A boom type trenching machine for mounting on a tractor. The trenching machine has a main body (figure 1, 22) for attachment to a tractor and a trenching boom 12 having an endless excavator chain 20 extending around a pair of sprockets 14, 16 and configured to move vertically with respect to the main body. An elongate crumber bar 38 connected adjacent to the trenching boom, extending generally parallel thereto along a trailing edge and configured to move vertically with the boom. Crumber bar mounting means (figure 1, 36) are adapted to connect the crumber bar to the boom and permit selective linear vertical movement of the crumber bar relative to the boom. Optionally, crumber bar mounting means includes a rack and pinion arrangement, which is driven by a hydraulic motor. Optionally, an auger is provided to move spoil laterally away from the top of a trench formed by the boom.
