Change this for Gas Power, performance, and simplicity are what make this new single fan orchard sprayer model so desirable. The G-40R can effectively achieve complete coverage in big and tall trees. Citrus, Walnuts, almonds, pistachios, tree fruit, cherries, and apples are just few of the trees this machine serves. The G-40R is powered with a fuel-efficient Ford Industrial motor, Myers© 2-stage centrifugal pump, and a 40" diameter axial flow "reverse" steel fan. This reverse fan design leads the industry by eliminating the leaf plugging issues commonly associated with conventional rears pulling fan designs. This design also eliminates chemical recirculation and makes daily service of vital components much easier. Coupled with our composite nylon adjustable air vanes, individual shut off valves, and ceramic nozzles, these technologies help direct the air and material to the desired location of the tree canopy for superb coverage, reducing chemical usage and drift.
