A tension management system is provided for an endless track laying work machine. A fluid cylinder maintaining tension within the endless track. A first accumulator provides recoil for normal operating conditions. If tension on the endless track increases beyond a normal recoil situation, fluid is bled off through a pressure relief arrangement to a second accumulator. The system requires an initial fluid charge from a fluid power unit, and is then disconnected and operates as a stand alone system.
