A bush-cutter for the manual moving of grass and the like comprises a rod or a stiff arm, working as a handle, which supports at one end a cutting head rotating around on axis and having cutting means with a cutting element, for example a blade or a flexible rope or the like, and engine means which make the cutting head rotate through gearing means. According to the invention, the bush-cutter comprises spacing means (13), including a spacer (14) which swings coaxially to said cutting head (11) around said axis (X-X) and which, during the mowing of the grass, selectively contacts any possible obstacle at a radial distance from the cutting head (11), that is longer than the radial extension of the cutting element of said cutting means (11.2), in respect of the head, in order to avoid the contact of said cutting element with the obstacle. |
