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.

Abstract: A mini-excavator includes a base supported by first and second track assemblies on which the vehicle travels. The base supports an operator support, which includes first and second travel control devices, such as travel levers. Each of first and second closed-loop hydrostatic systems of the mini-excavator are coupled between different ones of the travel control devices and the track assemblies to control the speed and direction of travel of the track assemblies. Each of the closed-loop hydrostatic systems includes a closed-loop travel motor and a closed-loop pump coupled directly to the closed-loop travel motor.
