A pair of pincer-type cutting blades are pivotally supported from a frame to be mounted from a front loader and fluid cylinders having base ends pivotally supported from the frame outwardly of the remote sides of the cutting blades include outer ends universally coupled to the front ends of the cutting blades, the pivot axes of the cutting blades and the base ends of the cylinders being substantially parallel and the cylinders being downwardly and outwardly inclined toward the free ends thereof relative to a plane normal to the aforementioned axes, whereby the cutting blades, during movement toward their closed positions, are slightly downwardly and laterally displaced at their forward ends. A front loader including forwardly projecting lift arms is provided from which the aforementioned frame is supported and the front loader includes a forwardly spaced and downwardly directed spray head intermediate the lift arms thereof for downwardly directing a spray of vegetation killer upon a cut tree stump.

A tree shear including a frame having front and rear sides, a pair of elongated, laterally spaced and reinforced support arms having front and rear ends and mounted at said rear ends from said frame for pivotal movement relative to said frame about first axes in pincer-like fashion and with said front ends projecting forwardly of said frame, said frame including opposite side forwardly projecting extensions, a pair of fluid cylinders having base ends pivoted from said extension about second axes generally paralleling said first axes and outer ends pivotally connected to said front ends, a pair of opposing, pincer-type cutting blades mounted on said support arms, extending longitudinally therealong and including cutting edges offset laterally outwardly of the adjacent sides of said support arms and front and rear ends corresponding to the front and rear ends of said support arms, said first axes being disposed in a plane spaced rearward of a plane containing said second axes, the pivotal connections of said outer ends to said front ends being disposed in planes normal to said blades and spaced no more than ⅓the distance from the front ends of said edges toward the rear ends thereof.
