Apologies up front for what sounds like a stupid question, but I have to ask. Is the aux valve on my 742B an open-center, dual-action valve? I need to attach a root grapple with a single dual-action cylinder. Can I connect the cylinder hoses to my aux quick connects, and have dual action performance by pulling the steering lever to the left for action A and pushing it to the right for action B, or do I need to insert another valve ? IE, go from quick-connects to new valve to DA cylinder? I have only used the auxillaries for a tree spade where the hoses from the quick-connects go to a 7-spool bank of open center valves. The performance of the tree spade hydraulics is the same whether the steering lever is angled to the left or right. Thanks in advance for clarification.
