I am in the market for a trim mower. Right now I dont use it that much except to do my lawn (only 5000 sq. ft.) and a few touch up areas on some properties but I know as I acquire more accounts I will have more use for it. My question is what is a good brand for durability and price combined? Should I stick with a commercial mower? How many horsepower do I need minimum? Right now I have a Craftsmen 6.6HP self propelled but it is old and unreliable so I need to get one I can count on all the time.
