Your model, L 3000 DT, is not included in this issue (as far as I know). So it might be the case you need to change the fluid and clean the screen. How many hours do you have on it and the last time the oil was changed? The other reason might be air getting sucked into the system. You might want to start another thread in the kubota section, post photos of the area by your right foot, looking for a hydraulic return hose. I don't know what the L 3000 DT is like, so just guessing now.

True it is subjective, we are just trying to figure out why some models are more subjective than others and if there may be a fix that we may be willing to pay for. You don't gain market share when you begin to say things like 'it is what it is'. From there, you begin falling.
We are trying to see if there are some out there that are not jerky. If some of them work just fine, then, yes, some ARE broke... Or actually, maybe just out of adjustment and can be corrected. We are just looking for ones that go up slowly and have NOT been corrected by getting a Grand L valve installed.
If they are only out of adjustment, why did kubota install a Grand L valve to "fix" the problem, instead of properly adjusting the valve that's in the tractor from the factory???
Really looking forward to MessickFarmEqu video...
I would love to know that the valve can be adjusted to correct the jerkiness and that there are smooth working ones out there.... they are too busy playing with their tractors to come on TBN.

:laughing:Never really used my 3ph much til last year and didn't notice anything unusual when I did. Got a 3pt cement mixer and had a lot of cement to pour, thought it was me or mine that I couldnt lift the hitch smoothly. It was the first time I had ever tried to rise the 3pt slowly and it was jerking all over the place. Later that month I discovered TBN and found out it wasn't only me and mine. Relief to know that I had great company in my not so much misery:laughing:
Seriously at least for what I do it is fine the way it is and is only jerky when I go slow on the lever.

What exactly is the issue? My L4200GST 3pt is smooth, at least when I lift an implement all the way up. I'm only running a snowblower and a rake, so its mostly full-up or full-down. I have done some fairly precise adjustment while raking before, and I did get a funny bounce once and did think of this complaint, but in general I think my hitch operation is pretty smooth, or at least smooth enough for me not to be bothered.

The issue is the amount of jerking/bouncing the implement incurs when being lifted in a slow or small increment.
Imagine you have a bucket of water or a heavy item like an engine block on a chain hanging off a boom and you are trying to lift it to a specfic point in the air in a slow smooth motion. The problem is that with these problematic 3pts, the water is bounced out of the bucket or the engine is jerked to the point the chain goes slack with the engine bouncing at the end of it. If I had not read this forum, I might have chained something heavy to a boom pole and tried to lift it. Not being aware of the problem it could have snapped the chain when it bounced and cause damage or injury.
When doing things like mowing, it is not so big a deal. When trying to smooth a surface and make slight adjustments to the height or lift heavy objects with a boom it becomes an impediment or safety issue. In my conversations with my dealer, these types of uses were not discussed since they had not been considered, so he did not mention the 3pt issue to me.
Some of us were ignorant of the issue before buying and did not consider testing these applications of the 3pt, others did not anticpate such use and did not care before hand. Regardless of why it was not tested, the fact is that needs expand and uses change and we don't want to sell our tractors everytime a new use comes up. We would like them to function acceptably for all normal uses. We don't expect to have every capibility in the universe, but we do expect all normal capabilities.
If I buy a tractor with a 1000lb lift capacity and someday need 1500lb capacity, then fine. That is a scenario that is beyond the scope of my inital purchase and I need to buy something else.

I agree that lifting a bucket of water on a boom or an engine or some other item on the end of a 3 point boom can be difficult with an inching valve. However, it must be considered that neither one of those items is "normal" use for a tractor. If you disagree with this, then think about the fact that no major tractor maufacturer sells 3 point boom type lifts. Yes, there are outside companies that do, but they are in business because of the low quantity of units sold. If everyone used that type of equipment on a tractor, the "major" players would get involved and sell some on those and make more money. Just another thought.

These L series tractors do not have an inching valve. They have a Position Control valve.

I will check on the exact type of valve that is in the L3200/L3800 and see what I can find out. An "inching" valve is a postion control valve, by the way. Some notes on the function of the 3 point lift arms. As you move the lever, the lever pulls out on a spool, thus allowing oil flow into the 3 point piston. As the piston fills with oil, the 3 point arms begin to raise. As they raise, the feed back lever pushes on the spool, moving it to the nuetral position (no oil flow). This stops the 3 point arms upward movement. When trying to "fine tune" or make "fine adjustments" to the 3 point, it is critical not to move the operating lever erratically or overly fast. This causes "full" fluid flow (quick 3 point movement) followed by an abrupt stop (when the feed back rod returns the spool to neutral). This will cause more jerkyness, if you will. I know and understand that this in not a complete answer of the issue, nor does it eliminate all the problems discussed here. I just thought I would share, and maybe it will help someone.
