Extensive guarding minimizes debris buildup and helps keep close encounters with obstacles from slowing you down. And a solid-state electrical-distribution center, durable sealed-switch module, and state-of-the-art diagnostic multifunction monitor further boost uptime and productivity. That's just the beginning of all the ways the 644K WH Waste Handler helps take out the trash.
