    Default Power Beyond

    Hello all,

    I'm getting ready to hookup my Bradco 609 backhoe on my kubota 3710 and need a little help with some hydraulic plumbing. The feed line for the hoe is suppose to come from the "Power Beyond" at the FEL control valve. I'm not sure if I have one of these. I've looked in the manuals for the FEL and tractor and can't find any mention of this. I did a search here on TBN and I get the impression that this is a add on option.
    Anyone out there that can point me to some information or pictures on this feature would be great.
    Anyone that has a Bradco 609 on a Kubota I like to hear how the plumbing was done on your tractor.

    Thanks,

    Jim

    Jim, the Power Beyond port is usually labelled "PB" on the loader valve. In addition to the 4 hoses going to and from the loader, you should have one hose from the tractor hydraulics outlet block to the valve, the Power Beyond hose going back to the outlet block, and the outlet hose from the loader valve going to the tank or reservoir. I think (can't say for sure) that all the later model kubota loader valves have the Power Beyond.

    Thanks Bird,

    I have a 1999 kubota LA681 FEL on the tractor. I will take a closer look at the valve when I get home from work tonight.

    Thanks,

    Jim

    Jim - Check out <A target="_blank" HREF=http://www.tractorbynet.com/cgi-bin/compact/showthreaded.pl?Cat=&amp;Board=custom&amp;Number=2 2293&amp;page=&amp;view=&amp;sb=&amp;o=&amp;fpart= 12&amp;vc=1>this post</A>, which describes the way I did it the third and final time I plumbed a Bradco 609 on a kubota L-series. As I said, I've done it three times, and this was the best way, by far. A lot easier to use, more flow, safer, faster to connect and disconnect, you name it.

    Mark,
    I read through &lt;most&gt; [img]/w3tcompact/icons/smile.gif[/img] of that thread. I found where you said the name and manufacturer (Compact CP528-2-B-6S-12DS) of your solenoids. How did you know where to find them; who did you speak to about them before buying them; can they still be purchased wherever you got them?

    Mark - Compact is a very well known brand of industrial-control hydrualic valve. I talked to a guy at a hydraulics shop in Richmond, VA, and ended up buying them through him. They're available pretty much every place that carries industrial hydraulics. The ag hydrualic valves I found were just too big to fit or too cheesy to suit me. If you want those valves specifically, I'd just look in the Yellow Pages under Hydraulics and call the folks listed. If you want me to give you the name of the guy in Richmond that I buy my stuff from, I can e-mail it to you. Just let me know what you need.

    Thanks for the help Bird, I was able to find the "PB" on the valve block. In the loader manual they call this line the "Carry Over port". Half of the problem is trying to figure out the terminology that each person uses for the same part. Things are becoming much clearer now.

    Thanks again,

    Jim

    MChalkley, I've drew out what I think your hookup looks like with the two "T"s and valve. Is this correct?

    Jim - Precisely. Nice job! A picture is truly worth 1,000 words, in this case. Or, several hundred, anyway. [img]/w3tcompact/icons/wink.gif[/img]

    Jim - Let me belabor a point. It doesn't matter which pressure line you tap into if you do it this way. You can use a designated PB line, or you can use the main line coming from the pump, after it leaves the block. In my case, I wanted as much flow as possible, so I tapped into the circuit immediately after it leaves the front block, and before it goes through the FEL valve. You wouldn't want to put the tee in the line from the pump to the block, because the relief valve is in the block, and if you were to close the valve without the backhoe hooked up, you would burn up the pump.
