Abstract
A tree cutting device for attachment to a prime mover, such as a bulldozer is provided. The attachment includes a v-shaped blade and a mounting means for attaching the v-shaped blade to the prime mover. The v-shaped blade comprises a pair of sheer blades joined at a forward convergence point to form the cutting edge of the v-shaped blade and a pair of concave shaped blades attached to the sheer blades so as to form an integral unit. The concave shaped blades in conjunction with the v-shape of the apparatus provide a means of controlling and directing the fall of trees being severed by the tree cutting device.
