Weird hydraulic outlet/3pt question

[Builder]

Trying to figre out my new (used) Challenger 3pt hitch & remote outlets. I have no operators manual.
There's no dedicated lever to raise/lower the 3pt hitch. There's 2 spare levers supposedly connected to 2 sets or rear remotes. However, 1 of the (2) rear remote levers makes the 3 pt go up/down.

To add to the confusion, there's a 3rd set of remotes that I'm pretty sure were added to power a subframe mounted backhoe. The backhoe was removed before I bought the tractor. Under this set of "backhoe" remotes, there's a hydraulic line, about 24" long with a female connector on the end. This line is plugged into the "male" side of the backhoe remotes. My guess is it is a constant feed of hydraulic fluid to power the backhoe.

What I can't understand is why one of the standard remotes lifts the 3 point? Is there something obvious I'm missing here? Can I utilize the backhoe remotes for anything else? How can I get the remote that lifts the 3pt back to running an outlet? How can I get the 3pt to lift without losing one of my "remote" levers?

I think I'm losing my mind. There must be something obvious I've overlooked.

Not sure about the other "remotes", but the proper terminology for what you described above is "PowerBeyond" and should be a constant flow of fluid whenever the tractor is running. Do NOT start the tractor while it is unplugged!

Uses for this could be a backhoe(obviously) or a 3PH mounted logspliiter or ant other implement with it's own valve.

First, congratulations on your purchase! I know you've been looking for the right tractor for a while, now.

Have you tried Ransome Cat? They should be able to get you an operator manual and a shop manual if you need one.

If the previous owner had a backhoe on it, the hydraulics for it should have been from a power beyond block, which would require a hose connecting the input and output ports when the backhoe is not attached, to prevent dead heading the pump. There would be no lever controlling the power beyond. If there are also two pair of inlets and outlets for valves, each pair would be controlled by a single lever, so there should be two levers for them. The three-point hitch should be controlled by one or two additional levers, depending on whether the tractor is equipped with draft control. Hope this helps some.

Good luck

Thanks. Yes, I have already talked to Ransome CAT. They have a name which we kind of laugh about here. They sure require lots of "Ransome" to work on your equipment!

As you can imagine, there are 2 levers in the cab marked "1" and "2" and 2 sets of remotes on the rear of the tractor marke "1" and "2". Weird thing is that one of the remote levers lowers/raise the 3 pt hitch.

There is a working draft control which regulates the height or depth that the pt arms can go.

It's as if someone removed the lever to raise/lower the 3 pt (at least after going over the machine for about 2 hours, I don't see it) and used one of the remote levers to raise/lower the 3pt.

Where the heck is the lever to raise/lower the 3pt? Was it "lost" or sacraficed somehow for the backhoe power beyond circuit? can i get it back?

The PB circuit is not related to the 3PH at all...

Just a guess, but could there be a diverter switch that changes between the rear remotes? So that one lever works both remotes. Your 3pt is working on one lever and you have the power beyond figured out. Maybe your just overlooking something simple.

Not familiar with the Challenger brand of tractors but on my Jinma Tractor I have what is called a 1/2 remote. Here it is in a nut shell.

The half remote uses the 3 point lever to operate things like dump carts, hydraulic lifts on disc or plows, ect. Its power up gravity down.

I have a flow control knob which on my tractor is under the seat. You use this knob to control the flow of hydro fluid to the 3 point. If you have a heavy implement on the 3 point you need to choke the flow down to prevent it from dropping quickly. To do this you close the valve vial the knob.

If you close the valve fully via the knob you then divert the fluid to the half remote. Your 3 point will now be in the full down position with no control over it. When you move the 3 point lever to the raise position it sends the hydro fluid to the half remote to operate something that needs pressure up and gravity down. When you move the 3 point lever to the lower position it allows the implement attached to lower via gravity.

Hope this helps.

That's interesting because I do have a flow control valve under the seat which regulates the speed at which the 3pt hitch arms drop, but I thought all tractors had them.

I still don't quite understand the "1/2" remote description. I can't imagine why the 3pt arms have no seperate lever for them in the cab.

Another thing i noticed is that there is a slot next to the seat where it looks like it would go, but there's no decals or evidence that it was once there and removed.

I have the same setup as you do with the 24" piece of hose completing the circuit on my power beyond as described. Here is a pic. I can use mine for things like a backhoe and I also use them for the log splitter I made.

Like stated before, never remove or try to start the tractor with the jumper hose in place or a open center hydraulic accessory attached.

I am guessing your tractor is plumbed similar to mine. Like I said, on my tractor 2 functions share one lever. Its either going to control the 3 point or the 1/2 remote depending on what position you have the flow control valve in. Its either one or the other.

I actually took off the 1/2 remote on my tractor and put a plug in its place. I need the space on the back of the tractor to mount a rack to hold my chain saw since 50% of the work this tractor sees is in the woods logging trees. I figured I would never use it but if its needed I would reinstall.

Also who make these tractors? Are they a Cat product or are they made by a third party like so many things and re badged?
