Key components such as track rollers, idlers, sprockets, and track shoes are forged from through-hardened boron steel alloys, providing exceptional strength and wear resistance. The staggered roller design reduces vibration and improves ride comfort, while deep heat treatment processes on rollers and track links prevent loosening of pins and bushings, ensuring longer, more uniform wear
The Undercarriage Parts for John Deere Dozers are engineered to deliver superior durability, performance, and cost efficiency for heavy-duty earthmoving operations. John Deere offers three main undercarriage systems designed to meet varying operational needs:
Heavy Duty Undercarriage: Provides a solid baseline with components matched in tolerance, strength, hardness, and wear limits, offering about 2,000 hours of life with standard sealed and lubed track.
Extended Life Undercarriage: Features SC-2™ coated bushings that significantly enhance wear resistance, extending track chain life to approximately 3,000 hours and reducing operating costs by around 29%.
Maximum Life Undercarriage: Combines SC-2 coated bushings with stronger seals and larger components for the best abrasion and impact resistance, delivering up to 4,500 hours of life and up to 57% cost savings compared to standard systems
