Original value, age, features like Self Propelled?, 4 stroke? I usually ask myself what is the minimum dollar amount I need out of this item. I've realized the time & hassles of "selling" are sometimes met with just listing an item for free if someone else can use that item. Granted not something like your post here as that sounds like it has some value. This question often doesn't have a specific answer other than it depends on your area or market. What sells in California may not sell well in Florida. Can't really say any dollar amount as there are other details missing along with what you feel is needed back out of it. Otherwise try pricing it at what you need back out of it plus a few bucks and see if you have any buyers. If not then reduce the price over several weeks until you get some attention on it. Good luck!
