My first stringer trimmer for my home was a light duty Toro corded electric unit. I got 15 years of use before it died. I bought another Toro but it lasted a few years. Next I tried a Weed Eater product which also lasted a couple of years. I figured it was time to try a cheap Harbor Freight (HF). This unit lasted 10 years before a ten cent plastic part in the head gave up the ghost. This unit was replaced by a Kobalt. I thought I might get the HF running again by replacing the head. I cut the old plastic head off and removed the retaining nut that was peened on to the shaft. The shaft thread is M6-1.0 RHT and it rotates CCW. I bought off Amazon a M6 female to M10 male RHT thread converter. I put old head I had and now its back in business.
