Abstract
A tensioning device is provided for maintaining the tension on a continuous flexible track of a track apparatus. The track apparatus includes an idler wheel which engages the flexible track and which is movable between a first non-deflected position and a second deflected position. A dampening mechanism extends between an idler axle which supports the idler wheel and the frame of the track apparatus in order to exert a force on the idler axle to urge the idler wheel towards the non-deflected position. The dampening mechanism progressively increases the force on the idler axle as the idler wheel moves towards the deflected position.
