Trenchers are machines used to dig trenches in the ground for various purposes, such as installing cables, pipes, or drainage systems, and can be used for digging trenches for landscaping or construction projects. Trenchers have a digging attachment that is lowered into the ground to excavate a trench and are typically powered by a gasoline or diesel engine and can be operated by one person.
