The blade on my D3B barley moves when it does it just bumps up slow. Everything was working fine I changed a hyd line and then the next day after running it for a while the blade started doing that hyd fluid is good the pump sounds like it's winning when you try to move the blade. Could my hyd pump be bad all of a sudden like that? Or any ideas what it could be.
It is possible it could be a bad pump. Could also be a failed relief valve. If you have the gear to do it I would check your pressure and flow specs. Does engine rpm have any effect on it? All blade functions are slow/non existent?
