Chipper hookup to tractor hydraulics

[Caco4x4]

DFKRUG, You suggest I now disconnect the 2 hoses at the chipper and put them into a bucket?
From what I´ve read on this forum I should bungy the auxiliary shifter in the front or back position.
Then start the tractor and see witch hose the fluid flows from and connect that port to the valve that has the shifter. The other port to the speed control.
IS THIS CORRECT?

I can't see from your pix: is one hose from the flow control valve connected with a TEE at bottom of the spool valve? Maybe you can annotate your photo with letters or numbers on each hose.

If your AUX valve is not detented, you will have to use a bungee cord or something like it to hold it in one or the other actuated positions. You have to find out where the OUT work port is. 2 open hoses into a bucket will do that.

Dunno what you mean by "shifter". Label your valves on an annotated photo.

I see no T´s, Shift is part of my ignorance, meant auxiliary lever.
Took a better picture and tried to mark them.
Hope it helps

OK, to me it looks like blue is the supply from the tractor, and pink is the return. Blue goes into the flow divider valve, with excess fluid going to the return port of the spool valve (yellow). I think that the spool valve has two return ports, where pink and yellow are connected, which acts like a tee. You should verify that, perhaps using air.

The short unmarked hose is the IN hose for the spool valve. To the left of that IN port is the adjustable relief valve.

Others may opine.

Thanks for the info, I am starting to understand a little more, I did the bucket thing and the flow from the tractor when the lever is pushed forward comes from the top connector.
If I understood right, the power from the tractor should go to the flow or speed control valve (blue) and the return is the (pink) on the 3 position spool valve?
So I should swap the pink and blue hoses at the tractor.
Did not understand the air test you suggest and don't know what the adjustable relief valve is.

First, the AUX valve on the tractor. Since you have found out which ports are the IN and OUT when the lever is in a particular position, then you can reverse the flow by just using the other lever position. Or switch the hoses around, as you say. Just don't get it wrong. You do not want to run the flow backwards thru the chipper valves. And, yes, you have to use something to hold your AUX valve lever the right way if your AUX valve is not detented.

I suggested an air test of your chipper spool valve to test that the 2 lower ports are connected. They probably are. The way the hoses came with your machine tells me how they should work. But, it has yet to be put into service.

Finally, the relief valve on the chipper spool valve. It is just to the left of the blue maker plate. If the feed roller easily stalls when you try to feed a branch, you will have to increase the setting. You do that by taking off the cap and turning the screw clockwise.

I have never seen a PTO chipper quite like yours. Nice you have hydraulic feed. I do not see a safety lever to stop/start the feed.

Is this how it should flow?

Late to the party but, yes.
Also that lonely single fitting is a return line to the tractors housing.
If you use that for the return from the splitter valve, then you can connect the inlet hose to any of your rear remote connectors and as soon as you move the right control the correct direction everything will work.

Using the remote return line simplifies the hookup.

I bought it from Jinma with the tractor. Seems to be pretty solid. we´ll see when I get it running

Do you mean the fitting circled in white?
How does it simplify hook up? excuse my ignorance.
Pink goes there?

Yes, that should be a non-restrictive return to the tractor. That fluid doesn't have to return through the hydraulic valve and it's small orifices.
Then because it is your return you are left with a single pressure hose to connect, it can go to any of your remotes, it doesn't mater which one. When you activate your remote one way is not going to do anything and the other way will provide fluid flow. It eliminated the possibility of reverse flow to your chipper as either one will work.

 

[Caco4x4]

Excellent!!!
So I can´t screw it up and blow something up.

If that fitting circled in white is indeed a port on the tractor that goes into the sump, then that IS a better way to hook up the return line. I would do it that way. I wish my tractor had an easy return port like this. Some machines have them and some don't.

Good suggestion, Lou.

Now on to operation. I am familiar in general with chipping, but tractors and hydraulics are new to me.

I think I'm fairly clear now with the feed mechanism. I start the tractor and activate the roller by tying lever in the forward position.

Unfamiliar with PTO. I have dual clutch and 540/1000 pto.
How should I engage the tractor pto to the chipper?
What Rpm should the tractor be at.
Do I release the clutch slowly?
Is the PTO shaft connected right?
Protector chain ok?

Start tractor. Set engine speed control to idle. If you have a foot clutch, press it. Then shift PTO selector to 540. Then release clutch slowly. Increase speed after engaged to 540 PTO speed, often noted on tachometer.

Can't say by looking if the PTO driveshaft is properly locked onto each splined shaft. You can tell. The plastic idiot shield is supposed to stay stationary with the chain they give you, properly attached. It will wear out eventually.

Thanks again

Upsss, must have done something wrong.
Now I have 2 three point hitch controls.
Remote connected to chipper rises and lowers the TPH

interesting?

HELP!!

Wondering if that single quick disconnect that we thought is a direct tank port is in fact a single acting port meant to feed, for instance, a dump trailer. It's also a somewhat common thing to do.

I would change that line back to the remotes and give it a try.
