isn't that the same valve as posted above? i don't see where the 3rd hose goes. what does the 3rd hose do anyway? any help is appreciated.

thanks

You have 3 hoses to the tractor. One is high pressure coming from the pump, another is the high pressure return from the power beyond which feeds the 3 point lift. The final is the lower pressure return for the oil used by the valve.

In port------Pump flow, high presure
Tank port---low pressure , goes to tank
PB port-----downstream fluid flow for use by other valves.

Work ports = 4

thanks. that explains a lot.

so that means i need the power beyond kit as well right?

do any of you know which is which on my original valve? i have 2 that look like they come from close to the engine (i assume this is where the hydraulic pump is), and one the goes to the back of the tractor to i guess that's either the tank or the 3pt. will it kill anything if i hook it up wrong while trying to figure out what goes where?

thanks again for all the help, i've almost got it all figured out.

Yes, you wll need the kit or adapter.

If the PB port has a plug in it now, you will need the adapter sleeve or the hex screw to make that port a PB port.

After you install the PB adapter, connect a hose from the PB outlet to the 3pt line, and route the tank port to tank.

thanks, i got it.

i just got back from the kubota dealer, and they told me which line is which. so now all i have to do is buy the valve, buy the adapter, buy 3 new hoses the right length with the right fittings, weld up a 90 deg plate to mount the new valve on, and jerry rig an adapter for my old control lever. no problem.:thumbsup:

thanks again for your help.

This is the PB sleeve for the valve that I posted above.
