    Hydraulic problem

    After 3 hours of work the lift starts to make small jumps.
    With a cold car the next day, everything is OK.
    What can it be and what can I do?

    I enclose the video

    Welcome,
    Your video does not play, and I'm not downloading it from your link...sorry.

    We don't know what machine you have, but I'll guess a 1-series. Here are a few thread with simular issues. There was a know problem with these for awhile.

    Agree with kennyd!!

    What tractor model??

    When you say lift, do you mean mmm lift, 3 point lift, or FEL lift.

    You can set up your tractor model and accessories in a signature so it will be included in your post This tells you how to set up a signature: https://www.greentractortalk.com/for...our-posts.html

    I watched his video on my iPad, you just have to wait several minutes for it to load up. Looks like a 1 series, has a 3pt scoup/bucket on back. The tractor is idling, nobody sitting on tractor. The 3pt is raised up and then all of the sudden, it will maybe drop an inch and bounce/hunt up and down for a second and then it will stop doing it & then 5 seconds later, it will do it again. I’ve never seen anything like it before.

    Sounds as if rockshaft piston seal or RS control valve is leaking causing a problem nicknamed as 3 pt hiccuping.

    If you would reveal what brand/model tractor you have then it would be much easier to correctly answer your questions.

    If RS piston seal is leaking more than likely the housing that raises 3 pt hitch arms will require removal from tractor for repairs.
