In combination: a) a cutting blade assembly having a frame and a first cutting blade member with a first cutting edge portion configured to cause relative movement between components on the cutting blade assembly whereby the at least first cutting edge portion effects severance of an object; and b) a protective sheath. The protective sheath can be moved relative to the cutting blade assembly between: a) a first separated position; and b) an assembled position. The protective sheath frictionally engages the cutting blade assembly to thereby be maintained in the assembled position. The protective sheath has at least one component that projects away from the cutting blade assembly and has oppositely facing surfaces that can be grasped between two fingers on a user's one hand to facilitate repositioning of the protective sheath.

Protective sheath for cutting blade assemby

An edger has a main frame that can be advanced controllably relative to subjacent terrain and a cutting assembly on the main frame. A drive rotates the cutting assembly around a first axis. The cutting assembly is configured to produce a trench in underlying terrain as the cutting assembly is rotated by the drive in operation. The cutting assembly has a perimeter edge with a contour extending over an axial distance. A shielding assembly defines a radially inwardly facing surface that resides radially outside of the perimeter edge of the cutting assembly. The radially inwardly facing surface has a shape that is at least nominally matched to the contour of an axial extent of the perimeter edge of the cutting assembly so that as the cutting assembly rotates the radially inwardly facing surface and perimeter edge of the cutting assembly cooperate to each avoid buildup of foreign matter on the other.
