A robotic tree trimmer has a hydraulic system adapted to be mounted to a tractor and comprising an extendible vertical mast. A first hydraulic motor attached to the vertical mast and adapted to linearly extend and rotate the vertical mast 180 degrees around a first vertical axis. An extendible horizontal boom attached to a distal top end of the vertical mast and having an extension member on an end opposite the distal top end of the vertical mast; a second hydraulic motor attached to the extension member and used to rotate a trimming apparatus 360 degrees around a second vertical axis variably spaced from the first vertical axis by the extendible horizontal boom. The trimming apparatus including a trimming member and a hydraulic piston that is attached between the trimming member and the extension member at a position that is spaced from the connection between the second hydraulic motor and the trimming member to thereby provide the ability to pivot and adjust the angle of the trimming member with respect to the horizontal boom, such that the trimming member can be moved in a variety of positions, angles, heights in order to trim trees of varying positions and sizes in a variety of desired shapes. |
