I installed the LVA16893 line and all is perfect! Thanks. Next problem. I got the power beyond kit to install now and I have the same issue. The kit would work great if I didn't have the 3rd, 4th & 5th kits installed. The lines supplied are for a bare tractor without any additional service valves. JD110 would you happen to have another diagram?

Thanks Jd110. That is exactly it. I have the 1 line, just need the other 2.

Thanks again JD110. Just thought I would toss up a picture of it all assembeled. You part numbers were perfect fit.

Looks Good.
What are the 2 manual valves for?
You don't get over to the "other forum" any more? I posted a document for you a couple of hours after you were asking about what parts you needed, but I see you never logged back in.

Ah, good question. I was rigging up a grapple for my bucket and I want to run a hydraulic thumb on my 485. I was just going to plumb the thumb into the 3rd quick couplers and then when I want to use it I can just shut off the flow to the front end grapple. I may just use the 4th or 5th spool instead. I am just in the process of building a thumb now, so that will probably be a week or two away. A hydraulic thumb is so nice for placing culverts...

Have you played with the 485 yet? I've considered getting one, I just want to make sure it is a "real" backhoe. I wonder if JD will ever offer a hydrulic thumb. I'm curious to see what you come up with.

Yes, I have played a bit. I dug a 40' trench (seen in pics) it's about 4 1/2' deep at one end and tapers down to nothing on the other. The gas company had flagged a gas line crossing about 1/2, but no reference as to how deep it was. I put in a 16" culvert. The whole thing took me about 3 1/2 hours, including digging near the gas line by hand with a spade, and buring the whole thing when done. It's a pretty decent back hoe. My biggest complaint is I am used to the ISO pattern, so the dipper and the boom are backwards for me. It's hard to teach an old dog to change. I'll post something when I get the thumb on and running.

Does it have the "creep to reposition" feature? If so, can you reach through the window to run the loader up and down? I have an open station, I could probably use a stick or something. One thing that disturbed me a little bit after seeing how the hydraulics are plumbed up (on mine), is that it appears that the power beyond will disable ALL rear hydraulics when the hoe is on. I was aways under the impression that the PB was plumbed AFTER the rear SCV's but BEFORE the rockshaft. It actually is BEFORE all of it. I thought it would be nice if the grapple would still work at least (3rd EH SCV). I could see wanting to dig up a stump, then carry it off with the loader/grapple.
How is yours plumbed? Mine is: Pump, PTO clutch, Mid SCV, PB, 4th & 5th Lever SCV's, 3rd EH SCV, then Rock Shaft.
