Said guard portions (32,34) including a forward (32) and rearward (34) guard portion, the rearward guard portion (34) in overlapping relation with a depth guide (50) of the cutting link (12L,12R). A relief spacing (42) between the guard portions (32,34) facilitates chip carriage and the guard portions (32,34) cooperatively form a ramp to guide wood being cut over and onto the depth gauge (50) for controlling the depth of cut taken by the cutting link (12L,12R). <IMAGE></p> |
