Been searching posts about hydraulic hold positions and now I am more confused. I have a 3 pt on my wd45. I cannot hold it at one position. It wants to drift up or down. Can I fix this?

Thanks!

Set the hydrualic control lever at the hold position with a load on the arms and shut the tractor off. If the arms stay in place, the linkage needs adjusted. If they still go down it's time for a new ball and seat in the hold position valve. This assumes that the pump is set to hold like Norm said.
