  • Publication number: 20100077621
    Abstract: The present invention relates to a vegetation cutting tool. In particular, the present invention relates to a powered vegetation cutting tool and more particularly to a linkage mechanism for a powered vegetation cutting tool. We describe a vegetation cutting tool comprising a cutting head, a motor and transmission means drivable by the motor. The cutting head includes first and second cutter members having respective cutting surfaces, wherein the first cutter member is pivotably mounted with respect to the second cutter member. Additionally, at least the first cutter member is drivable by the transmission means between a first angular position with respect to the second cutter member, in which a space is formed between the respective cutting surfaces, and a second angular position with respect to the second cutter member, in which the space between the respective cutting surfaces is closed.

  • Publication number: 20100071218
    Abstract: The present invention relates to a switch-operating mechanism. In particular, the present invention relates to a switch-operating mechanism for a power tool, such as a pruning tool. Described is a switch-operating mechanism for a powered tool including a working head having first and second cutter members. The switch-operating mechanism further includes a lever moveable between first, second, and third operative positions. In operation, positioning of the lever in the first operative position provides a ‘power off mode’ in which the power supply is disconnected; movement of the lever into the second operative position causes the at least one of the cutter members to move to a first blade position; and movement of the lever into the third operative position causes the at least one of the cutter members to move to a second blade position.
