aux hydraulics

Hello all, I have a ASV RC50 with aux hydraulics and I believe the machine is equipped with high flow aux. I recently purchased a log grapple and am experiencing a rapid closing and opening effect. Soo much that im afraid something is going to break off the grapple. When my machine was recently at the dealer for some maintenance, I had them hook up my machine to one of their twin full sized grapples to make sure the aux thumb controls worked. When they operated the twin grapple it opened and closed much slower. It was very controlled. I was wondering because my grapple is a single piston, single grapple, is this the reason its reacting extremely fast and if soo, if there some kind of inline reducing valve I can obtain from the dealer?

You can put a flow control on one of the cylinder lines. It can be a adjustable type or just a washer type. The washer kind are just washer with a small hole to reduce the flow that you put in one of the fittings. If you have access to a lathe you can make one. Adjustable ones should be available from a ag dealer or someplace like Tractor Supply.
