Abstract
An excavating apparatus for excavating a ditch in the ground, the apparatus including a vehicle (2) and a cutter (22), the cutter being attached slidably to upper and lower horizontal guides (7,8) mounted on the vehicle, and having upper and lower hydraulic cylinders (16,18) to move the cutter (22) relative to the upper and lower horizontal guides (7,8). If the angle of the cutter (22) inclines from the vertical it can be corrected by use of the upper and lower hydraulic cylinders (16,18). During the excavation of a ditch the cutter (22) is driven forward by the hydraulic cylinders (16,18) with the vehicle (2) stationary with the result that an accurate ditch can be excavated.
