4740 GST Power Beyond

jwbrown · Dec 15, 2008

I have a 4740 GST. Currently, I have dual rear remotes on the tractor. I am building a winch that I plan to use on it. The winch it'self is a mechanical PTO operated.

To engage and disengage the winch, I plan to use a open center motor sppol valve and a double acting cylinder. The reason is because I need the valve to spring back to neutral when released and not hold a load. If it did hold the load, the winch would keep turning when the valve is relased. I have looked at the remote valves on my tractor. I know that they are not made by Kubota even though I had them installed ion my tractor by the dealership when I bought it. Does anyone know the brand? If I knew that, I could possibley find a stack valve that would bilt to the 2nd remote valve. My other option is to add a power beyond and another valve. Does anyone know if there is a power beyond port on the rear remote that I can plug into? If so, what type of adapter do I need?

To my knowledge, all the Kubota OEM valves are made by Husco-but they will not talk to you, they will just refer you to your dealer. Not sure if that have a PB plug-you have to look at that...But if you can get tto the OUT line easily, you can just plumb a new valve in series with that and not worry about the PB.

If the hydraulics are similar to my L3130 you could take the power beyond off the loader valve before it goes to the 3point. Have a hookup for a backhoe with 3 connections and a hose that is looped to power 3 point hitch and I would suspect the factory remotes if they were installed when backhoe is not mounted. On the factory remotes I know you can get regular spool and one with float not sure if you could find another one to swap out setup for motor though.
