I try to master the names of each implement so that I don't sound like an idiot when in the presense of those that know. However, when talking to those that know little or nothing you have to call the implements by both names until they figure out what the heck you're talking about when you say you have a 10" moldboard plow. Otherwise you can get the response, "That won't move much snow in the winter." LOL
Well there you or I go with the regional lingo. Out here we either push or plow snow, but the implement used to do so is always a Blade. If it blown we use a blower.
