New Holland SP.275R


Guardian Rear Boom Sprayers SP.275R


New Holland Guardian™ Rear Boom Sprayers deliver even, efficient product application with comfortable and easy control. 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. New Holland offers two Guardian rear boom sprayer models. Choose the model with the horsepower, width and tank capacity that best suits your needs.
