ABSTRACT:
A circular cutter wheel (34) is mounted on a work head housing (24) to rotate about a vertical axis (Y). A chain saw (76) is mounted on the housing (24) above the wheel (34). The saw (76) is mounted by a swivel device (42) which continuously rotates the saw (76) about a vertical axis (X) between a nonuse position in which the saw (76) extends over the housing (24) and a plurality of use positions in which it projects forwardly and/or laterally therefrom. The device (42) includes coaxial cylindrical housings (44, 48). The saw (76) is secured to an outer circumferential surface (82) of the outer housing (48). A motor (50) carried by the inner housing (44) rotates the outer housing (48) and saw (76).
