Motorized Nitrolator

A farmer made a Motorized Nitrolator for his anhydrous ammonia applicator by replacing the trip rope with an old windshield wiper motor. Thanks to the motor’s internal switch limit, one punch of a button in the tractor cab causes the motor to make a complete revolution, turning the Motorized Nitrolator on; a second punch turns it off.
