ABSTRACT:
A chain saw attachment for a portable chain saw. The chain saw attachment comprises a cutter head journalled on the cutter axle and having four planing knives, two mounting arms removably securable to the chain saw bar, a chain sprocket engaging and being rotated by the saw chain, a driving sprocket rotated in response to rotation of the chain sprocket, a driven sprocket fixedly attached to the cutter head, and a planer chain engaged by the driving and driven sprockets so as to transmit power from the saw motor to the cutter head. The planing knives are arranged conventionally on the cutter head. The mounting arms the ends of the cutter axle so as to hold the cutter axle and cutter head perpendicularly to the saw bar. A planing guide is provided for use with the planer attachment. The planing guide has two side members, and forward and rearward guide members affixed to and respectively positioned forwardly and rearwardly along the side members so as to define a cutting plane determining the depth of cut of the planing knives. Vertical slots in the side members pivotably mount the planing guide on the ends of the cutter axle and allow the planing guide to be positioned vertically with respect to the cutter axle, thus providing a precise depth adjustment mechanism for maintaining a selected depth of cut.
