Rugged construction and the simple mechanical drive system perform dependably season after season and improve your fuel efficiency and return on investment. A compact design offers an exceptional 15-foot turning radius for easy maneuverability. Four equal-size wheels provide a better ride, better turning radius and less compaction than sprayers with smaller front wheels.
