L2800 3 point shudder problem

[k7oi]

I have L2800 HST, and had the shudder "fix" done 6-4-2006, just before the warranty expired
It seems quite a bit better, but I'll admit I haven't tried the post hole digger yet, which was the absolute worst as far as the shudder went. I got a new back hoe at the same time, so I've been playing with it!
Good luck! Terry

Just curious, the L4400 is from this same family of tractors, does it require the fix also?

To all, I spoke with a Kubota rep in Suwanee GA regarding my 3-point shudder problem. At first he told me that the L2800 is an economy tractor and that I am not going to get the smooth 3-point action of my M7040. when I said I wish someone would have told me before I spent good money on my tractor and that I could have paid the same price for a NH TC-30 with a properly working 3-point, he back off a little. Here's his recommendation, sit on the tractor at idle speed, with an implement attatched, raise all the way up. Again, while on the seat, turn the speed adjustment knob all the way to the left (towards your left leg). Turn it so tight that when you try to lower the 3-point, it will not do so. Back off the knob turning ever so slighlty to the right and the problem should subside. I am going to try it tonight when I head to the farm. Will advise.

Hate to say it, but the only thing thats going to cure your shudder, is a new valve. Don't let up, Kubota should do this for you.

Alright guys, I followed the Kubota techs advice and it's a lot better. I realized that the threads on my speed adjustment knob was rusted tight. Once I got the knob to break free of rust, I raised the implement all the way up and turned the knob as hard left as possible so that when I tried to lower the implement, it would stay up. I backed off the knob intil the mower started to lower at a slow rate. Reved the engine to 2k rpm and there was still a slight shudder when I raised the mower, but a lot less noticable. I can say that I can live with out a silky smooth 3-point. I did have better results when I would just pull the lever up at a quicker rate rather than really slowly. Try this and I think you will be happy. It's a lot better than having the back end of your tractor in pieces in order to replace the valve.
Just a thought.

"It's alot better than having the back end of your tractor in pieces in order to replace the valve"

I may be wrong, but I believe you would think different if you could try one thats had the valve change done on it and see the difference. I couldn't believe the difference when I got my tractor back, and I'm sure others will agree with this thats had the change done in their tractors, but if your happy and can live with it, then thats what really matters.

I thought that adjustment knob that you are talking about only was for adjusting the speed that your implement lowered. I never could see a difference when raising my three point hitch after adjusting it, just a difference when lowering.

If you ever want to use a rear blade, box blade, rake, etc. You will get very frustrated trying to make a small adjustment. It will jump an inch or more. Totally unacceptable for that kind of work. I'd just get it done.

Whichever idiot at Kubota came up with this 'Economy tractor' line needs to learn a thing or two about customer service. You don't tell people that have spent $20k for equipment - "oh ... you just bought the economy model. If only you handn't been so cheap and had sprung for our deluxe model".

No where in the brochure does it say that L3400 valve is not smooth as the Grand L valves - like it does for say the B7800 (1/4 inching valve) vs. B3030.

I would beat on Kubota to get the new valve. World of a difference.

I agree! Not having a smooth 3PH is Ludicrous.

Do these engineers actually ever drive a tractor and do any work with it???

 

[Goog]

Get the valve. You won't regret it. As stated before the knob is only for adjusting the lowering speed. It is night and day between the two valves. You also might consider that someday you may want to use an implement where it is critical to make a fine adjustment upwards and without that valve you will not be able to. Brian

If Kubota had clearly said something about the valve (as they do with the B7800) in the product descriptions then I think that they *may* have a leg to stand on here wrt. Economy vs. Grand L.

I say *may* because a 1 inching valve is pretty darn crappy anyway and it shocks me everytime they give someone a hassle about this.

 

[crbr]

In my opinion, the 1/4" valving is just as crappy.

Agreed... at least they tell you that upfront so that the buyer can consider that as a difference between the B7800 and B3030.

Got a response from Kubota , they said Dealer would contact me .
See how long it takes !

Got mine fixed with no questions asked. There is a service bulletin that addresses this exact issue word for word. All the service man needs to do is pull it up on his computer. If they won't honor it, I would go to another dealer.

If you haven't seen it already here is a whole thread on the problem.

Took my L2800 in today and showed the Kubota tech how voilently my 3-point shook when I raise the mower. He asked me if I bought it from them or somewhere else. Told him from another dealer an hour away. Then the SOB started bashing my tractor saying that it was the worst thing Kubota ever made. I got really angry with this dude. I told him that if its so bad why is there one in the showroom and why is his so **** overpriced compared to the rest of their competitors. I told him that my family's farm has done a lot of business with the dealership he works for and that he has jeopardized any future dealings with them. I shut him up and said that he would fix it. He was a cocky little guy that spoke very poor english. I believe he was a direct service tech employed by Kubota. Not sure but I am anxious to get it fixed and then cut all ties with this arrogant dealership. By the way, we have bought a Kubota M7040, JD 757, Mill Creek spreaders, Sthil weedeaters, blowers, a Gator....all from this dealer. I'm thru with them after this. Too bad the other bota dealer is 70 miles away.

 

[canoetrpr]

Bama. I understand the irritation but did you get to the bottom of why he though that the L2800 was the worst thing Kubota made?

Was there actually some valid point that he was trying to bring up? Did he have a lot of experience with these tractors.

The PTO issue has gotten a few of us nervous particularly since official reps from Kubota keep calling it an 'economy tractor'. What else has been 'economised' on?

There are LOTS of these tractors - L2800/L3400 - being sold and other than the valve issue I don't think there have been reports of widespread problems.

 

[bama85]

No, I never got a defininte answer as to why he thought/said that about my L2800. I believe that he was pulling my chain a bit but he did set me off after that comment. He could have just been having one of those days, even though it's unacceptable to say that to a customer. He was Japanese and his English was very broken. He also asked me if I have had any problems with my PTO. Told him no and asked him why? He said that he had a customer tear up two pto's from a tiller on both an L2800 and then his L3400. I told him that the PTO works great and powers my 72" finish mower just fine. When I lef the dealership, I really did feel a little defeated. The bottom line is that this machine is and has been great!! I love it and wouldn't trade it for any other tractor in its class. It has plenty of power, beefy front axle and plenty of gusto to do anything that I can throw at it. The 3-point problem is minor and will be fixed. I really don't mean to turn anyone away from any Kubota products because I believe that they are the best machines in their respective classes. I just am ticked about the pissy remarks that this guy made at the dealership. I am going to file a complaint about him after I get my tractor back.

I had my PTO to fail twice on my L2800 from using a roto tiller, but it didn't come from your dealer. You think it may have been me he was talking about. That's interesting, as I was told by Kubota that I was the only one who have had problems with the PTO on this series of tractors, other than complaints about the noise they make.
We are not all that far from each other. My dealer is in Southern Indiana.
