Abstract: A trenching apparatus (100) comprises a main body portion (10), trench cutting equipment (50) depending from the main body portion, at least two ground contacting units (16) arranged on opposed sides of the main body portion and on which the main body portion is supported, each said ground contacting unit being connected to the main body portion by a respective independently operable suspension assembly (20), the respective suspension assemblies being configured to compensate for unevenness of the ground thereby to maintain the trench cutting equipment in a desired angular orientation with respect to the vertical. A method of forming a trench which can use the trenching apparatus is also disclosed.
