Industrial 304 with 220 backhoe attachment

dajain · Dec 27, 2015

I'm looking to replace the valve bank on my MF backhoe and after many searches, I can't find the answer I am looking for. Maybe you guys can provide the answer I seek.

Simple question:
What is the GPM flow of the hydraulic system for this backhoe?

Thanks for any and all replies!

Thanks for the info, but I am considering upgrading to a twin stick system. But I don't want to order one that is undersized and have it fail or pay for more than I need. I have a couple valves picked out, but just need to know what volume this 220 backhoe pump puts out.

Thanks for the response!

OK, broke out the service manual and finally found the rated GPM for this tractor/loader/backhoe assembly.

The book says 22 GPM at the pump, so would estimating 11 gpm per function be a good guess?

There is no diversion valve to choose either function. They both see flow 100% of the time
