How to Add a Free Flow Return Line on a Kubota B2100

[xenophon.nl]

I'm looking for some advice on adding a free flow return line to my Kubota B2100 tractor. I'm planning to use a hydraulic conveyor belt. I've attached a diagram of the hydraulic system.

Are there any spare ports or external points I could use to add a return line?

The filler port has no threads, so I’d prefer a permanent setup and am unsure how to properly seal it against water or dirt if used.

Thanks in advance for any help or insights!

How are you supplyimg the conveyor? The reason I ask is at a minimum its going to render the 3pt inoperable.

There is a tank return port on the side of the hydraulic case that is used by the loader. You can replace fitting #40 with a tee and add a quick coupler for the conveyor return line.

Thank you, that sounds like a plan!

Do you maybe know what type/size fitting it is?

The conveyor belt is for a shredder, the PTO will be running, but no other functions are necessary at that moment. I have a single acting output in the back that I was planning to use, It is an original connection with a lever in the cabin that you can 'hook'.

I am guessing but with 90% plus confidence the tank port is BSPP (G thread). ,Probably 3/8" with a little less confidence.
