is replace the valve (not sure if it can only be done to the early models, 2004-5) but here's a crappy video of the "after" valve replacement... (sorry about the sun and bad camera angle :ashamed

I've got the same problem with my L3700su. I'd love to have something that works as good as Teg's video. Its a 2010 model purchased last thanksgiving.

I've been to the dealer about this. I showed him the jerky hitch, he said it shouldn't do that. He had his service department look at it only to be told they called the regional rep, and they said it is normal for this tractor and nothing can be done or upgraded. Was given the line that this was the economy tractor and this is what you get. Dealer said this is the first he has heard of the jerky hitch. I've considered trading for a different model, but really the L-series is the best fit for me. I'd like to just fix the valve. This is so stupid, it should just work!

Let us know what route you end up going. The b-series will probably work well for you.

 

[unfinished]

I just had to run out and make a quick video of mine. Don't know if it compares with the early ones but its pretty bad. Its fine if you just need up or down, but trying to be smooth with a post hole digger is impossible. Love the tractor otherwise.

I use a chipper that takes a 4" X 6" maximum size piece of wood, and have had no issues whith power. I have 26 HP from the engine, and 20, or so on the pto. If I were going to trade, I would look for something no larger than your L, and weight, the size, and capabilities for a backhoe, etc. would be more important to me. For all around use on my small 13 acres, I like the light weight of the B most of the time, and I have the same clearance under the tractor as an L. I have used the Kubota B series with the 4 cylinder engine, and have been bothered by the vibration on one of them at least. I've been working on trails in my woods........ well, acutally reclaiming some old, and very deeply rutted skidder trails, and there have been times when more weight would have been nice, but the only time I've wished for more HP was once when I was snowblowing some deep, and wet snow. The 54" snowblower actually strains my engine more at times than the chipper does, and there are places I go now with my B where an L just woudn't fit, and I would have to improve thee road before I could go there. (Think between glacial rocks that don't move much) , and there are a couple of places that a wider loader just wouldn't fit between the trees, and they are "boundry trees" so can't be cut. ( I am planning a different route for that issue, and it would only have to be something like 40' long.) With the rocks, I usually build up the trail with small (3" - 4") rocks, and cover that with gravel to gain the width I really need though it sure is nice to be able to slip between those places in the time being. The land in my woods is that black glacial soil covering a rock field. It just gets more soupy each time you drive over it when it is wet at all. It is however a wonderful playground, and I don't have to use those trails right after a rain, etc.

Sorry, I get carried away when i start talking about my land sometimes. Anyway, the size you want, and the options you want, or need are more important than HP. I should add that if it doesn't make you smile a bit when trying it out, you don't want it. , and make sure you choose the size, and type of implements you want to use first. You already have yours so that part is already decided. It is a real joy to putter on my land with implements that work, and a tractor that makes me smile.

That's pretty bad... good video (quality-wise, too) :thumbsup: That must be pretty tough without a suspension seat

Something I forgot about.

The original valve that was just lousy, so much like the one in unfinished's video. Then there was the upgraded valve and everything was so much better. The one that made teg's day.

When I went through the hoops to get mine upgraded, I was offered the newest, latest and greatest valve with a promise it was the best out there. And I couldn't have said NO fast enough or loud enough. I insisted on the first upgraded valve because at the same time I was upgrading, L3400 complaints started to come in about 1"+ jerkiness.

I think Kubota changed the valve, back or forward, away from the one that teg and I have. I've always suspected the jerky valve was an up sell strategy and that they never intended for it to work smoothly. The valve teg and I have among a few others on TBN, may be a little tooo smooth for them. Something to look into, what is the part number on this latest problem valve?
