High-Speed Trencher Head, Compact Tool Carrier

Toro High-Torque Trencher Head, Compact Tool Carrier is an attachment designed to dig trenches in soil for laying cables and pipes, and is not suitable for cutting hard materials like wood or concrete. It features a digging chain and auger that can be offset from the center of the machine to dig trenches close to structures. It can be installed on a Toro tool carrier with a variety of booms and chains. The trencher head can be flipped upside down to expose a second set of teeth for double the life and can be easily transported by folding it close to the ground.
