Tree pruning and trimming head
First Claim
1. An apparatus for gripping a tree, said apparatus being attachable to a carrier boom, said apparatus being usable with a cutting device for cutting a portion of said tree, said apparatus comprising:
- a body, said body being mountable to said carrier boom;
a pair of gripper arms mounted to said body, said pair of gripper arms being selectively movable between an open configuration in which said tree is insertable therebetween and a closed configuration in which said pair of gripper arms is able to grip said tree therebetween; and
a support arm operatively coupled to said body for supporting said cutting device, said support arm including a cutting device mount for mounting said cutting device thereto, said support arm being configured, sized and operatively coupled to said body in a manner such that said cutting device is rotatable relatively to said pair of gripper arms about three different rotation axes;
whereby, when said pair of gripper arms grips said tree, said pair of gripper arms stabilizes said support arm relatively to said tree and allows for the orientation of said cutting device relatively to said tree by said support arm.

Abstract
An apparatus for gripping a tree, the apparatus being attachable to a carrier boom, the apparatus being usable with a cutting device for cutting a portion of the tree, the apparatus comprising: a body, the body being mountable to the carrier boom; a pair of gripper arms mounted to the body, the pair of gripper arms being selectively movable between an open configuration in which the tree is insertable therebetween and a closed configuration in which the pair of gripper arms is able to grip the tree therebetween; and a support arm operatively coupled to the body for supporting the cutting device, the support arm including a cutting device mount for mounting the cutting device thereto, the support arm being configured, sized and operatively coupled to the body in a manner such that the cutting device is rotatable relatively to the pair of gripper arms about three different rotation axes; whereby, when the pair of gripper arms grips the tree, the pair of gripper arms stabilizes the support arm relatively to the tree and allows for the orientation of the cutting device relatively to the tree by the support arm. It is a general object of the present invention to provide a new and improved hydraulic tree pruning and trimming head attachment, hereinafter abbreviated simply as head attachment.
