I have stored several tractors/mowers/ATV's in an unheated barn. Batteries don't like the cold, so all vehicles are connected to battery tenders. These side panel openings eliminate the need to lift covers or bench seats to attach alligator clips to battery posts at the end of each workday. Turn them on at night, turn them off and go to work in the morning. Easy. I have six of these.
