Hi All, I just got a Bobcat 763. All seems great with it. However, I want to use a post hole auget with it and have no idea how to use the secondary hydraulics. i.e. I know to move the steering lever to the outside to activate, but what about connecting.disconnecting the auger. What is the procedure I should follow? I read somthing about depressurizing the system, to remove the attachment, how do you do that? Thanks in advance
