Abstract
A power take-off system for attachment to the elongated bar of a chain saw. A shaft is rotatably carried by a housing which is attached to the bar of the chain saw. A gear is carried on the shaft and is located in a transverse aperture in the bar such that the gear is driven by the nose sprocket in the bar. The housing serves as a guard over the chain on the bar also. The power take-off system may be provided as a self-contained integral unit which replaces the existing cutting bar on the chain saw.
