My Personal Experience with BLACK+DECKER GH900 6.5-Amp 14" String Trimmer/Edger

This spring I purchased two corded string trimmers from different manufacturers and they all failed miserably. I wanted automatic feed system but unfortunately, none of them worked properly. I was somewhat hesitant at purchasing this automatic feed string trimmer especially after reading reviews indicating the owner used entire spools of string every time they used their trimmers. Still, I decided to take a chance and after use of 6 months, I am glad to report that my trimmer has worked flawlessly. I've always been for the gasoline weed eaters and never thought this would work.

I live in Southern California and after a serious rainy winter, the weeds were out of control this spring and taller than they've ever been. Its assembly was quick and I was ready to go within 5 minutes: all that was need was to install the 14-inch guard and to mount the grab handle on the shaft. Right out of the box there is the line guard and the handle to attach and that's it. I plugged it in and made very light work of my overgrown lawn edges and weeds. This string trimmer and edger was not only good at taking out the shorter grass, but we did a whole big yard of everything else as well, 1 feet plus weeds with some having up to 2 feet. I also trimmed trumpet vine with no problems. I was not expecting the power and ferocity this machine dished out to my weeds.

I have a fairly good size lawn with lots of trim work required each time I mow my lawn. I averaged about one spool full of line for every four times I mowed the lawn, which for me is great. The automatic line feed system worked brilliantly. Also, this model has only one line, which I prefer. The dual feed line trimmers are difficult to load and unnecessary because of the GH900's high motor RPM speed. Besides, when you have a jam in the trimmer head out in the field, you can quickly disassemble and re-feed the single line quickly even while wearing gloves.

However, with the guard, I don't have to worry about chopping up my other ground plants. It snips right to the edges and cleans up perfectly. I feel the same with the edger (which I have never had a wheel and guard). It's easy to use and I don't have to worry about hitting my pavement. The wheel on it I totally thought was a gimmick when I bought this but it actually comes in quite handy while edging down the driveway. The wheel design is quite smart, it eliminates having to bear the weight of the trimmer when used for edging since the wheel takes care of that and rolls smoothly across grass or hard surface. I wouldn't say I am an experienced trimmer or edger by any means but the lines comes out pretty good.

What Is Automatic Feed Spool (AFS)?

This AFS technology will eradicate bumping for hassle-free line feeding that assists you to work without disruption.

Does It Come With Spool String?

Yes, it comes with a spool that has a very little string on it. It didn't even last through one trimming. You can easily get it from anywhere. It is always better to keep 3 to 4 autofeed replacement spools extra.

Is This String Trimmer/Edger Quite?

No, it is not loud. Your neighbors will not even know that you are trimming your lawn. I have done my lawn's trimming at 6 o'clock early morning and no complaints from neighbors.

Is There Any Specific Extension Cord That Has To Use?

No need to any special extension cord. It should be three pin outdoor extension cord. I would suggest you to buy 100 ft extension cord as you can utilize it anywhere anytime. If you will buy 50 ft extension cord like me you will regret later on. I bought new 100 ft for my medium size yard.

How Do You Clean The Trimmer After Use?

If possible avoid cleaning trimmer with water as water could send grass and dirt further into the workings of the trimmer. It might create a problem for your machine. I have cleaning brush set, I use that to knock off the grass.

I highly recommend this product if you are looking for an inexpensive/ powerful solution to your everyday lawn maintenance needs. This is solid and simple edger for your lawn. It's made of quality materials, has a telescoping shaft for comfortable use by every height user (I'm 6' 01" tall and It's perfect for me). It's light weight, but most of all the automatic single line feed system works perfectly. I highly recommend purchasing this Black & Decker GH900 string trimmer. It is a great product and well worth every penny.
