Patent ID: 7422041

Claim:
A tree trimming device comprising: an anchor structure comprising at least one structural component and at least one clamping mechanism extending from the structural component of the anchor structure to a tree in a direction substantially perpendicular to the tree to clamp the anchor structure onto the tree through a force applied against the tree along the clamping mechanism along a substantially linear path to a point on the tree; a cutting assembly comprising at least one structural component and at least one clamping mechanism extending from the structural component of the cutting assembly to the tree in a direction substantially perpendicular to the tree to clamp onto the tree through a force applied against the tree along the clamping mechanism along the substantially linear path to the point on the tree and at least one cutting mechanism disposed to shear limbs from a tree; and at least one extendable piston connected to the anchor structure and the cutting assembly that may operate to change the distance between the anchor structure and the cutting assembly; wherein at least one clamping mechanism of each of the anchor structure and the cutting assembly comprises at least one horizontally mounted piston that makes contact with the tree when extended.
