    John deere 4020 3 point jerky when raising

    It happens all the time, whenever 3 point is being used. I do have a manual and will dig into that deeper. I assume it will tell me how to set the stand by pressure also. thanks

    4020 3 point jerky

    There was a post on here from a Gerald that had a check valve upgrade to help losing hydraulic pressure but link doesn't work anymore. Anyone have that info?

    4020 3 point jerky

    I just purchased early model 4020. Changed all fluids, filters, and screen. 3 pt raises slow and is jerky. Load/draft lever is broke off so currently looking for one. All other hydraulic functions work fine. Any thoughts?
