ABSTRACT:
A dual action tree cutting apparatus includes a single generally planar blade mounted on a shaft at the forward end of a support frame, with the blade projecting forwardly therefrom. The blade has a cutting edge extending around the entire perimeter, and has two mirror image halves divided by a centerline passing through the shaft. Each blade half cutting edge increases in the distance between the cutting edge and the shaft along the perimeter from a rearward end of the centerline to a forward end of the centerline. A set of cutting teeth are formed on one blade half and oriented to cut a tree when the blade is rotated clockwise, while a second set of cutting teeth are oriented on the second blade half perimeter to cut a tree when the blade is rotated counterclockwise. A sprocket on the shaft is engaged by a pair of drive chains connected to operable cylinders, the cylinders operable to retract and pull one drive train to rotate the blade in each direction.
