Greetings and a question from a newbie to this site who's been lurking for awhile.

I have a Deere 5320 to which I am about to mate the factory-correct Deere Model 49 bakhoe. Got a good price on a never used unit off E-bay. My 5320 came without any rear hydraulics (yeah, I'm certain). I've talked to two Deere dealerships but it being the tail end of hay season it's going to be some time before their service backlog clears. So I'm thinking about plumbing in the rear hydraulics myself. I'm relatively handy with tools. So, to my question: do we have any JD mechanics lurking about that can help me with which parts/manifolds/lines I need for this install. The hoe requires Deere's Power Beyond kit, whatever that might be is not clear from the name. There are two hydraulic lines to the hoe plus a return line. One of the service departments mentioned at least two ways to plumb in the hydraulics, one giving much greater responsiveness to the backhoe. One thing is certain: I don't want hydraulic lines hanging where brush can give me grief. Hard lines, as much as possible, are the way to go. One or another service department talked about mounting a manifold on the ROP, but realize I was also talking about installing top-n-tilt cylinders on each of the rockshaft arms--until one of the dealerships mentioned parts and labor for the whole show would range between $3,000 to $4,000.

Any help/suggestions appreciated.
Thanks everyone.

That quoted price is really way too high. I would not be doing business with that dealer. However, you did ask for hard lines which would be expensive to run but not that expensive.

Why don't you just buy the JD kits and install them yourself?

I am sure someone here can give you some less expensive alternatives.

Hi Mad,

Yeah, I try hard to avoid that dealer. It is the major JD dealer in the state. Their prices are high and their salespeople not the most honest (have been downright treacherous in one instance on a many-many-thousand-dollar purchase).

I will happily buy the correct parts kit, when I figure out what that is. Both dealership give me the idea there is multiple ways to approach the solution. Thought I might find a Deere dealer lurking about this site. It's about an hours drive to see these dealers and thought I'd do a little homework before I showed up.

Best,

Jack

Thanks, Mad. This MN site looks like very useful reading. Gonna look over the printed copy tonight. Can't hardly wait to dig with that new backhoe. Got some gophers I want to root out. Come to think of it, the hoe would sure make a useful diesel-powered clam gun, too.

I installed the Power Beyond kit on my tractor and it took about four hours. The majority of the work was removing all the sheet metal to access the ports. I paid just over $200 for the kit and it consisted of fitted hard lines all the way to the rear mounting bracket. The backhoe will require an additional return line that dumps directly to the sump. This is probably what the dealer was referring to as the better performance option. In my case the additional return line was simply a piece of 90 degree pipe with a QD port attached to an unused plug on the rear housing. I would suggest doing it yourself. It's pretty easy and you'll probably learn more about your machine.

Yeah, that's about what I thought.

I also gotta take a look on this site for info about plumbing in top-n-tilt cylinders on the top link and rockshaft arms. If I do that work later I don't want to have to replumb the hoe hydraulics. I keep hearing about "dual rear remotes". Now, I can count. Most days. But I seem to gather that dual rear remote involves more than just two positive pressure lines and one return line.

The dual rear remotes lines are 2 sets of "A" and "B" ports that are fed from two open center control valves...usually. The "A" and "B" ports are both presure and return depending on which way the valve is posiitoned. When the valve is centered both ports are shut off. A power beyond is simply a pressure and return line that needs to be jumpered together when not in use.

Gizmo, this type of open center valve, that seals off all control ports when centered, is termed a tandem center, I believe.
