3-Point Hitch TC29D New Owner

That lever likely has a detent. . .

James, the NH remote levers for compacts do not have detents. They return to center unless the return spring gets gummed up. I had one get rusted up inside due to rain water leaking in. It would stick wherever I put it, but that is not how it is supposed to work. The larger NH utility tractors have detented remotes, but not on compacts unless NH has recently made them available.

Well, if there is no detent position on the valve control lever, I guess he needs to take off the bungee cord then.

I have unhooked the log splitter. The hydraulic lines from splitter was attached to the side of the tractor. See pictures.

My first thought is there is no front end loader on the tractor, and no control valve either on the tractor, the log splitter was hooked to pressure and return to the 3pt? and that now with them unhooked the pump will be deadheaded? If I am right ( and I am NOT an hydraulics guy by any stretch) you would have to run a hose between those two fittings to make the 3PT work again. More pix would be great. of the other fender controls. showing the 3pt lift lever and any other levers. and the picture of the seat was nice but I didn't get anything from it. Hope someone else weighs in here with more experience.

You may have deadheaded your system by taking off those hoses. I wouldn't run the tractor until you got some advice.

Typically you need to put a tie in between those connectors, or turn a valve on that block. What'll happen is that you will lift the relief valve continuously, heating the fluid, and/or ruining the relief valve.

I was thinking the same thing, I think the NH TC29 is Open Center, and if so it looks to me he is in a deadheaded situation now, with the splitter off, and I am thinking there is no remotes and no control valve on the tractor. To the Original Poster, I dont think you should start the tractor until this is resolved, by someone who know this model of tractor well.

Joe, I'm not certain, but I think the valve you disconnected is the system diverter valve. That valve is normally used with a front-end loader and your tractor doesn't have one. Since your tractor has no front-end loader, somebody plumbed in the splitter instead of the FEL. In this configuration, the 3PH cannot lift (At least I don't see how). There's a valve that needs to be moved from the 10 o'clock position to the 2 o'clock position I believe and those connections you remove can then be capped. PLEASE KNOW THAT I AM NOT COMPLETELY SURE OF THIS. I need to study the TC29's 3PH some more. I think you are walking a very dangerous line doing connections without knowing for sure.

There's one big question I need answered. Has your 3PH ever worked since you owned the tractor? Was it working and then stopped? It's not clear whether it lifted before or if you just dropped it and it will not come back up.

I have to be away from the computer for the rest of today. Perhaps someone with a TC29 or TC33 can advise you much better than me. I was talking about remote hydraulics and your tractor doesn't have them installed. It's kind of a shade tree setup to make the splitter work and I'm just not really confident in advising you at this point.

My TC29D has a Woods backhoe that runs off of the tractor's hydraulics and is mounted with a subframe.
With the backhoe mounted, the 3 point would go up and down normally,when I removed the backhoe, the 3 point would no loger work, and, interestingly, the tractor was hard to start.
It turns out that because I did not connect the two hyd lines from the tractor back together after removing the hoe there was no flow, so the system was bypassing (and making it hard to crank the engine?)

My tractor also has a FEL, there is a frame mounted diverter valve on the right hand side just under the hydraulic pump it looks like an aluminum block with hydraulic lines coming out of it. That valve has a two position adjustment, it looks like the head of a screw and it has a slot cut in it. That slot will be either in the 10 o'clock or the 2 o'clock position. Whichever position your valve is set to you might have to rotate it to the other to make your 3 point work.

If you don't have a loader,the diverter valve must be in the 2 o'clock position for the 3pt to operate.

Question to some of the more hydraulic experienced among us:
Wouldnt a short piece of 5000 psi hose with the correct (Parker?) fittings on it placed between the fittings get the 3pt back to working? I am guessing the original owner had that hose somewhere. And another question. arent those elbow fittings ordinary galvinized pipe fittings? I cannot tell for sure but if they are, isn't that a no-no for 2 reasons. The possibility of zinc galv. flakes getting into the fluid, and the fact they are not really rated for the pressures involved? These are actual questions not trying to act like I know more than I do, as I dont know much. I have learned a bit (thanks to you great guys here on TBN, but need to know more).
