John Deere 3720
I have been spending a few weeks reading on this forum and green tractor talk to see if I can find the answer to something not even my dealer knows.

Last year I purchased a 3720 from the Dealer with a 485 Backhoe and Grapple Bucket. The Dealer delivered it to me and said that if I want to use my backhoe with the Grapple attached to the FEL then I have to disconnect the Power Beyond Loop that feeds the 3rd SCV EH and plug in the Backhoe pressure line. I didnt like this at all and I still don't. How does John Deere design a 4-1 bucket with front FEL connections and 3rd SCV EH and not allow you to use the backhoe without having to disconnect lines?

I believe the Dealer has something set up wrong.

Thank you

I think one should be able to plumb the PB block in series with the BH. I'll need to do some research.

Is your tractor cab or OS? Does this PB resemble yours? Is the 3rd scv plumbed similar to the 2nd photo? Is grapple bucket built by JD as I didn't locate it in the 485 PC??

Open Tractor no Cab and the PB is just like that and the 2nd Photo also is just like that, however in the 2nd Photo, Hose #1 is not there. It is being fed from the Power Beyond return line which is basically #11 in the first Photo which goes into the pressure port of the EH 3rd SVC. Grapple bucket is not built by John Deere. All the lines and kits you see are factory and was an option in MY2011 3x20 series tractors.

I have very limited BH repair experience so does grapple bucket go on FEL or BH? I think FEL but I want confirmatiom
