kUBOTA 4540 A air into hydraulics on backhoe

[ecm2004]

I have a Kubota 4540A tractor with A Backhoe and within 10 minutes of useing backhoe the hydraulic sytem starts to foam and will not work.
It has to sit for a while before I can use again!!
Any suggestions would be appreciated !!
Thanks

Is the tractor fluid full?
Also has it been working fine before?

Yes Fluids are full and It was working fine! I have not had the tractor that long!
Thanks

With fluids full and aeration happening, I would start with filter and pickup screens and connectors to see if air is leaking in. Hope the pump does not have a leak. Its doesn't happen right away, only after it heats up and things expand

Have you posted this on orangetractortalk.com ?

No I have not!! I will check out the filter and pick up screen and go from there!! Thanks for the response..
