309-1281 Idler Group
Heavy Duty Idler Assembly
Description
Idlers guide the track into and out of the track rollers. They intermittently support the weight of the machine and control track slack and tension.
Features
Center tread idlers run on the bushings rather than on the track link rails. They can only be used on SystemOne™ and rotating-bushing tracks, where the bushings can rotate.
