The trench cutting machine comprises a frame (12) comprising at least one rear axle (15) and at least one front axle (17); a rotatable circular blade (20) mounted to the frame (12). The front axle (17) is vertically adjustable relative to the frame (12) between a first position where the circular blade (20) is lifted clear of the surface (13), and a second position where the circular blade (20) is arranged to extend downwards from the frame (12) to cut a predetermined distance into the surface (13). The frame (12) comprises an auxiliary front axle (19) located in front of the axis of rotation of the circular blade (20), wherein the auxiliary front axle (19) and the rear axle (15) are arranged to support the frame (12) on the surface (13) during a cutting operation and to maintain a selected depth of cut. The invention further relates to a shroud assembly and a debris guiding device for such a machine.
