Trencher (machine) : ウィキペディア英語版 | Trencher (machine)
A trencher is a piece of construction equipment used to dig trenches, especially for laying pipes or cables, for installing drainage, or in preparation for trench warfare. Trenchers may range in size from walk-behind models, to attachments for a skid loader or tractor, to very heavy tracked heavy equipment. ==Types== Trenchers come in different sizes and may use different digging implements, depending on the required width and depth of the trench and the hardness of the surface to be cut. Trenchers must be handled with extreme care because they are very dangerous equipment.
