John Deere 310se Auxiliary

Hello, all:



I just bought this 2000 John Deere 310SE backhoe with the extendahoe and I am starting to do a little digging into it. I attached a JRB quick coupler attachment on the loader and hooked it up to the auxiliary ports that were on the machine. When trying to engage the cylinders on the coupler to lock in the pins on a bucket, nothing happens. I can see the hoses jumping with pressure when I actuate the auxiliary pedal, but no action.

I am not all that familiar with John Deere and this is my first time having a backhoe with auxiliary ports, so maybe I'm just doing something wrong.



Does anyone have any suggestions? What could I be doing wrong?



Thanks in advance for any advice!
