    Idler (Center Tread, Cast)


    • Idlers guide the track in and out of the track rollers. They intermittently support the machine's weight and provide a way to control track slack and tension.


    • Center tread idlers run on the bushing rather than track link rails. They are used exclusively on SystemOne™ and Rotating Bushing Track where the bushing rotates.
