Air-O-Fan's NT-32 300, and 500 gallon "V-tower" sprayers have become popular throughout the United States vineyard growing regions because of the tremendous canopy coverage it achieves. Unlike conventional fan housings, the SE directs all the air and chemical to the canopy for superior coverage reducing drift and expensive chemical waste. Directional air vanes help fine tune your coverage for different canopy heights and trellis designs. The NT model is ideal for hilly terrain and spraying side hills. If you're in hilly areas or the row ends are tight with not much room for turning, Our DK turning hitch is the best in class to give tight controlled turning with minimal set up and maintenance. The DK turning hitch is available on all Air-O-Fan PTO drive sprayer models. The DK turning hitch allows the operator to make tighter turns than a conventional draw-bar hitch and reduces PTO clatter while also utilizing a standard U-joint PTO shaft (NOT A CV SHAFT). The NT model line is available in several tank sizes: 300 gallon, and 500 gallon and if your tractor horsepower is limited, take a look at our SJ-line vineyard sprayer models with a 30" steel axial flow fan which can be tuned to accommodate a 35 to 40 horse power tractor. - Less
