Abstract
An interface between a hydraulic power system and an hydraulically actuated engagement member includes a first portion that is pivotally coupled to a second portion, and has an inlet capable of being coupled to the power system. The second portion is fixedly attached to an attachment bracket capable of interfacing with an attachment. The first portion has a path to provide oil to the second portion, which in turn provides oil from the first portion to the attachment bracket. The attachment bracket includes a housing that accepts an engagement member capable of being hydraulically actuated to secure or release the attachment with respect to the power machine.
