Abstract

A work machine includes a machine body. The work machine also includes an undercarriage assembly having a frame assembly which supports the machine body. The frame assembly has (i) a first frame member, (ii) a second frame member which is movable relative to the first frame member, and (iii) a fluid cylinder for moving the first frame member relative to the second frame member. The work machine further includes a sensor for sensing position of the first frame member relative to the second frame member. Moreover, the work machine includes a controller which is electrically coupled to the sensor. The controller is configured to (i) communicate with the sensor so as to determine the position of the first frame member relative to the second frame member, and (ii) operate the fluid cylinder so as to move the first frame member relative to the second frame member based on the position of the first frame member relative to the second frame member. A method of tensioning a drive track chain is also disclosed.
