Abstract: A tool assembly for engaging a head of a fastener. The tool assembly includes an elongated hollow shaft member having a first end and a second end and an actuation rod member moveably disposed within the shaft member. The actuation rod member includes a first end corresponding with the first end of the shaft member and a second end corresponding with the second end of the shaft member and an expandable tip assembly. One end of the expandable tip assembly is movably coupled to the actuation rod. The other end of the expandable tip assembly includes a patterned face. A first contracted state of the expanded tip assembly allows the patterned face to mate with the head of the fastener, and a second expanded state of the expanded tip assembly allows the patterned face to securely engage the head of the fastener.

Abstract: A lawncare machine 100 has a powered rotary raking or scarifying reel 5 together with a powered vacuum collector 8 whereby material thrown up by the reel is immediately drawn into the collection chamber 8. During removal of the vegetation material, it is drawn into the chamber 8 due to a suction created by a fan 2. The material is normally held in the box by means of a perforated screen 10 situated between the box and fan entry. The chamber 8 may be emptied by moving the screen 10 so that the material is discharged through the fan 2. Alternatively the chamber 8 may be emptied by means of flap valves 19, 21, 23 which cause a reversal of the airflow through the chamber so that the collected material never passes through the fan.
