ABSTRACT:
A hydraulic track tensioning circuit is connected to an idler wheel of a track drive mechanism to maintain a tension in a track proportional to the drawbar pull of the track drive mechanism. The tensioning circuit includes a variable pressure relief valve having a variable pressure setting controller which controls the tensioning pressure in a supply line connected to a hydraulic tensioning cylinder in response to the highest pressure in a pair of motor ports of a reversible hydraulic drive motor operative to propel the track drive mechanism.
