DeWalt trimmer head

The head that came with the trimmer was a frustrating experience to remove, restring and replace, eventually the string, which was recommended, broke off in the hole!!! So, necessitating a new head. I've only used it once so far and with new string both of which were installed by a wonderful employee at the store in which I purchased the trimmer. sS, time will tell. I was so exasperated, I almost bought a new one, also a De Walt, but found out it needed a different battery! I already have 3 for the original trimmer! so, fingers crossed, this head saves my sanity and "weeds, be gone!"

Exacty the same as the one on it.

This is exactly the same OEM trimmer head that came on my DeWalt 40v MAX /XR 990 strong trimmer. I highly recommend it to others.

My 20 volt trimmer is light and very usable.

I've had mine for about 5 years & I can't imagine going back to a gas trimmer. During the first summer I told people my grandson used it all the time, they didn't seem real impressed. Then I told them he would be in 2nd grade when school started in the fall, they almost fell over. Great trimmer combined with a hard working kid.
