I was trying to hook up my new grapple bucket and when I activated the grapple, I sounded like the pump was staying in motion and now for some reason the boom will go up but wont go down and I can tilt the bucket in but not out and the grapple will open but will not close unless I switch the hoses around. What is odd about switching the hoses is that after doing so, as soon as I start the machine the grapple closes by it self with allot of pressure and does the same after switching again , it opens with allot of pressure. When I disconnect the quick couplers for the grapple, I still don't have down pressure or pressure to lift the bucket . Could something be stuck open somewhere in the hydraulic system?
