Air Blast SprayerI made this "air blast" sprayer using the fan from an old orchard sprayer. It mounts on the back of my field sprayer and runs off the field sprayer pto drive. I made the frame out of I-beam, channel iron and tube steel and used swivel wheels from an old David Bradley hay rake. It's fitted with an 8-roller pump, pto-driven by #50 roller chain so that it runs at 1,000 rpm's and produces 200 psi. The pto shaft runs under the tank and axle. The fan is driven by #80 sprockets and chain. I attach the sprayer to the back of my field sprayer with two pins.
I've used the machine 4 years with little servicing other than oiling the chains. It works as well as any commercial air blast sprayer on the market. I built it so I wouldn't have the maintenance of two separate sprayers and it cost just $300. I use the same valves to control the air blast sprayer as I use to control the spray booms. The 200 gal. tank lets me treat 4 acres of vegetables on one fill. To disconnect, I just remove the two pins and unhook the hoses.
