I have an ASV RC60 skid steer. This problem does not effect the loader or drive line hydraulics, only the attachment hyd. There is a fuse labeled "AUX HYD MO" that blown so I replaced it. It seemed to be about 20 mins and blown again. Replaced it right a way and the new one blew as soon as I plugged it in. Left it. Days later I put in a new fuse and all works. About 20 mins later, blown. Days later, replaced it and just left the skid steer idiling and kept testing every few mins. Somewhere between 20 and 24 mins the fuse blew. Does anyone have any idea? Does anyone know what this fuse feeds? Any help would be greatly appreciated.
