Power machines, power sources for power machines, and methods which provide a hydraulic signal from a hydraulic system, through the swivel joint or swivel, to control a tensioning cylinder coupled to the undercarriage without requiring a modification to the swivel. In exemplary embodiments, the same hydraulic signal provided to at least one other hydraulic component on the undercarriage to control another machine function is also provided to control one or more tensioning cylinders. For example, exemplary disclosed embodiments provide the same hydraulic signal to tension a tensioning cylinder as is provided to shift one or more two-speed drive motors. This prevents or reduces the likelihood of de-tracking without requiring a change or redesign of the swivel.
