3-Point Hitch L-series Jerky 3PH - Jeff's homebrew repair.

[Notforhire]

BTW it is a common problem, IMHO.

I would have them call you when the tractor is repaired, and test it at the dealership before they deliver it to your site. The next delivery, (if needed) may not be free.

There is lots of info on this forum discussing that hitch problem. I would suggest you read up, then you will know what to expect. Good luck.

Best, Bill

Here is typical operation if the 3pt lever is operated slowly

here is one that has been "fixed" But the owner does not have a clue what the dealer really did to fix it. He was told by the dealer that they ordered a replacement valve and adjusted it properly.l
The question is VALVE OFF OF WHAT? WHAT IS THE PART NUMBER OF THE VALVE. HOW WAS IT "ADJUSTED" you just want to scream these questions, and there are no answers.

The thing to look out for on a "band aid fix" is raise the Front End Loader and watch the 3pt to see if it drops then returns to position after you let off of the FEL joystick.

Great advice from all on this matter. I like the "call me and I'll come to test it", and watch the operation of the fel when the 3 pt. is raised. I paid Lots of $$ for this machine and I want it right. I may want to sell in the future to upgrade and the last thing I need is for a potential buyer to say it's defective. Which it is!

I bet you would be happy if yours operated like the one the is fixed in the second video. I would have been too, mine was so bad with a heavy ballast on the back and you operated the lever slowly, it would darn near jerk the rear wheels off of the ground. Or so it seemed.

I watched the video. smooth, that's what I want.
My 3pt. is jerky even without weight on it. When I test it at the dealer, should I test with an implement?

Yes, the problem is worse with an implement on the back. boom pole would be ideal, but box blade or scrape blade or mower will show it too. You cannot see much with just the bare lower lift links.

Before i start, this is entirely my experience, so I can't speak for everybody. I bought a L3200 and about 2 weeks after operating i noticed the jerky hitch. The only reason i noticed was from using my dad's Grand L up until i bought mine. I researched here on TBN and found out all about the highly popular "jerky hitch". I then called up my dealer about the issue and he told me to bring it down and they would take a look at it. After talking to the sales manager he explained alot to me regarding the issue and set alot of truth straight from I've read on here and other websites. Alot of info i gathered online was true and alot wasn't as I would learn. I left the tractor and 3 days later i received the call to pick it up. Boy was i surprised. Not a single quirk in the hitch. I tried everything from high rpms's small increments on the adjusting,ect. Perfect! I asked what had been done , his reply back was "some small adjustments to the valve assemly". I asked if it would affect the weight capacity of the lift and he replied "no". After returning home and some 2 years later everything he said was true. So when i decided to upgrade and buy a FEL i came back online and discovered the issue at hand of the fel and jerky hitch. It seemed at that time those who could fix the jerky hitch had problems with the FEL. So yet again after talking to the salesmanger, he told me to bring the tractor and don't worry about nothing. He even told me that if i had a issue he would take off the fel and not charge anything for the install. So with that said i had the FEL installed and much to my surprise not a single issue. He also told me that ever since my inital incident that every tractor on his lot gets the valve adjustment before leaving,and i was told that comes straight from Kubota. However i don't understand why Kubota can't fix the dang issue at the factory rather than leaving it up to the dealers...Which is where i think the second inital problem comes from, getting somebody willing to fix it and working on it till it's fixed. With that said don't believe everything you are told. My experiences only.

Worth repeating. Looks like it Can be adjusted... You have a good dealer!

This may or may not be related, but lately I've been having problems with people who deny what they say.
I've talked to salesmen on the phone and when confronted in person I hear "I never said that, or You misinterpreted me"
This is frustrating. I hate to confront people and say Yeah, but put it in writting, maybe I ought to carry a tape recorder.
