发明名称 Apparatus and method for operating a hydraulic excavator which has a position sensor for sensing position of an idler wheel
摘要 A method of operating a work machine having (i) a drive motor for driving a drive track chain, (ii) a track tensioning assembly for adjusting tension on the drive track chain, and (iii) a work implement for performing a work function includes the step of idling the drive motor so as to cease advancement of the work machine during a first period of time. The method further includes the step of operating the work implement so as to perform the work function during the first period of time. The method also includes the step of operating the track tensioning assembly so as to increase tension on the drive track chain during the first period of time. The method yet further includes the step of actuating the drive motor so as to advance the work machine during a second period of time. Moreover, the method includes the step of operating the track tensioning assembly so as to decrease tension on the drive track chain during the second period of time. A work machine is also disclosed.
