Have a ZD326 that last week it runs rough and stalls out when we engage the blades. I figured that it was due for fuel filter replacement. Now I'm still getting my feet wet when it comes to working on diesels but after changing the filters I'm not getting fuel back into the filter canisters. I figure that I have to bleed the system out but not sure if there is a bleeder screw anywhere to take care of this.

Did you close the fuel valve when you changed the filters, then forget to open it when you were done?

Try loosening the fittings going from the Tank into the Filters and see if you have fuel flow. Then open the line going OUT of the filter to the Injection Pump and see if you can get fuel going out of the filter. Might try putting a little positive air pressure, a few pounds on the tank and with the lines open see if fuel flows then. Sounds like air lock not letting fuel flow. Once you get fuel into the injection pump it should fire up. Hope this helps.

You need to follow the Kubota fuel bleeding procedure. This is a good thread that thoroughly explains it for you. Be systematic and bleed the injector system sequentially as indicated and it will be free of air and back on track.
