3-Point Hitch Poll for Jerky Hitch models!!!

I was told it's inside the hydro assembly above the rearend. I noticed a new gasket was installed on my tractor, so I know they went inside to adjust.

Thanks, I may look into it. To be honest, I would have never known, checked or thought about it, if I had not read it here first.

The valve is bolted to the underside of the casting that contains the rockshaft and lift piston and cylinder. You remove the seat, the seat frame, etc to get to it.

I think there are about 10 bolts that hold it in place, and a gasket between it and the transmission case.

Spent some time on the L3800 yesterday. Have posted before that my hitch is jerky, but only when trying to raise slowly on purpose and never seem to notice it when actually using it in "the field". Someone else mentioned that it goes away when it is warmed up and that may be what I experience because I box-bladed my driveway and recontoured some of my yard yesterday with it and was able to fine tune on the fly with no issues noted at all. I guess mine must be minor.

I might would pay $100 to have this fixed, but would think if it is a persistent issue, that Kubota would take care of it on it's own under warranty.

I might pay $100 to have it fixed as well on my L3200.

I did install an hydraulic top link and it helps a lot when using my box blade or when hooking up other implements.

I do enjoy my L3200 ...except for that jerky and potentially dangerous 3PH.

5 more months of use on my 3800 and the jerkiness is still not a problem for me. Mine must not be near as bad as some out there?

For me, it was easiest to upload my videos to youtube and share the link here.

My L3700,
Before : Kubota L3700SU Jerky 3pt Hitch - YouTube
After : L3700SU Jerky Hitch After Dealer Repair - YouTube

I've looked at a few vids now and will just quota the above with links.

Mine is much closer to the 'After vid' than the 'Before vid'. Only a little jerky when raised Very Slow.

NO, I could not live with a hitch as jerky as the one in the 'Before vid'.

I'm starting to see what ya'll mean by "jerky hitch"...

If yours is more like the "after" video. then yours is fine, mine was like the before video. Really bad.. original dealer not interested at all. second dealer very interested in helping me, but He went to Kubota regional and they had no fix and no money for any warranty valve replacements or warranty work of any kind on this. Of course he could not do any work for free, but was willing to give me a good rate, and a good price on pickup and delivery.. Not bad considering he never made any money off of me on the original sale. He was very sympathetic, but in the end there was not much he could do.
