Your looking at the stihl rma 370. Its a great machine. I am a stihl dealer in southern illinois and i have one here on my floor. You should be able to get all the info on stihlusa.com. It really is a great system. Its just a very expensive initail cost. But then you never have to buy oil, gas, spark plugs, fuel filters or anything related to the traditional lawn mower engine. It will also start everytime you want it to. And they are super quiet!!
