Features

  • General duty tracks are designed to be a cost-effective option for machines nearing retirement or with low utilization. Their lower initial price allows them to be run until failure. All Cat® undercarriage systems are backed by the Undercarriage System Guarantee. Manufactured by Caterpillar, they are hardened and quality tested to meet the productivity and performance demands of the job site.
  • Cat® Sealed and Lubricated Track (SALT) seals lubricant inside the undercarriage system and keeps abrasives out. It eliminates internal pin and bushing wear, reducing maintenance costs and downtime while extending service life and improving serviceability. Combined with a track design matched to your machine and work environment, SALT provides a versatile undercarriage configuration for a wide range of ground conditions.
