I have been using this lawnmower for about the last 10 years and have been very happy with it.  Just last week the "self propel" feature stopped working.  The engine starts fine and cuts well but something in the propel feature does not work but I suspect can be fixed.  I went ahead last week and ordered a new Toro similar to this one since it has treated me well over the years.  Any one interested in this one that needs some work on the "Self Propel" feature?
