So i'm new to the business, I've been mowing lawns for years now, but only now starting to take it serious. So with serious lawn care, comes serious equipment. Now, I've decided on an all Stihl handheld line up, but still working out the specifics, like, what is they're best whipper snipper, chain saw, hedge trimmer, and BP Blower (with that said, I see a whole lotta numbers I don't get when researching these things, that's why i need some expert advice. For instance: I'm looking at the "Stihl FS 56 RC-E" And under power there is "KW/HP" I take it the HP is horse power, but what does the "KW" stand for, and what is considered good? Sorry if this is all incoherent but as I said, I'm new. Also, How much could I expect to pay for This In american or canadian $, cause I cannot find the price info I need on that. Thanks for any help. -Jeff ALSO: When mowing, is there any advantage to mulching/leaving the clippings? or is it always best to pick them up/bag them??
