lifting valve bulltra B1-14

[bowmore]

Hello i have a Bulltra B1-14,
since a few weeks the lifting device valve is only working at the end of his course. ( i marked this green on the picture)
before the 3 point hitch started to lift immediately when i moved the stick, now only at the end.
This i much more difficult to install the height that i want.
it is still possible to lift the tools at maximum height.
anyone have experience with this?
i live in French.

today i continued my research.
oil level is ok, i found he hydraulic pump behind the fuel filter.
i also found a few screws around the lifting valve, should i try to turn one of these or is it a bad idea?

Sorry the B1-14 is a little different than most of the kubota tractors we have here, so my information is mostly guessing.

I would check that the lever has not come loose from the control shaft and rotated on it.
The other thing to check is proper operation of the feedback linkage, it will also do some odd things if messed up.

If you could give more pictures of the control valve that might help to get you better answers.

thank you for your intrest for my problem.
The lever and the feedback linkage are wel fixed , they didn't came loose.
I tried to make more detailed pictures from the front and rear side of the valve.
it seems to be such an easy system, only the lever and the feedback linkage, no electronic control or solenoid valves.

today i had some time to remove the valve and also to check the oil and the oil filter
Oil and filter seems ok.
The valve also seems ok, but i didn't had the time to open it completely.
i needed the tractor to feed my horses.
After reinstalling the valve still same problem.
Next time have to open te valve completely, or i have to try to turn the screws on the valve and see what will happen.
if someone have some suggestions please let me know
