Tree cutting equipment that may constitute a part of the head of a tree harvester includes a saw assembly and a shear assembly, the shear and saw being movable towards each other, preferably in substantially the same plane. A stop associated with the shear assembly and engageable with the saw assembly limits the extent to which the saw can approach the shear so as to prevent the saw from attempting to cut completely through the trunk of a tree located between the shear and saw. The stop is located on the side of the pivot point for the saw that is remote from the shear, and a window is provided in the arm that supports the shear to permit the ejection of saw chips.
