The invention relates to a device for cutting and weeding the edges of lawns, turf and other herbaceous surfaces. The invention relates to an accessory which can be fitted to a strimmer or other similar devices, allowing the edges of green spaces to be easily maintained. It consists of a conical rotor provided at both ends with two toothed cutting edges (1) and (2) connected by a central shaft (13) and four blade-holders equipped alternately with blades provided with spikes (7) and with flat blades (9). In order to avoid the recoil effects due to the combination of the speed of rotation of the rotor and striking inert material (pebbles, stones or the like), in addition to its conical shape allowing gradual penetration into the soil, this rotor is attached to the shaft (11) of a drive head (6) which is characterised by its low frequency of rotation. A gear-coupling mechanism (figure 5), which reduces the revolutions of the drive shaft of the rotor, ensures that the tool is stable and safe. Likewise, to complete the safety aspect, a counterweight (8) of identical mass to the rotor, attached to the drive shaft opposite the latter, enables perfect balance and control of the apparatus. A housing (3) and a splash guard (4) complete the protective equipment of the tool, while two decorative nuts (5) secure the rotor and the counterweight to the shaft (11) of the drive head.
