Description Additional Information Maximum Capacity. Maximum Coverage. Built for the Largest Operations. The Bestway Ag Field Pro IV 1600-90, 1600-100, 1850-90 and 1850-100 pull-type sprayers represent the largest and most productive models in the Field Pro IV lineup. Designed for high-acreage producers and professional applicators, these sprayers combine industry-leading tank capacity with wide 90-foot and 100-foot FiberWorks™ boom systems to deliver exceptional productivity, efficiency and reliability in demanding field conditions. Proudly made in the USA in Hiawatha, Kansas, these flagship Field Pro IV models are engineered for operations where time, efficiency and coverage matter most. With tank sizes of 1600 and 1850 gallons, they offer the capacity needed to stay in the field longer and reduce costly downtime associated with frequent refilling. The largest Field Pro IV models are built with maximum productivity in mind and feature a larger capacity than many self-propelled sprayers, allowing operators to spray more acres per load while maintaining precise, consistent chemical application. Built to Compete with Self-Propelled Productivity For many operations, the Field Pro IV 1600- and 1850-gallon sprayers deliver the productivity advantages typically associated with self-propelled machines, without the added cost, complexity, and maintenance requirements. Their high-capacity tanks and wide boom widths allow operators to: Spray longer between fills Cover more acres per day Reduce labor and fuel costs Improve operational efficiency during critical application windows Maximize equipment utilization across large acre operations This makes these models an excellent fit for: Large-scale row crop farms Custom applicators and commercial spraying operations Farms managing extensive acreage across multiple locations Operations seeking high productivity without transitioning to self-propelled equipment Built for Accuracy in Every Pass At the core of the Field Pro IV platform is Bestway Ag’s V-Ride™ variable ride boom suspension, a proven system designed to isolate boom movement from the trailer chassis. Operators can fine-tune boom response based on terrain and field conditions, helping maintain consistent boom height and uniform spray coverage across the full width of the boom. The FiberWorks™ boom system delivers strength, flexibility and durability through advanced composite construction. Designed to withstand the stresses of large-scale field operations, the boom absorbs shock from rough terrain while maintaining structural integrity. A dual breakaway system helps protect the boom from damage, reducing downtime and repair costs. For operations requiring even greater precision, the optional AutoGlide XR2 automatic boom height control system uses rugged ultrasonic sensors to continuously monitor and maintain optimal boom height, helping ensure accurate, consistent chemical placement across every pass. Built for American Agriculture The Field Pro IV 1600- and 1850-gallon models are manufactured in Hiawatha, Kansas, where Bestway Ag builds equipment specifically for the demands of modern North American farming. From structural components to boom engineering, every detail is designed for durability, serviceability and long-term performance in real-world agricultural conditions.
