I was searching the internet looking for a super lightweight side dishcharge push mower for steep hills and I happened to find these supaswift mowers. They have 18 and 21 inch super lightweight mowers with small Honda engines. They look like they are made for commercial use and they look light as a feather. They also have twin blades. They call them disc blades. Ball bearing wheels. They are very expensive though, the 18 inch is $500. Does anyone have any experience with these mowers? I know none of the dealers around me sell them but it looks like you can order them off of the internet. I was going to just drop 120 or so on a cheap lightweight Murray but if I can get one of these and have it last me some years, I might consider. They even have a four blade self propel mower, interesting.
