A tree shear and delimber for harvesting trees comprising a self-contained wheeled vehicle with a power-operated tree-severing means pivotally mounted on a normally horizontal axis at one end of the vehicle for severing a standing tree with a horizontal cut at one side of the vehicle and for severing a fallen tree into sections with a vertical cut, and power-operated delimbing means mounted on the other end of the vehicle. The delimbing means comprises a pair of generally open L-shaped cutting blades moveable with respect to each other into surrounding relationship about the trunk of a tree, and a pair of power-operated tree-feeding spindles moveable into engagement with opposite sides of the tree trunk to draw the tree through the generally L-shaped blades and remove the limbs from the tree. The severing means at the other end of the vehicle also operates to sever the trunk into sections as it is drawn through the L-shaped cutting blades.
