  • Designed specifically to complement Cat machines.
  • Improves machine performance through longer wear life and maintaining traction.
  • Five wheel and tip configurations are available to meet your particular application:
    1) Paddle Tip – High performance and less fuel burn with more traction and less weight.
    2) Plus Tip – Traditional design for increased side slope stability.
    3) Combination Tip – Both paddle and plus tips provide the best compromise of performance and fuel economy with side slope stability.
    4) Diamond Tip – Longest life tip on the market with reputation of reliability that is world class in the waste tip industry.
    5) Chopper Tip – These types of tips are recommended for wet/soft waste where chopping and/or traction is a large concern and abrasive wear life is not a major concern.
