ABSTRACT:
A pruning device for cutting limbs includes a hollow tubular pole having an actuating assembly mounted on a first end of the pole, and a cutting assembly for engaging and cutting a limb mounted on a second end of the pole. A cable extends axially through the pole. The cable is connected at one end to the actuating assembly, and at the other end to the cutting assembly. The actuating assembly applies pulling force to the cable upon its operation. The cable triggers operation of the cutting assembly when the cable is subjected to pulling force. The cutting head includes a hook adapted to receive the limb, and a cutting blade pivotally mounted to the hook for cutting the limb. The blade pivotally moves toward the hook upon operation of the actuating assembly. The cutting head also includes a pulley assembly through which the cable is run upon exiting the pole. The pulley assembly effectively increases the force with which the blade moves toward the hook by increasing the pulling force applied to the cable. The pulley assembly also draws the cable tight during operation of the pruning device. The cutting head is disposed inside a package that allows for operation of the pruning device without removing the cutting head from the package.
