A tracked vehicle, in particular a construction machine, more particularly a road construction machine, with at least one drive motor and a travel pump of a travel drive hydraulic circuit, which is driven by the drive motor, for generating a drive pressure; at least one track unit, said track unit comprising a drive wheel driven via the travel drive hydraulic circuit, at least one guide wheel, a track endlessly running around the drive wheel and the guide wheel, as well as a track tensioning apparatus for tensioning the track, and the track tensioning apparatus comprising an adjusting device with a track tensioning hydraulic cylinder with which the distance between two wheels of the track unit, in particular the drive wheel and the guide wheel, is adjustable for tensioning the track, the track tensioning hydraulic cylinder being connected via a hydraulic tensioning line to a hydraulic pretensioning source via which it can be loaded with an initial pretensioning pressure. The tensioning apparatus further has a damping device with a spring for damping pressure peaks in the adjusting device. A method for operating a tracked vehicle with a track unit.
