Great price
I bought this cause I was looking for a inexpensive trimmer and considering the price this is everywhere else I couldn't pass it up. I had trouble fixing the spool as the instructions are not clear. But other than that so far it's great works great. I've had no problems so far.

No, I would not recommend this to a friend
I have a medium size yard and yet I was unanble to go half way around the perimeter without having to add line three times. I do not thing that could be considered normal usage.

Try something else
This trimmer uses too much line. Went through three reels (over $23) within 30 minutes of trimming. Also line feed keeps getting stuck.
Will need to buy something better.

Is there an attachment that allows electric to be used with my battery trimmer
DON on May 21, 2015
BEST ANSWER: No, this trimmer cannot be adapted to work with a battery.
Can you respoll the heads once they run out of line or do you have to buy already spooled replacement heads? I see they are almost $10. If you have to buy replacement heads with line on them already how quickly do you go through one pre-lined head? A month? All summer? Thanks!
Rocky on Jun 15, 2014
BEST ANSWER: Yes, you can rewind the spool. Directions can be found on page 8 of the manual. Here is a link to the manual:,GH900.pdf
Can you tell me what is the name of the replacement string? I would like to buy the trimmer, but I can't seem to find what you use when the string runs out?
Ed on May 18, 2014
BEST ANSWER: The size of the line is 0.065 in. The model number for the auto-feed trimmer line spool is model AF-100.
The GH900 as an edger baffles me. I need a picture of what it should look like in this mode. Manual is very unclear. Even GOOD instruction would help.

Thanks much!

BEST ANSWER: Here is a link to Black & Decker's website. If you click under the picture of the trimmer on the image, you can see the edger in use.
