When I raise my backhoe or swing the backhoe from side to side the hydraulics slam so hard it is almost impossible to move the boom smoothly. When I use the other levers - boom extension/bucket or outriggers the hydraulics work smoothly. But when I use the lever to raise the backhoe boom or move it side to side it hits so hard you lose have the load in the bucket. If I am really careful and ease the control lever I can usually avoid the violent slamming but it really slows down the project. It only seems to be a problem on the one control. The boom, the grapple, mower and other backhoe controls seem to work smoothly.
The oil level is correct, filter is new so I think everything else checks out.
Any ideas? As is, the backhoe works but is very unpleasant and hard to operate.
