2058291 9114363 PCTABS00007 A weed-killing device has an elongate hollow handle (10) having a hollow body (11) adjustably mounted on one end, the body having electric heating elements therewithin and an outlet nozzle (12). A chamber (17) is provided part-way along the handle (10) and an electric motor driven fan unit (16) is arranged to draw air into the chamber (17) and drive the air along the handle, through coupling (19), over the heating elements and out of the nozzle (12). Hand grips (21 and 22) are provided for ease of use. An internal combustion engine driving a fan and an electric generator may be provided within the chamber (17) instead of the electric motor driven fan unit, waste heat from the motor then serving to pre-heat the air. Different nozzles may be provided to allow destruction of weeds by the hot air blast, without harming immediately adjacent plants.
