ABSTRACT:
A track assembly (11) for a track-type vehicle (10) includes a pair of link assemblies (17,18) having inboard links (20,24) thereof solely engageable with the idler (13) and track rollers (14) of the vehicle (10). When the vehicle (10) traverses wet or swampy ground, wherein it proves desirable to utilize relatively wide track shoes (16), torsional loads imposed on the shoes can cause premature wear or damage to the shoes (16). The track assembly (11) exhibits a high resistance to such torsional loads imposed thereon and adapts itself for use in lieu of a standard track assembly on a conventional track-type vehicle. A method for prolonging the service life of the track assembly comprises interchanging the two link assemblies (17,18).
