I have a 2012 case sr200 with only 366 hours on it and its never had anything hooked to the aux hydraulics until yesterday. when I hooked up the attachment and used the roller switch on the right joystick nothing would happen, fluid dripped out of the couplers after unhooking so I know the fluid is there but don't know what's wrong. really trying to figure out the problem and would greatly appreciate any advise! where and what do I need to check? thanks!
