A hydraulic tensioning system for a tracked undercarriage is configured to position an idler wheel, supported by a frame assembly, relative to a drive sprocket. The hydraulic tensioning system includes at least one fluid actuator unit with a body that defines a recoil chamber, a tension chamber, and a wall in between the two chambers. A piston assembly is positioned between the body and idler wheel. A ram assembly is positioned between the body and frame assembly. A recoil circuit is in fluid communication with the recoil chamber and a tank. A fluid in the recoil chamber is relieved through a relief valve when the idler wheel is displaced. Fluid is introduced to the recoil chamber, urging the idler wheel away from the frame assembly, via the piston assembly. A tensioning fluid within the tension chamber selectively urges the idler wheel away from the frame assembly, via the ram assembly.
