A flow-through brush cutter is mounted on a tracked vechicle and includes a thin, flat blade having a replaceable V-shaped forward cutting edge and adapted for movement along a horizontal plane disposed beneath the surface of the earth. A pair of thin legs extend upwardly from spaced points on the blade and are connected to the track assemblies of the vehicle by a pair of forwardly extending arms. The horizontal positioning of the blade is controlled by a fluid-powered cylinder mounted on a subframe secured to the frame of the vehicle and a cable system actuated by the fluid-powered cylinder and connected to the arms. Lateral displacement of the blade is controlled by guide members extending on opposite sides of the arms and secured to the track assemblies of the vehicle and to the subframe. The guide members are secured to the subframe by means of pin and slot connections which accommodate relative movement between the frame and the track assemblies of the vehicle.
