ABSTRACT:
An edger blade uniquely designed to cut into the surface of the ground thus loosening a portion of the dirt, lifting the loosened dirt from the ground, and throwing the dirt to one side. The blade is adaptable for mounting on most home garden edgers powered by internal combustion engines. The blade has a central hub portion provided with a shaft hole adapted to permit the blade to be mounted on the edger shaft. Two arms extend from opposite sides of the central hub portion to form hoe portions that perform the hoeing operations of the invention.
