A second member comprising a blade is pivotally mounted to the first member, with the first and second members being positionable on opposite sides of the body of a tree. Extension of a cylinder interconnecting the second member and frame means provides a scissoring action of the first and second members to provide shearing of the tree. Means are included for providing that upon withdrawal of the second member from the body of the tree, the first member is also withdrawn therefrom.
