I’m new to the forum and need some help.
I recently bought a 2019 L4060hst with a front loader and a 3rd function installed.
I am having trouble figuring out how to plumb the hydraulic lines for the backhoe. Any/all help is greatly appreciated!
Thanks, Greg.

There should be a couple of hoses connected together making a complete loop. One hose will have a male end and the other will be female so it is possible for them to be connected.

The backhoe should have connection points to match the hoses and supply flow to and from the backhoe valve.

I am assuming that the backhoe was already installed on the tractor before and you are not adding it as “new”.

Thank you for your reply!
Yes, the backhoe was on a different model Kubota.
My used Kubota L4060 has a 3rd function added to it. It looks to me like the 3rd function hydraulics connect below the driver seat. I was wondering if I can add a couple of tees to those lines to use as the hydraulic feed and return for the hoe. That would be before the solenoid that activates the 3rd function.
What do you think??

No. You supply ths backhoe from the pressure return port on the third function valve. Post a picture of the third function valve connections so we know what you currently have.
