ABSTRACT:
An endless track assembly for use with a track-type vehicle having a notched drive sprocket is provided with link elements having a resilient mid-pitch impact lug located midway between the track link bushings. The resilient mid-pitch lug reduces track noise and wear due to metal-to-metal impact of the track against the sprocket and idler by having a topmost portion of greater height than adjacent bushings whereby initial contact is made by the lug so that impact energy is thereby absorbed prior to engagement of the track bushings.
