What you are showing in the video is very common to low cost open center hydraulic circuits,,
The reason the bucket moves like that is air in the hydraulic cylinders, and hoses.
Two $1.50 restrictor fittings will cure the issue, and, depending on how you use the tractor, possibly only one is needed,,
Or, I just hold the lever in dump for an extra 2 seconds and it's solid. No biggie in the overall scheme of things! I mean most of us are not using these low cost machines in a commercial setting. Anyone who is doing commercial work, needs to look up the food chain for a machine that has high performance closed center hydraulics (or equivalent).
There is very little air pulled into the cylinder actually. The weight during dump pulling on the cylinder pulls a void (vacuum) that holding the control valve in dump keeps adding fluid to fill the void until the cylinder is solid.
You are correct, low cost hydraulics to meet a price point is a given. Understanding this prevents most frustration.
