Abstract
A saw blade for a tree felling head has three tipped teeth in which only one tip of each tooth is exposed outside of the blade disc. Around the circumference of the blade, teeth with tips exposed on the upper side of the blade alternate with teeth having tips exposed on the lower side of the blade. Axes of the teeth are tangent to radii of the disc and angled upwardly or downwardly relative to the plane of the disc, and mating surfaces on the teeth and disc at 45.degree. to the plane of the disc abut against rotation and loading of the teeth.
