ABSTRACT:
A chain saw mountable on a powered vehicle having a chain support with a loop-defining chain run including an exposed cutting run portion. The chain support has a lower surface which defines a lower tree-cutting surface along which the lower support surface travels during cutting. The non-cutting run portion of the chain loop is disposed coincident with or above this lower surface. The upper surface of the support covers the non-cutting run portion and has a general wedge-shaped tapering toward the cutting run portion.
