Kind of an all-in-one type of tools. I wouldn't be surprised if someone does not steal my concept and invent just such an item of yard equipment! Among the major reasons I intended to do this particular review is because I acquired the Black as well as Decker LST220 trimmer last week as well as enjoy it.

My old gas powered one died so I made a decision to provide a cordless one a shot. Below is my take on it up until now.


lightweight, effective, lithium ion batteries (more power as well as the cost lasts a lot longer compared to NiCad), auto line feed that actually works!

I reside in a typical dimension rural house as well as trimming the front and also yard was not a problem whatsoever on one battery.


I'm 6' 2 ″ as well as at first I seemed like maybe possibly an inch much longer however after really utilizing it for a while it was just fine. It occupies to 8 hrs. to fully bill a battery. (Not truly an issue for the ordinary residence user).


With all the testimonials done on this site we always share the cons along with the pros with you so you could make an informed choice prior to purchasing.

Today is no exemption to that policy. You currently know that I enjoy this trimmer as well as lawn edger mix yet there were a few people that really did not feel the very same one.

I extremely recommend the Black as well as Decker LST220 GrassHog and also hope you will certainly go to Amazon as well as find out more consumer endorsements. Backyard work is a whole lot less complicated with a GrassHog!
