Trimmer Head Assembly for DEWALT DCST990, by DEWALT

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!"

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.

Love all of my Dewalt tools except but the head design on this product is terrible. When I am able to get the string to loaded the trimmer works great until I try to advance the string then its back to square one.

The trimmer itself is very good. However, the trimmer head is poorly designed. The strings often/always got cut off or damaged during trimming. Design of the trimmer head is supposed to allow releasing or unroll of the rolled strings in the case automatically to keep continous trimming. On every trimming event, the string got cutoff within a few minutes. I had to open the case, pull the string out and that broke or cut off within next couple minutes. I had to repeat this to 4 times everytime I trimmed my lawn. A proper trimmer string should have smoother surface, does not tangle, and allow automatic unrolling or releasing of the string once it got cutoff without interuption during trimming. I plan to purchse DW01DT995 to give it a try, seems to be a better design by looking at it. Both trimmer head design and Dewalt branded trimmer string surface smoothness should be improved.

I thought I was the only one with the problem of having to fix the line due to breakage or having difficulty reloading the line on the spool. Obviously I'm not the only one. Obviously If I had known that I was going to have this problem, I would have picked another brand. Seriously, it's a pain.

I bought this trimmer because I have other Dewalt products and they are good. This is a pain in the neck. The string must be repaired after every use and the replacement head is often difficult to remove. I am disappointed in this product and could have gotten other trimmers for a lot less money.

I bought the weedeater and looked forward to using it but this makes the product unuseable need better design!!!!!

Cuts the line when it shouldn't, not release line when it should! Should i continue? The spooling of the line is incredible difficult and comes off very easy. This is the worst design made by any Trimmer manufacturer and definitely you wouldn't expect this from such a reputable company like Dewalt. For all the users that got this product and cannot use it, provide a free head replacement with a better design. For the Dewalt development team, ask them to use this just for 30 minutes with spooling new line and if they are intelligent enough they will come up with a great design.

I am a loyal Dewalt power tool user. I love the trimmer yet the spool/line is a joke. Come on Dewalt, who engineered this disaster? Takes forever to reload spool and then constantly breaks off inside head. It takes a contortionist and lots of luck to reload the spool. Any chance for an upgrade or is this a lost cause and destined to a garage sale?

I have a number of DEWALT products and have really enjoyed them. Until this trimmer! It is just awful! The line is very difficult to load then it breaks off inside the head, or just won't feed correctly. If you have any suggestions for me I'm all ears! Steve
