we run walk behinds as much if not more then the ztr's. they're efficient, low maintenance, fast and great tools especially in the average sized half acre including the house driveway etc subdivision lawns. I didn't start running ztr's until we started getting bigger lawns. I've never plowed with my mowers and never will. its a waste of time IMO I've a snow dog vxf85 I don't like doing driveways but if we have our parking lots clear we'll go do them. it takes me 3 minutes to back drag push away from their entrance and my passenger will shovel the sidewalk and collect the cash usually $25-30. never forget they called you because they need your help getting out.
