power beyond port

[gmason]

I've been told I can connect a 3pt backhoe's hydrulics to the power beyond circuit from my 16LA loader on my TC35DA. Has anyone done that or had it done?
Can you post some pictures, or some good instructions? Is it located pretty close to my FEL controller?

thanks

This isn't a huge amount of help but on my TC24D the 3 point hitch runs of the pb port, and I have to disconnect it to connect to the BH. On the rear axle is a return port.

As I understand it that most NH dealers do it this way and there is a kit they get with all the necessary parts. My backhoe is done this way but i dont have it yet for pictures. i looked at it and basically there is a line that goes up under right foot and hooks into 3 Pt. hitch line and disables that which you dont need anyway and the other line is a quick disconnect right near where the remote hydraulics area is. I dont know exactly where they hook but 2 quick disconnects and your up and running. No need for rear remote and the best possible pressure to run Hoe. I can post pics next week when i get tractor.

I have rear remotes on my TC 55. The dealer said to just connect the hoe to one of the remotes and tie the remote handle back to open the circuit. This will give you a constant flow for the back hoe to operate. I hope to try it this week to see how it works out. If it does my yard is going to look like a large prairie dog gathering.

Gary,

These instructions will work for all versions of the NH TC35,40, & 45 tractors with either the 16LA or 17LA installed.

Take a look at the hydraulic manifold inside your right rear tire just above the axle. This is the manifold that you'd attach any rear remotes to. The outer cover plate normally comes with just one hyd (male) QC fitting screwed into it. This is the fitting that your BH's short hose (pressure out) will connect to.

If you have any rear remotes attached to that manifold then you will have to get a hose kit that includes a replacement cover plate for that manifold. (I know that Woods has one shown in the photos) This replacement cover plate must include both the pressure out (male) and pressure return (female) QC fittings. The BH's long hose (pressure return) would connect to that female QC, but since you probably don't have the modified manifold cover plate the BH's long hose will have to be routed forward over the axle and connect to the hyd hose coming from the FEL controller.

NOTE: If you do have rear remotes and don't get the modified cover plate then the rear remotes will not work when the BH is connected.


Pictures will hopefully be the 1000 words to explain this.

This is the modified hyd manifold cover plate inside right rear tire for use with rear remotes. The original cover plate will be missing the red highlighted fitting.


Connect BH short hose (pressure out) to the male QC on this manifold cover plate. The BH long hose (pressure return) will connect to a female QC either at this modified cover plate or up forward to the FEL controller's hyd hose.



Looking under FEL controller, you will find two steel hyd lines and one hyd hose coming from the FEL controller and connecting to the hydraulic block manifold/diverter valve.



Close up of hydraulic block manifold/diverter valve. Disconnect the FEL hyd hose from the hydraulic block manifold/diverter valve QD and connect it to the BH long hose (pressure return) that you routed forward over the axle.

When you remove your BH, make sure that you reconnect the FEL's hose back to the forward hydraulic block manifold/diverter valve.

If you did by chance have the modified cover plate and used that instead of the FEL hose, then those QCs would need to be connected to each other. This is necessary to prevent your hyd system from dead heading. BAD

I hope this helps and wasn't too confusing.
Curious why you want to connect a BH to 3pt instead of a subframe.

Thanks Dog, great pictures. One of my questions to the dealer was did i need to buy/get any NH parts for the power beyond connection and he said NO.
So the manifold you show in your first 2 pics(that I don't have) would not be needed and hte kit is about $500 from NH.

He maded it sound like you just tap into the FEL lines somewhere. Said a service tech could walk me through it.

yes those pictures are worth $100k

thanks

here's a picture on my port inside the rear tire

I didn't want to have to remove the 3pt connections everytime I put the BH on, and I wanted to spend less time switching from bushog to BH.

sound reasonable?

Gary,

It looks like your cover plate at the right rear manifold doesn't have any fittings on it, just attaching bolts. In that case, I think you'd have to run both of your BH hoses forward and just match up the QC's with where you removed your FEL hose. I'd trust your dealer to make sure for you.

I'd be concerned about the stability of your BH mounted on your 3pt hitch vs mounting it on a subframe. I know that some subframe kits are not compatible with mid mount attachments or the new cab versions of the 40 & 45's, so in that case you wouldn't have a choice until someone designs compatible subframes. You want your BH to be as solid as possible and 3pt attachments give alot more than the 4pt subframe attachments. As far as removing the 3pt arms, it's not that big of a deal. I remove my top link and the stablizers for the lower arms and just bungy cord the lower arms together. You could remove the lower arms as well with just a couple of pin pulls if you prefer. It's not that hard once you do it.


lower arms bungied together

you have a plug on your cover plate that can be removed (it is a allen) and that is where you run your return line from the backhoe to the tractor.
I have found that it is easyer and cheaper to install the woods hyd kit (lists for $280) then making hoses and then buying all of the fittings and the time to put it all together. I usally even use the woods kits for almost any backhoe that i sell!
ps it makes it faster and nicer to hook up the backhoe no crawling on the ground and running a line up front and trying not to catch it on a limb and tearing it off!
I hope this helps
