Abstract
An apparatus for excavating a trench in ground comprises two blades (4) which are laterally spaced apart and which are arranged to form two slits in the ground as the apparatus moves over the ground (7). Two laterally spaced excavating elements (9), which are preferably rotatable discs resiliently biased towards each other, are arranged one behind each blade run in the cut of the preceding blade and are operable to grip spoil between the cuts and remove the spoil to form the trench.
