Abstract: The present invention provides an apparatus for self-aligning pruning of trees. The apparatus includes a frame and a cutting tool that is attached to the frame. A power supply is connected to the cutting tool and there is a means for controlling the power supply. A support apparatus such as an Unmanned Aerial Vehicle is attached to the frame. The support apparatus can be controlled remotely such that it can position the frame horizontally and vertically. The frame includes at least one guide leg that is angled down and away from the cutting tool and the frame is connected to the support apparatus such that the frame can rotate relative to the support structure in the horizontal plane.
