Stay away from craftsman. I love their wrenches and hand tools,but I have had nothing but bad luck out of their lawn equipment,regardless if it says "commercial" grade or not. I had problems out of craftsman before I started cutting grass for a living. As I am typing this I am looking out of my window and seeing my $1800 craftsman mower that started burning oil within 5 hours of use. A few years ago I bought a craftsman trimmer to use for a day or two while my stihl was being serviced. I purchased it,drove 45 minutes to the first job of the day,and on the first pull of the cord,the cord came out of the housing. Nothing but junk,but this is merely my opinion. On the other hand I have a honda hra pushmower from 1994.... I use it for commercial use,and it smokes on start up...but the son of a gun never fails to start and perform.
