It’s unlikely you’ll find this size cord available locally. Designed for use with the DR Field and Brush Mower Bladeless Mowing Attachment, it’s much heavier than the cord used on standard hand-held trimmers. The extremely heavy-duty 170 mil (0.17″) cutting cord is available in 1 lb. rolls.
When the 1 lb. roll of 170 mil (0.17″) cord is used with the Bladeless Mowing Attachment for the Self-Propelled DR Field and Brush Mower, it yields approximately (56) 21″ cutting cords. The Bladeless Mowing Attachment uses (2) 21″ cutting cords at a time. Cord will need to be cut with wire cutters or tin snips.
