Abstract
A tracked suspension for a tractor or other work vehicle is disclosed having an endless belt, a belt tensioner, a drive wheel, and a plurality of idler wheels mounted to a suspension frame or idler carriage, the assembly being arranged such that the belt tension provided by the tensioner is absorbed within the frame and is not transmitted to the axle extending from the tractor that drives the tracked suspension. The tracked suspension can be adjusted by loosening or removing mounting bolts that fix the suspension to beams extending from the vehicle, sliding the suspension toward or away from the vehicle, and tightening the bolts. By absorbing the belt tensioning forces within the tracked suspension itself, rather than transmitting the belt tensioning forces to the axle, the suspension can be more easily adjusted without requiring the removal and replacement of the drive axle.
