:welcome: to the forum, Unfortunately I think we need more info in order to properly advise you. Are we talking about a front end loader or 3 point hydraulics?

Welcome to TBN.
Have you checked to be sure hyd oil is at the full mark?? How long since hyd filter was changed? Does tractor have "dual-power"?
