ABSTRACT:
A tree cutting apparatus includes a frame having forward and rearward ends, with a pair of generally planar blades rotatably mounted on the forward end of the frame. The blades are mounted spaced apart within the same plane, each blade having a cutting edge extending around a portion of the periphery thereof. Each cutting edge has a forward and rearward end, with the cutting edge being spaced a distance from the rotational axis of each blade increasing from the forward end to the rearward end, such that the cutting edges of the blades move closer to one another as the blades rotate to cut a tree or the like.
