Dozer D65 18 WH 1

When dealing with challenging waste conditions, you need top-notch equipment. Our dozer waste solutions are crafted based on field experience and customer feedback, ensuring they provide robust pushing power and come equipped with special filters and guards for protection against environmental debris.

  • Designed to safeguard essential machine parts
  • Enhanced protection from airborne debris
  • Decreased wear on components

Product Features and benefits:

  • Auto Reversing Fan: Minimize overheating caused by airborne debris with a fan that automatically reverses based on an adjustable interval and duration.
  • Engine Pre-Cleaner: Ensure a clear engine by using a pre-cleaner that blocks and removes large particles from the air before they reach the engine air filter.
  • Extra Guards Throughout: Safeguard your machine against damage and contamination from debris with additional guards added to final drive seals, tanks, and the engine.
  • Track Shoe Holes: Reduce track compacting by allowing debris to be pushed through the track shoe holes.
  • Re-Located A/C Condenser: Improve cooling efficiency with a re-located A/C condenser mounted on the roof to protect it from debris.
  • Trash Rack: Enhance operator visibility during waste movement with a trash rack designed for optimal visibility and increased blade capacity.
  • Front and Rear Striker Bars: Prevent debris from riding up on the tracks and damaging the chassis with front and rear striker bars.
