Abstract
A lift linkage assembly for a work machine having a work tool. The lift linkage assembly includes a frame, a boom arm, an upper link, a lower link, and a hydraulic actuator. The boom arm is configured to be pivotally coupled to the work tool and has a surface that defines a longitudinal axis. The upper link has a first end pivotally coupled to the frame and a second end pivotally coupled to the boom arm. The lower link has a first end pivotally coupled to the frame and a second end pivotally coupled to the boom arm. The hydraulic actuator has a rod that is pivotally coupled to the boom arm and moves between a retracted position and an extended position. The upper link, lower link, and hydraulic actuator are each spaced from the longitudinal axis.
