Description
The link group is driven by the sprocket and final drive, supports the weight of the machine, provides a rail for the machine to travel on, and provides attachment points for the track shoes.
Features
Grease Lubricated Track has internal lubricated pins and bushings that avoid contact and friction, and each track joint is well sealed to retain the grease. Compared with sealed track, this extends internal wear life by 25%, reduces undercarriage noise, and reduces the likelihood of joints freezing or seizing.
