Post pounder on a JD 4600

[leadfarmer]

I have a JD 4600, hydro transmission, with front end loader.

On the back it has two sets of hydraulic line connections with quick couplers that I have never used. In the cab on the right side, above the rockshaft lever, I have one factory installed lever that I assume controls one of these sets of lines. I still need to trace the lines and see which set goes where. There is no mention in my owner's manual about any of these hydro connections.

I really have no experience connecting hydraulic attachments to tractors, other than the backhoe I have for my Kubota L3400. I just connect to the only two lines it has (power beyond) and go. I know I have to keep these two hoses connected to each other to complete the circuit when I remove the backhoe, per the Kubota manual.

So now I have purchased a Kencove PD100 post driver to use with my JD 4600. Would I be correct to assume one of the sets of lines on the back of the JD is continuously flowing, like a power beyond? I guess if so, then it isn't designed like the Kubota, and doesn't need to be connected to itself to complete the circuit when not in use. I planned on removing the couplers and momentarily shooting some oil on the gravel driveway to confirm things.

I know the post driver return is supposed to route directly into the transmission sump, and the fill port/dip stick is conveniently next to the PTO. It would be nice if someone made a threaded adapter for this, but I can machine one if not. I will check out what threads it is, but I don't expect it to be a simple NPT thread. I just don't want to stick a barb end fitting in there and have dust and moisture able to enter. I should probably make sure the transmission housing has a working vent while I'm at it. Then to feed the post driver, I assume I want the continuously flowing connection, and not something controlled by the lever in the cab.

Please let me know your thoughts and experience.

Hello,
Not certain of your equipment / setup, but I believe you are describing "remotes" (hydraulics for controlling attacments). If you have '4', then you have dual remotes and there 'should be' 2 levers on right side by wheel. Each lever controls one set (2 couplers) of remotes. For example, on my NH tractor, (which has dual remotes-4 couplers)... for a side mount ditch bank flail mower, one set (hydraulics), moves the mower from behind to the side (in and out horizontally) and the other set moves mower (angle) arc from 60 degree down to 90 degrees up (3 point hitch raises and lowers the entire mower unit).

If your attacment has 2 hoses and quick connect couplers, they would go into the remotes.

Hope this helps?

So I figured out I just have one set of rear remotes. The other connectors on hoses at the back are just lines that feed a third function to the loader when connected to the rear remotes.

Should we be seeing a difference between the three pics posted ?? Looking the same to me.

And thanks for the clarity for the 3rd SCV function.

Yes, you just have the 3rd function option, no ‘power beyond’ is installed. You can achieve constant flow by bungeeing the lever in one direction or the other.

But, most post drivers require a free flowing line back to the tank to operate correctly, you will not get that through those couplers. You can make an adapter to put the hose in the fill port, that’s usually the easiest option.

Yup, I will run the return line from the post pounder into the transmission fill on the back axle. Luckily, it is threaded 1" NPT. Unfortunately, this filler neck bolted on the rear axle housing is made from aluminum, so I have to be careful with it.
