Jerky Hitch Fixed!

[kubotacres]

Well I got my tractor back today with a smooth operational 3 pt hitch. No more jerkyness when lifting items and when grading. It took a little help from my dealer and a call to Kubota Corp but it all worked out. My jerk was sloppy as heck and hopped the front of my tractor off the ground on several occasions. I tried my best to make it do something today and it's a smooth as butter. Also the work was performed under warranty and no cost to me. I can't wait to start finishing my barn now! :thumbsup:

You need to go buy a lottery ticket as you are one of the "few, yea lucky few, yea band of brothers".. Most of us cannot get our dealers or regional reps to do anything about it.

Great news. That's the way it should be. My dealer did the same back in 2005. This seems to indicate the problem may be more with dealers than Kubota.

....so what did the dealer say was the problem?

I see you don't have a FEL in your Avatar... So a jerky hitch would be more noticeable!!! I would also love to know what your dealer was able to do to fix it... Was it just adjusting the valve or was it replaced? (and with which model?)

Congrats, and welcome to the club

I just bought a new Front Grill Guard with weights to actually help with the front-end being light. But there shouldn't be any problems like before with the hitch not hopping like a jackrabbit.

As for the fix, no replacement was made, just adjustments. However I'm still unclear as to the specific fix. It shows that two parts were submitted under warranty.

Assy Valve Control Part# YR908-00105
O Ring Part# 04817-00120

Then it reads that the control valve was removed and adjusted to spec in manual. So I'm assuming the valve may have been replaced and then adjusted. Either way the adjustments they made fixed the problem. Actually about to go start lifting some railroad ties now to test it out...

And yes i believe the Dealer is probably 75% the reason for getting my tractor fixed.

The fix is interesting. I will say this. When I installed a rear remote and connected a cylinder to it, the 3PH was jerky as all get out. I just had a 6' rear blade on the tractor and a loader on the front and it made the tractor bounce a fair amount.

I topped the SUDT fluid off to make up for what went to fill the new hoses and cylinder, and operated the hitch a few more times and it's back to being smooth as can be. I wonder if my experience has any relationship to the jerky hitches that have been reported on here. ....maybe air in the system, or the 3PH is extremely sensitive to the level of SUDT?

If this is on your Kubota B3030... it's not the same thing.

I would bet it's more like 95% the reason. MOST dealership mechanics are quite incompetent at doing anything other than routine work or reading something out of the book. From my research on it it's not a very cut and dry fix. Glad you found one that was able to diagnose and fix the problem. :thumbsup:

The repair is an adjustment to the control valve under the 3 point hitch cover. Apperantly they are mis adjusted. Anyway, any dealer can do it. If they do not know how, they can call the Kubota Tech line and get help. This applys to L3200 and L3800s only. It is my understanding that they do not have serial number breaks on which ones were incorrectly adjusted. Correction to my previous note, the L2800/3400/4400/3200/3800 (at least the late production of the L2800/3400) all have the same valve on them. It is my understanding (from customers and TBN users) that when this valve is adjusted correctly, it operates well with in customer expectations. Please note that the early L2800 and L3400 did have a differant valve that did not have the same operating charactoristics as the "better" valves. Sorry for the confusion, TEG got me straight on this.

As a side note for other threads, there is no "other" or "better" valve for the L3200 and L3800s. Just the one and it works well when adjusted properly.

This is exactly what my dealer told me. And considering they fixed it, i believe them. I actually thought I was about to shell out $$$ on a Grand L hyd valve to eliminate the jerk...

I'm here in Houston and just got my L3800 from Allied Power Mart in Splendora. I do have the jerky 3-pt. hitch and would like to get it fixed. After reading other threads I thought it was a problem I was going to have to live with but now it seems something can be done.

Any one have a dealer in Houston that knows how to adjust this properly? And is this something that can be done in the field or does the tractor have to be hauled to the dealer?

Thanks!

The tractor will have to be brought to the dealer to be fixed. Contact the dealer and tell them about the problem. If all else fails contact Kubota Corp and they will have a service rep look at the tractor and advise the dealer on what the fix is.

 

[Rail Dawg]

My dealer is going to come and pick up my tractor to look at this problem. The service guy said he has never heard of this issue on the "L" series. Am I going to run into some roadblocks here or be wasting my time having them pick it up?

When they do pick it up what is the best way to ensure they get it fixed? If they call the tech support line at Kubota is that going to be enough for them to fix this correctly?

Thanks for the help with this problem. I definitely want a smooth 3-pt.

 

[Texas Fella]

If they call the rep or tech line, it will get fixed. They do not want to pic it up and do nothing to help you. I would give them a shot, give them a couple of days, and then call them and see what they found. Just my 2 cents worth.

OK thanks. It's an outstanding tractor save for that one problem.

It sounds like it can be fixed.

Thanks again.

Can you shoot a video of it and post on Youtube and link it here? Just to see how bad it is. They are not all bad... but would like to see what yours is like.

I went to the dealer with my mind set of leaving the tractor and not getting it back until it was fixed.I went for the "calm yet demanding" approach considering cussing and stomping has never got anything fixed for me before.. Then waited and then waited through the holidays. The dealer contacted Kubota which in turn said they knew there was a problem but I would have to pay for the parts. That led me to call Kubota Corp myself and get a tech to advise the dealer on what to do to fix the problem. It took several weeks with the holidays to get my tractor back, but it was all worth the wait...As far as how bad the jerk was, mine would literally lift the front-end off the ground when using it. Now i can lift a pail of water without spilling a ounce.

I've seen the jerk on an MX4700 and my MX5100 does it a little if I move the 3pt slowly. I think it does it less if the hyd. fluid is warmed up. Not sure what valve the MX series has, but for now, I've decided to just live with it.

[smweatherman]

Yes, my MX4700 is fairly rough if I try to make a small movement, but it isn't bouncing the front wheels off the ground with 1000lbs on the 3pt. If you move the lever two or three numbers on the indicator it travels smoothly. However, if you try to tweak a small raise on the implement it jerks a fair amount.

I would be interested how the valve and issue compares.
