Hi, I have a 6600 (1978) and header is a 918 flex. Header height control is working but is very slow dropping head to the ground. Any thoughts. Is there a way to check if both cylinders are working on the head.
Thanks for any help.

There is a rate of drop valve under the cab that you will have to adjust. Just go from your cylinder hoses up and you will see the valve under the cab on the combine frame. Screw the # 6 in to slow the flow.
