Abstract: A portable power saw apparatus is disclosed having an endless saw chain driven about a bow bar by an internal combustion engine. The apparatus includes a pair of transversely spaced legs respectively secured to the chain guide adjacent the outer end thereof and extending downwardly therefrom. The legs provide a ground-engageable abutment to support the outer end portion of the chain guide and saw chain, and they also define a size guage determinative of the largest diameter object acceptable between the legs for severance by the saw chain. Skid means secured to the handle structure of the apparatus is oriented at substantially the same elevation as the legs and forms a ground-engageable means therewith to support the saw apparatus in a generally horizontal orientation in certain operating modes.
