  • Patent number: 4224739
    Abstract: A pruning tool is provided that allows the individual operating the tool to make flush cuts of vegetative growth to stems and branches having a wide range of directions of the extension with respect to the point at which the individual is standing, without moving from that point. The pruning tool includes a cutting head, a pole, and operating mechanism including a cord extending down the pole from the cutting head, and a connection between the cutting head and the pole that allows relative angular movement between the cutting head and the pole. The connection may be a coil spring. The operating mechanism includes a 3-pulley system, one of the pulleys being mounted within the pole. A readily moveable sleeve mounted on the pole allows the flexible connection between the pole and the cutting head to be rendered inoperative if desired.
