The straight shaft design with a standardized coupler provides extended reach under bushes and shrubs and the use of attachments. Includes 10-inch brush cutter blade, bump head with .095 spiral trimming line, and harness strap. All SENIX 4QL gas powered products are backed by our 3-year limited warranty for your peace of mind.
