A boom type trenching machines for mounting on a tractor to form a trench in a surface. The trenching machine has a main body 22 for attachment to a tractor and a trenching boom 12 having an endless excavator chain extending around a pair of sprockets 14, 16 and configured to move vertically with respect to the main body. The trenching machine has an auger assembly 60 including an auger 62 driven by the excavator chain to rotate and move spoil dug by the chain away from the trench. The auger assembly is moveably mounted on the boom such that as the boom moves vertically into and out of the trench, within a range of vertical positions, the auger maintains a constant position relative to the surface 11. Optionally, the auger assembly is slidably mounted on the boom. Optionally, the auger assembly comprises a carriage that is slidably mounted to the boom, the auger being rotatably mounted to the carriage. Optionally, biasing means to urge the auger assembly downwards are provided, having a hydraulic piston operatively linked to the auger assembly.
