Abstract
The present invention relates to heavy duty wood cutting shear attachments of a large scale for connection to a boom structure of a hydraulic excavator for cutting tree stumps and the like. The wood cutting shear includes a swingable jaw and a stationary jaw. The swingable jaw has a C-shaped frame with a knife like cutting blade affixed therein. The stationary jaw includes a stump supporting section having a blade receiving slot with a width of approximately the thickness of the cutting blade. Besides slicing through a stump placed between the jaws, the knife like blade may cooperate with the stump supporting section to shear portions of the stump being sliced.
