Description
The link assembly is driven by the sprocket and final drive. It supports the weight of the machine, provides a rail for the machine to travel on, and provides a place for the track shoes to attach.
Features
Grease lubricated tracks have internally lubricated pins and bushings to avoid contact and friction, and each track joint is sealed to keep the grease in. As a result, the internal wear life of sealed tracks is extended by 25%, undercarriage noise is reduced, and the chance of joints freezing or seizing is lowered.
