Carriages for the sprinkler head clamps are biased by springs toward the center of the attachment. The bottom of the attachment has a plurality of longitudinally spaced blade sockets. Downwardly extending cutting blades may be inserted into the blade sockets to adjust the distance between the blades. A center brush extends downward between the cutting blades.

Abstract: A lawn trimmer attachment for trimming sprinkler heads has downwardly extending cutting blades which may be inserted into the blade sockets to adjust the distance between the blades. An adjustable lawn edging attachment for trimming around sprinkler heads comprises a body, an adapter extending upward from the body, two or more elongated arms extending outward from the periphery of the body, two or more blade sockets along a longitudinal direction on a bottom side of each of the two or more elongated arms, and a blade extending downward from the bottom of each of the two or more elongated arms. The adjustable lawn edging attachment further comprises a spring biased interlock pin on the distal end, where the spring biased interlock pin extends through the blade base to lock the blade into one of the two or more blade sockets on each of the two or more elongated arms.
