Abstract
A tree cutter in combination with a self-propelled vehicle is disclosed for cutting underbrush and small free standing trees, such as, Cedar. The tree cutter is pivotally mounted at the front of the self-propelled vehicle, such as, a Four Wheeler in order to pivot upon a horizontal axis. The tree cutter provides a frame assembly that includes a discrete pair of triangular straight edge blades followed by a pair of circular blades that rotate in opposite directions caused by contact with the inner core the tree. The blade pairs are adjacent, oppositely disposed, and selectivly spaced apart as included in the frame assembly.The blade pairs act in synergy as they are driven into the tree by the vehicle, wherein the straight blades are suited for slicing into the soft outer vascular core of the tree, thereafter shearing force of the rotating blades is applied to the harder sapwood and heartwood that are engaged between the rotating blades.
