Thanks for your response. I hooked the HX10 up to my NH 6610S for first time and when I attempted to lift i though the top link was binding it and wouldn't allow it to lift. Front of cutter came up a few inches and stopped. Front tires also came off ground a few times. I probably have a hydraulic issue and/or cutter is too heavy for the tractor. I had just change hydraulic fluid and filter - lift is bouncy with light equipment.
Not trying to be condescending, surely the OP knows which lever is Position Control and which one is Draft Control??
He said lift is bouncy with light equipment. If it is bouncing with light equipment, I am curious what the draft control is set at trying to eliminate one thing at a time.
