When facing the most challenging waste conditions, you need the best equipment. Our dozer waste solutions are crafted based on field experience and valuable customer feedback. They provide robust pushing power and come equipped with special filters and guards designed to offer protection from environmental debris.
- Designed to safeguard vital machine parts
- Enhanced protection from airborne debris
- Reduced wear on components
Product Features and benefits:
Auto Reversing Fan: Minimize overheating caused by airborne debris with a fan that auto-reverses based on adjustable intervals and duration.
Engine Pre-Cleaner: Ensure your engine stays clear with a pre-cleaner that effectively blocks and removes large particles from the air before reaching the engine air filter.
Rear Oil Cooler and Tank Guard: Enhance machine protection from damage and contamination due to debris with extra guards added to final drive seals, tanks, and the engine.
Track Shoe Holes: Reduce track compacting and allow debris to be pushed through track shoe holes for improved performance.
Trash Rack: Optimize operator visibility during waste movement with a specially designed trash rack, offering a wide range of vision and increased blade capacity.
Front and Rear Striker Bars: Prevent debris from riding up on the tracks and causing chassis damage by utilizing front and rear striker bars.
Rear Oil Cooler and Tank Guard: Enhance waste operation efficiency and cooling with a relocated hydraulic cooler at the rear of the machine, maintaining optimal performance.
