I know that this is an older thread and seems kind of worn out but I wanted to ask a question and thought this would be the best group to ask it to. How do you guys find the closing pressure of the grapple arm? I know that the hydraulic cylinder is small but the closing pressure on mine doesnt seem to be very much. I was cleaning out my paddock and had a pile of old hay, straw, and manure that I was trying to grapple out. When I closed up the grapple, it didnt clamp down very much. Is this what you guys are finding or could I be experiencing some other issue ie... air in the line, something wrong with the hook up or cylinder?
