A portable leaf blower comprises a blower tube, comprising an adjustable nozzle portion (200) which is reconfigurable between an air speed mode, in which the nozzle portion (200) is configured to expel the air from the blower at a relatively higher air speed and a relatively lower volumetric flow rate, and an air volume mode, in which the nozzle portion (200) is configured to expel the air from the blower at a relatively lower air speed.
