Friend maintains MILES of walking trails in the woods for recreational use... for the public... all at his own expense!? He is wondering about a QUIET mower for this purpose. http://www.youtube.com/watch?v=i0AqFL2ltjA. He is looking at this, and asked my opinion. I do not think this would be the ticket as the debris alone on the trails would be it's down fall. Currently he uses old discarded gas push mowers that I keep running for him. Has a couple old riders as well for larger areas, and roughing in new trails. Any thoughts on ...silent... mowers that might work out? Yes... it would be in a limited capacity these could be used, and he understands that. Personally... I do not think they would work well, seeing what he is doing but told him I would post here and ask.
