Billy Goat offers a propane fueled vacuum and I was wondering if anybody has done any conversions from gas to propane for mowers etc. We have severe air pollution problems here and have been getting calls for no drive days on a voluntary basis. A bigger concern is the last few years this has expanded to asking that no lawn equipment run on the same days. I can see these requests turning into requirements. Maybe or maybe not, but if it is practical I would like to try propane as an alternative now and use it as a selling point. And no, my name is not Hank Hill.
