In this tractor with loader, when I try to feather down it'll bounce and jerk and bounce and jerk repeatedly and in a rhythm. It gets worse the heavier the load I'm moving around. I've turned in the adjustment screw on the valve bank at the back of the tractor. It slowed down the full valve down speed, but didn't touch the rhythmic jerking, maybe slowed it down just a touch. It'll run smoothly down when valve is fully open. I can feather just fine in the up direction. Nice and smooth from wide open to just feathering. But not going down!
Anybody ever run into this? It's the same exact hydraulic system as what's on the earlier models like the 2-105.
