Yeah. I'm finding out that the 709 main mounting pins are not able to reach far enough rearward to engage into the backhoe brackets. I was assuming all backhoe attachments work easily interchange, but seems as if the 709 is designed for the 700 series machines & 811 attachments are designed to work with the 800 series machines.Pretty sure it will, the only thing you will need to work on is the mounting brackets to suit your machine
