A machine for felling standing trees, cutting logs into segments of the desired length and splitting logs lengthwise. A shear blade is mounted for reciprocal movement within a framework by means of a hydraulic cylinder or cylinders so as to urge the log against an anvil at the rear of the frame upon the forward cutting stroke. The frame is pivotably affixed to the drawbar lift assembly of a tractor so as to be rotatable between a horizontal attitude for felling standing timber and a vertical or upright attitude for cutting and splitting logs. The anvil is pivotably connected to the frame, and includes an operating mechanism whereby it can be swung open to admit a standing tree and then closed and latched to sever the tree. The cutting edge of the shear blade is in the form of a V-shaped notch so that the log is stabilized while being severed in opposed directions upon the forward, cutting stroke. A saddle moveable along the frame with the shear blade laterally stabilizes the blade and, upon retraction of the blade, dislodges logs which may become stuck thereon.
