Why no "Power Beyond" for Kubota tractor?

[murphy1244]

So run the 2nd hose at the back of the tractor fill port by removing the quick disconnect - right?

yes sir----also A flow loop is a section of hose that connects the 2 ports together so you can't deadhead.

I used my wife as a "bungee cord" and what happens is the backhow freezes and to unfreeze it I need her to retract the valve in the reverse direction then back to the other direction so the bungee lock would not work. I'm thinking there needs to be some dort of relief that the current valves don't have( which is the Kubota valve kit)

CONFUSED

Cat driver,
If connecting to your rear remotes you MUST connect one of the hoses to pressure port of the back hoe valve and the other port of the remote must connect to the tank port of your back hoe. It is VERY, VERY important to be 110% sure that when you operate your remote directional valve that the port being pressurized is ALWAYS the line connected to pressure port of the back hoe. If you reverse these connections there is very good chance that you will damage the back hoe valve.

You don't need to run the backhoe off a remote valve. Just plumb the backhoe inline in the power beyond loop, after the front loader and before the three point hitch (I'd put it after the remote valves).

If it's a Kubota backhoe, it's meant to plumb into the power beyond loop with hoses. When you attache the backhoe, the hoses connect to it. When you remove the backhoe, the hoses connect together to maintain the power beyond loop.

Don't make it more complicated than it needs to be.

I just called Messics and they have no power beyond for Kubota tractor OEM.
I want to connect a Backhoe and Trencher to a L4060 HST cab.

Sales said they have a "FLOAT" valve but no "POWER BEYOND"
It's my undertsanding that one needs a power beyond valve detent to
run a backhoe?

Also, your terminology is really mixed up, which isn't helping you or anyone else. Some valves are float, some are double acting, some have detent. Power beyond isn't a valve type, it's the hydraulic circuit itself. All the valves run off power beyond.

:thumbsup:
That is the way my Kubota BH92 backhoe is plumbed on my L5060.

I found this....I think this is what you mean

 

[Cat_Driver]

I found this in the manual so it goes AGAINST all the bungee talk....


A Do not hold the lever in the "REARWARD" or "FORWARD" position once the remote cylinder has reached the end of the stroke, as this will cause oil to flow through the relief valve. Forcing oil through the relief valve for extended periods will overheat the oil.
A Whenusingthetractorhydraulicsystemtopowerfront loader, do not operate boom and bucket cylinders simultaneously.

There in lies my problem - the lingo.
All of these term were unheard of until yesterday, so honestly I wouldn't know a power beyond if it tappen me on the shoulder.

I guess I'm finding it can be either plumbed direct from power beyong port. OR through a valve that allows flow through?

Thank you sir - even more scared now than ever to even touch this thing.
I wante dto avoid the dealer as they are 50 miles away, but all this seems WAY WAY WAY over my head.

Are you getting a Kubota BH made for your L? Trying to adapt an aftermarket BH could present problems. The L are designed to accept their companion BH. The operating valve for the BH is self contained and as was explained by S219 and Oldoak there are 3 connection points somewhere in the rear; Power (P) Tank (T) and Power Beyond (PB). Using a bungee cord is nonsense and a work around probably from guys that do not understand hydraulics like you. Just be sure; if you buy some after market BH that it has a PB valve setup on the BH. I have seen those 3 point hitch BHs but have no clue how they operate. That may be what folks are trying to do with the bungee instead of doing it right. The trencher presents the same problem as the BH. Once you get the P, T, PB connections figured out then the trencher must also have the 3 connections. Now you are getting into new valve subject; hydraulic motors need a valve made specifically for motors. I built a wood splitter and set it up the same as my BH, it had it's own operating valves.

If you really want to understand the hydraulics of your L get the Workshop Manual from your dealer or Messicks. If you are not mechanically minded you may never figure it out.

Probably time to at least visit your dealer and discuss what you have and what you want to do. Don't confuse your discussion with improper terminology when you do that. Let him explain. Maybe one of our hydraulic experts lives close to you and will make a site visit.
