Husqvarna RA850 weed scissor attachment compatible with select handheld combi tools. Designed for safer trimming and edging along sidewalks and near gravel paths where an ordinary trimmer could throw rocks or debris. The durable, reciprocating blades move back and forth to cut the grass in a scissor motion similar to a hedge trimmer. Compatible with Husqvarna's LK Series battery and gas combi tools (535LK not included).
