Miller Sprayers have been a trusted name in self-propelled spraying equipment for decades, with a long-standing relationship to dealers like Messick's who have supported them through various ownership transitions. Known for their front boom design and high-clearance models, Miller sprayers are relied on by professional applicators for precision and performance.

Over time, key components such as spray nozzles, pumps, valves, control modules, and electrical systems experience wear from constant use, exposure to chemicals, and varying field conditions. Regular replacement and maintenance of these parts are essential to ensure accurate application rates, consistent spray patterns, and reliable operation across changing terrain. Keeping these systems in top condition helps prevent costly downtime during critical spraying windows and maximizes the machine's overall productivity and lifespan.

During CNH’s acquisition of Miller, the company was split into two product lines: Miller and Miller Pro. CNH Industrial acquired the Miller brand in 2014, primarily for its self-propelled sprayer technology—especially the industry-leading front boom sprayers—and integrated it into the New Holland application equipment lineup. Meanwhile, the Miller Pro line, which included pull-type equipment like forage wagons, pull-type sprayers, and hay tools, was not included in the CNH deal and was sold off separately.
