I have a bradco 509 backhoe attachment, just put it on and connected the hydraulic lines now how do I make the backhoe work? I know with my auger and grapple I move the right joystick 90degrees left or right but is there a switch or button to get constant oil pressure to operate the backhoe?! I know the right joystick on my machine has 3 buttons. One has arrows on top and bottom pointing left or right...tried that...nothing happened. The other button has a icon resembling a shock absorber...pushed that...again nothing and the other button was no use either. I'm 6k deep into this debacle...sure could use some help and/or suggestions...other than go buy a bobcat! Thank you
